Murder For Hire is a case from the early 90s that concerns a murder for hire investigation. Billie Siko was a hitman who was involved in the drug trade, sex trafficking, and human smuggling.
00:05:03.820mildred horn was a 43-year-old divorced mother employed as an american airlines flight attendant
00:05:09.820she had been shot three times in the head her eight-year-old quadriplegic son trevor who required
00:05:16.380round-the-clock nursing care appeared to have been suffocated police found him disconnected from his respirator
00:05:23.900and trevor's overnight nurse 38-year-old janice saunders had been shot twice in the skull and that's where the noise is coming from guys uh with the respirator because once you know obviously some danger arises or their blood pressure goes down or anything happens with their vitals the machine starts to make a lot of noise so the nurse knows to come over
00:05:48.060evidence technicians began work immediately
00:05:54.060they were thorough but there was little evidence to collect
00:06:00.140they dug a single distorted bullet fragment from the wood beside trevor's window
00:06:06.220investigators took swabs of blood carefully collecting samples for dna testing
00:06:16.300but the blood would match only the victim's dna
00:06:22.300with so little to lead investigators to a suspect
00:06:25.500technicians scrounged harder for clues collecting anything and everything that seemed promising
00:06:34.220outside the house investigators found a metal file
00:06:44.860that's going to be very important later on guys so make a note of that they found the metal file outside of the home
00:06:53.020police were thorough but the killer had been meticulous
00:06:56.620they found the metal file inside the house
00:07:00.060montgomery county maryland homicide detective craig wittenberg named lead investigator struggled to make
00:07:06.380sense of a case with three helpless victims no obvious motive and a few clues
00:07:13.260there were some things that struck us so this was the lead investigator on this on this case guys uh typically uh when it comes to homicide and
00:07:22.380and and rotations whoever was on duty on that night is the one that's going to clean up that case when it comes through because homicide investigators are typically on call 24
00:07:33.020seven so he got assigned this case so as the main uh case detective or case officer in this case
00:07:38.140he's going to be the one responsible for gathering all the evidence writing the reports writing affidavits preparing search warrants and presenting the case to the ada or is a
00:07:48.380assistant district attorney for prosecution as odd
00:07:53.500i think from the very beginning of the on-scene investigation
00:07:58.300inside the house the foyer area a closet and that's actual uh footage from uh
00:08:06.380the the crime scene which you know in the early 90s
00:08:08.780had to bring in probably a big ass camcorder and lug that thing in and take video
00:08:12.300the contents had been dumped everything been pulled out of the closet dumped onto the floor
00:08:22.300we found a purse which we would later learn ultimately belonged to millie you had a lot of
00:08:31.420stereo entertainment equipment tvs a lot of jewelry furs
00:08:37.660that was untouched and left which again strikes you as odd if this is a if this is a burglary or
00:08:45.980robbery going bad you're going to take something
00:08:51.820which back then guys you got to remember back in the 90s right having that type of equipment was
00:08:56.220extremely expensive you know any type of entertainment television uh entertainment equipment vcrs cable
00:09:02.220boxes televisions all this stuff was expensive back in the 90s man so you know this was very unnormal
00:09:08.380for someone to break into the house it'd be all ransacked like that and no one actually take anything
00:09:12.700um you know it's not like nowadays where you can get a tv for next to nothing back then you know things
00:09:18.060were a little bit more expensive especially like good entertainment equipment so this was 93 93 way before
00:09:24.780you were born just a little bit yeah when were you born um yeah 99 god damn 99 barely 90s baby
00:09:34.540in fact mildred's minivan was missing from the garage as her sister had noticed
00:09:42.460but it was found quickly not far from the house
00:09:50.540so that's important they found a car not too far from the home
00:09:53.260some of mildred's credit cards were also missing
00:09:58.220but found the next day on a nearby roadside by a jogger
00:10:02.940gotcha with the closed caption baby investigators now positively eliminated burglary as a moment
00:10:09.740instead they wondered if the missing items were a deliberate attempt by the killer to throw them
00:10:14.620off his trail the scene had the earmarks of a planned professional execution
00:10:23.260as for a suspect at the crime scene vivian told the mildred's ex-husband lawrence
00:10:32.940horn was probably responsible man he said these uh captions are sucking right now
00:10:38.940but uh yeah so there we go guys we got our first suspect right now
00:10:42.940okay her husband ex-husband lawrence horn guys not lawrence home but lawrence horn
00:10:48.620he quickly became the prime suspect all the family members and just so you guys know typically the
00:11:02.300first person that's found at at the crime scene or the person that discovers the crime scene is almost
00:11:07.020always going to be heavily interrogated by the police they're typically the first suspect
00:11:11.500unless the police are able to quickly identify someone else so in this case right you had a
00:11:16.140divorced woman that was murdered you know a likely suspect a lot of times going to be the ex-husband
00:11:20.460so she's able to quickly say hey it was more than likely lawrence horn that was involved
00:11:24.860and and the police were able to divert their attention to him but you know if you find a dead body best
00:11:30.540believe that they're going to ask you a bunch of questions and you're going to be the primary suspect in the
00:11:34.380beginning with a homicide investigation because remember guys that first 48 hours is critical
00:11:38.700to them solving the case we're giving us this information that kept pointing to lawrence horn
00:11:45.980that would be based on the very stormy rocky relationship that millie and lawrence horn had had for many many years
00:11:59.020uh danny could you get this drum set up in number five for me please
00:12:02.380all right investigators learned that in the 1960s and 70s horn had been a top producer and recording
00:12:09.260engineer for motown records credited with many hits including shotgun by junior walker and the all-stars
00:12:17.340he'd married mildred an airline attendant in 1973. then he'd moved with motown from detroit to los angeles
00:12:25.740okay but when the company's fortunes waned so did his
00:12:33.180he and mildred divorced in 1987 but their problems continued
00:12:39.820as bob dean maryland assistant state's attorney soon discovered
00:12:44.620all right and when they say maryland state's attorney guys that's the equivalent to uh assistant district attorney
00:12:49.740same thing he's a prosecutor at the state level and as you guys know typically the state takes
00:12:55.100exclusive rights when it comes to premeditated murder investigations feds are only involved
00:12:59.660in murder investigations when there's some other type of prerequisite crime involved whether it was
00:13:03.900gang related racketeering rico influence it was during the commission of a federal crime like let's
00:13:09.500say a bank robbery but when it comes to murder in itself just standalone murder premeditated or
00:13:15.340otherwise it's almost always investigated by the state predominantly so it would make sense that
00:13:22.140you got a maryland investigator and then you got a maryland assistant district attorney uh involved in
00:13:26.780the investigation we did some research on lawrence horn in the courthouse that day particularly um what
00:13:34.300the status of his child support uh payments were and whatever civil aspects of his ongoing
00:13:42.700uh civil battle with his wife were and he had just been held in contempt several months before
00:13:49.100for failure to pay 18 18 000 in child support but in reviewing more oh that's a clue right there
00:13:56.700he owed some money court records investigators learned that on march 3rd the day of the murders
00:14:03.500horn's financial outlook had brightened considerably with his wife and son dead he now stood to inherit
00:14:11.5801.7 do we know why they died the money came one 1.7 million dollars what was that um yeah his his wife
00:14:20.540and son died yeah oh is this are these is this the wife and son yeah i'm stupid and he said the whole
00:14:29.820time and he just said why oh well it's because there was two dead women and then one son so i was
00:14:35.820wondering if like who if this killer was a random guy or no you're gonna get we're gonna get to that we're
00:14:40.460gonna get to that she's she's another world guys don't worry about that um but yeah so 1.7 million
00:14:47.260dollars guys just so you guys know let me go ahead and show y'all um what 1.7 million dollars in 1993
00:14:53.340would have been today it's um it would have been three million four hundred eighty four thousand
00:15:00.300three hundred sixty four dollars and seventy one cents today guys so that's what 1.7 million dollars
00:15:05.020so that's what he was standing to win um if his if his son passed away and obviously that would be
00:15:10.780split among him and his wife so that each of them would have got like what a 650 000 uh thousand dollars
00:15:17.580back then in 1993 so if she's dead he gets all 1.7 million which in today's buying power is almost
00:15:23.5003.4 million dollars so quick little recap of what's going on here so so far um with there's three dead
00:15:30.460right you got the nurse the mom and the son right uh the son was on a respirator and he was uh it covered
00:15:39.020by some type of insurance that would have given him uh or some kind of lawsuit win that would have
00:15:44.700gotten the family 1.7 million dollars obviously lawrence horn had some issues with his wife they were
00:15:49.180divorced he was a former music uh musician she was an airlines attendant and um they were divorced
00:15:56.140living on opposite sides of the country and um and that's kind of where we're at so far but we don't
00:16:02.780know who the suspect is yet and we're gonna go to 18k and child support and he owed 18 000 in child
00:16:09.020support yes yes thank you mia uh so there's obviously a strong financial motive here so you
00:16:15.420know it's looking like uh the the police might have a solid suspect here but let's see what happens next
00:16:21.740from a malpractice settlement awarded to trevor when a routine operation left him with brain damage
00:16:27.100should trevor die the settlement also listed his beneficiaries the beneficiaries of trevor were
00:16:37.500obviously his mother and his father and that was millie and lawrence if millie were dead lawrence got
00:16:46.220everything at detective wittenberger's request the los angeles police department contacted lawrence
00:16:54.380horn within hours of the murders all right i think you better come out here they tracked him to his
00:17:01.980mother's house mr horn i'm off police told horn about the murders and were surprised by his response
00:17:13.340am i suspect no sir mr horn's behavior was very odd it was odd enough that the lapd officers took note
00:17:22.300of it from the very very outset not only did he not want to cooperate and want to want an attorney
00:17:30.300and that's strange behavior guys your son just got killed and you know you're kind of like oh am i
00:17:36.060a suspect what's going on here basically his only questions or inquiries about were whether he was a suspect in this thing
00:17:44.780police took him to the station for further questions they asked where he was at the time of the crime
00:17:56.220he told them he was with his live-in girlfriend shira boba and described their activities
00:18:03.180later they would question her and she'd corroborate his story
00:18:07.180i was at home if horn or someone he employed it crossed state lines to commit the crime
00:18:14.860they would have violated the interstate travel in aid of racketeering statute
00:18:20.780a federal offense under fbi jurisdiction bam so now that's how you get the feds involved because uh now
00:18:28.860we can articulate if he was actually involved in the crime that there was an effect on interstate uh
00:18:35.260nexus which would allow the feds to be involved because he's in la the crime occurred in maryland
00:18:40.700other side of the country now the fbi was brought in
00:18:49.900a heinous crime had shocked the quiet community of silver spring maryland
00:18:54.380a triple murder that brutally ended the lives of a quadriplegic boy his mother and his overnight nurse
00:19:04.940with the prime suspect 3 000 miles away in los angeles
00:19:08.860the prospect of an interstate investigation
00:19:15.580local detectives called on the fbi okay all right goodbye special agent ed roach
00:19:21.580the case uh immediately became a coast-to-coast uh investigation because so same thing guys case
00:19:30.620agent is the same thing as a case officer so he's going to be the primary uh you know personal
00:19:36.620contact the poc for the bureau uh to help the state do this investigation because as you guys know
00:19:42.140since it's a coast-to-coast investigation well the maryland investigators are kind of limited because
00:19:45.980they don't have the jurisdiction to investigate a crime uh that occurred in los angeles which obviously if
00:19:50.860this does that this did go down it'd be considered a conspiracy uh so that's why the fbi was brought
00:19:56.860in to help out the principal suspect uh was living at that time in in los angeles so uh we involved uh
00:20:05.420the los angeles division of the fbi perhaps uh that we could assist uh later in the investigation
00:20:13.260either uh through uh profiling at quantico or with the assistance of uh the fbi laboratory and profiling
00:20:20.300guys is when they're able to go ahead and identify uh a murder suspect based on characteristics left
00:20:25.180at the crime scene how the murder was perpetrated time of day all these different factors go into
00:20:29.180it so it allows the state and locals to be able to kind of hone in on who was uh more than likely
00:20:34.620the killer in the crime and this especially is used in cases where they go cold or it's difficult to
00:20:39.340identify the suspect um but it's very important to note that the state is still the lead agency on
00:20:45.100this investigation fbi was brought in simply to assist desperate for more clues investigators sent
00:20:53.980a canine team back to where mildred horn's credit cards have been found by a jogger
00:21:00.460the team soon recovered a rusty piece of metal badly corroded
00:21:04.300but clearly a gun part is that a silencer it's uh you'll see here in a second it's not a silencer
00:21:12.940but we are going to get there but look at look at that there there's another clue right here my friends
00:21:19.740wittenberger sent it to the fbi lab for testing
00:21:25.420fbi examiners determined the part was a trigger mechanism from an ar-7 rifle
00:21:30.220a gun that's easy to disassemble into small pieces for transport
00:21:37.420or disposal which seemed exactly what the killer had done efficient yeah
00:21:46.620he had also taken another step to distance himself from the weapon
00:21:50.620he very carefully drilled out the serial number
00:21:55.180oh often a trained examiner can piece these numbers back together
00:22:00.220but this killer had erased another firearms expert would determine how long the gun parted
00:22:13.260lane by the side of the road so quick note on serial numbers guys the reason why it's so important for
00:22:17.900crooks to get rid of serial numbers is because with the serial number you can trace the gun back
00:22:21.580okay thank uh the atf or the alcohol the bureau of alcohol tobacco firearms and explosives they're the
00:22:27.100ones responsible for any time you purchase a firearm you have to fill out some paperwork
00:22:31.180in that paperwork that serial number is in there located on the gun okay it's very difficult to
00:22:35.340drill out and or get rid of and what happens is when you purchase that firearm if that firearms ever
00:22:39.340found on a crime scene or if that's if it's ever discovered or reported stolen whatever it may be
00:22:44.220the feds are able to track it and what they're going to do is let's say they find your gun under
00:22:48.060let's say i buy a gun and they find my gun at a murder scene 10 years prior well they're going to
00:22:52.620later they're going to come back to me say hey you were the one that purchased this gun on such and
00:22:56.940such date where is that where's that gun now or how did that gun end up there and i'm going to be
00:23:01.660like oh well you know i have a bill of sale right hopefully you would have a bill of sale if you sold
00:23:04.860it and i sold this gun on such and such day and then it allows the investigators to have a starting
00:23:09.260point to figure out how that gun got to that crime scene okay so when the serial numbers are drilled
00:23:15.820out and or removed or whatever it is which is a federal crime by the way to scratch out serial numbers
00:23:19.580um they're a it's much tougher for the investigators to go ahead and be able to trace that gun back and
00:23:25.420get a starting point you had something mia no i just didn't know that it was illegal yeah yeah it's
00:23:29.500illegal to scratch out serial numbers on a firearm uh so let's get back to it
00:23:38.140analysis showed the amount of corrosion was consistent with the time elapsed
00:23:42.060since the killings had occurred so this was likely the murder weapon
00:23:49.580while the fbi lab processed the gun part investigators in maryland interviewed tiffany
00:23:58.300horn lawrence and mildred's 18 year old daughter straight ahead
00:24:03.500she was a student at howard university in washington dc
00:24:08.300they gave her a routine polygraph test which she easily passed
00:24:11.660polygraph test by the way guys is simply a lie detector test
00:24:21.020did you commit those murders they're not really doing them anymore right yeah valid yeah they're
00:24:26.700i mean they're not admissible in court uh but they they still do them sometimes some some agencies
00:24:31.980still do them on suspects uh but if i was being investigated for a crime i would never i'd be
00:24:37.180like no i'm not doing it yeah i've read it's more like a psychology trick yeah it actually what it
00:24:41.500does is it um asks it basically when they ask you questions it responds to your biological like uh
00:24:47.020bodily functions i mean in terms of why they still use it even though it's not admissible in court
00:24:51.260like they use it to kind of pressure the the victim but not the victim the person that could be guilty
00:24:56.540yeah into confessing or hey hey you're lying on this test or whatever it gives them it's a basically
00:25:01.820a tool for them to kind of like try to catch you in a lie but yeah it's definitely not admissible in
00:25:05.500court because there's so many people that can beat polygraphs so a lot of crooks beat them all the
00:25:10.060time and a lot of times it's innocent people that fail them psychopaths too because it's based on your
00:25:14.780heart rate exactly yep heart rate sweat um all different types of bodily functions uh are measured on
00:25:22.060the polygraph later that day tiffany would talk with detective wittenberger revealing three key clues
00:25:30.060the first was something that had happened in the summer of 1992 her father had called asking her to
00:25:39.660videotape the outside of her mother's house for him along with trevor's room the idea was so bizarre
00:25:47.020she'd only taped trevor and his nurse with trevor in his bed attached to his respirator tiffany gave the
00:25:54.700tape to her father and you guys got to remember in 1992 that'd be a weird request because you got
00:25:59.820to walk around the big ass camcorder trying to like record the shit you know get on vhs make sure you
00:26:04.860got an empty tape i didn't even think about that you know what i'm saying it's not like nowadays where
00:26:09.180it's like okay sure i'll record a video for you so you could go ahead and you know commit a murder
00:26:13.180down the road no like no now now back then in 1992 it was extremely cumbersome to uh get video footage
00:26:21.420so that's something that would obviously stick out in her memory it's a weird request what are you
00:26:26.300saying an iphone is more traceable now well yeah no yeah an iphone definitely is more traceable now
00:26:31.500destroy the camera if that's it yeah but but again it's just you gotta remember it's a weird request
00:26:36.380that's why she was able to remember it like oh yeah he wanted me to to record the inside
00:26:42.140now wittenberger and the fbi wondered if horn wanted someone to know the layout of the house
00:26:47.580then on march 1st two days before the murders horn had called her again he wanted to know where his
00:26:56.620younger daughter tamiel would be for the next few days another clue
00:27:05.660tiffany said tamiel would be with aunt vivian the night of march 2nd because her mother was flying
00:27:10.700out on an early flight the morning of march 3rd it made investigators suspect that horn had known
00:27:18.060when the murders would occur yep he spared one child
00:27:26.620tiffany shared one other revealing incident
00:27:31.980at about 2 30 the morning of the murders she had inadvertently called her mother
00:27:36.940tiffany had hit the wrong speed dial key on her phone she'd meant to call her boyfriend
00:27:47.100yeah speed dial was a thing in the 90s guys she apologized and hung up
00:27:54.780the timing of the call helped investigators estimate the timing of the murders along with another
00:27:59.980observation trevor's round the clock nurses made entries every hour in a logbook near his bed
00:28:06.940um based on that the 2 30 uh phone call the two o'clock entry in the nurse's log and there
00:28:16.300not being a three o'clock entry uh and the autopsy findings i think we pretty much based
00:28:25.180the time of death as being around two between 2 33 o'clock in the morning so look at all that
00:28:31.340circumstantial evidence guys you know between um him wanting a strange recording of the
00:28:36.700the inside of the house right with the layout um him making sure that his daughter his youngest
00:28:41.180daughter wasn't in the home um the nurse's logbook that showed that uh that was done on every hour
00:28:48.620um and then the final which was um damn it drawing a blank here ladies help me what was the other thing
00:28:54.060that that was also weird just asking where the daughter was going to be the little one yeah there
00:28:59.740was one other thing that he wanted as well hold on it was first it was a video camera yeah i'm
00:29:05.740actually like yeah the video camera yeah and then the daughter uh the daughter and then it was
00:29:12.700oh and then and then the fact that she called late at night right and accidentally was trying to call
00:29:17.980her boyfriend but her mom was awake she called her mom on accident yeah so that was those were the
00:29:23.180those are the things that kind of you know of course each piece of evidence by themselves isn't that
00:29:28.140important but when it's all put together this is strange you know what i mean so it definitely makes
00:29:32.220you get the red flag three o'clock entry uh and the autopsy findings i think on march 11th about a
00:29:42.860week after the murders wittenberger and his partner flew to la with the assistance of the los angeles police
00:29:50.220department they carried a probable cause affidavit to search horns apartment yeah so what they mean by
00:29:57.180that guys is what basically more than likely happened was the detectives in this case from
00:30:02.140maryland said uh got with a detective from los angeles right hey i have this probable cause i need to
00:30:08.380search this residence can you swear to this affidavit for me and get a uh you know a search warrant from
00:30:13.260the judge in your local area because as a maryland officer they don't have the authority and or
00:30:18.060jurisdiction to swear out an affidavit in front of a judge in california so lapd gets involved
00:30:25.100they get the affidavit give it to a judge he signs it boom now they're able to go ahead and
00:30:29.820execute a search warrant in another state a state search warrant
00:30:40.380they collected hundreds of audio videotapes police also gathered computers personal papers
00:30:47.420address books bank statements and telephone logs
00:30:56.940back at the station investigators began the time-consuming task of reviewing all they'd recovered
00:31:05.420they'd printed thousands of pages from the hard drives of horn's computers
00:31:09.260they found he'd made handwritten notes on documents regarding trevor settlement money
00:31:18.300oh another red flag handwritten notes on trevor settlement money the notes confirmed what they
00:31:24.140already suspected horn was well aware he could gain a fortune from his son's death
00:31:29.820and he was well versed in the legalities of the settlement
00:31:37.100investigators also found a map that was telling
00:31:39.820it was hand-drawn showing mildred horn's neighborhood the streets were outlined and labeled
00:31:49.100an ex and her initials marked her house
00:31:51.260more circumstantial evidence because remember guys he's in la why the hell is he drawing a map
00:32:07.820of uh his ex-wife's home videotape that were recovered one home they stood out
00:32:16.780horn had videotaped himself standing in front of his television set which was tuned to the cable tv
00:32:22.380program guide station the station was clearly broadcasting the time and date 11 45 pm march 2nd 1993
00:32:31.900california time 2 45 am march 3rd maryland time exactly the time and date of the murders
00:32:42.940investigators quickly dubbed it the alibi team since it's holy my guy was prepared he totally did that
00:32:50.860yeah he was prepared he had all this stuff in place man but then those papers isn't that kind
00:32:56.940of sloppy having those papers yeah but i think for him he didn't anticipate that they would search his
00:33:01.660home so yeah uh that's funny been created for that purpose
00:33:10.700now wittenberger and the fbi but you got to remember he could always say oh well i took notes
00:33:15.420on it because it was just i needed to know the policy and understand the policy blah blah blah
00:33:19.580like the thing with circumstantial evidence is that it's typically weak on its own and you can easily
00:33:23.980refute it right like in that case oh uh i you know i found that your policy and you had a bunch
00:33:28.540of handwritten notes on it what was that oh well you know he can easily explain well you know i just
00:33:32.060want to kind of know it i wrote some notes asked an attorney you know nothing too crazy but when you
00:33:36.700add the fact that you know he wanted to make sure his daughter wasn't in the house he asked for a
00:33:41.420strange vcr vid from his daughter from his 18 year old daughter of the home he had a map of the home um
00:33:47.740and then you had uh the fact that he did a strange home movie where he um was in front of the tv with the
00:33:53.500day and time saying look where i'm at niggas day and time right here i'm here in la and whatever
00:33:58.300then it starts to look more suspect that's the beauty of circumstantial evidence when uh when you
00:34:02.620know it could be a higher put together somebody what was that could be that he hired somebody
00:34:07.420oh we'll get there we'll get there exactly so we'll see what happens next um but yeah the fact
00:34:13.980that he took all these steps to distance himself are definitely big red flags
00:34:18.700seem to have some substantial leads but they were still far from apprehending the mastermind
