00:00So, let's start.
00:01Number 10, the murder solved by a tiny piece of DNA.
00:05For more than 40 years, investigators knew that the same man was responsible for a terrifying series of crimes across
00:12California.
00:13He broke into homes, attacked people while they slept, committed sexual assaults, and eventually murdered multiple victims.
00:20Police collected evidence from crime scenes, including DNA, but for decades that DNA had nowhere to lead them,
00:26the man became known by several names, including the East Area Rapist, the original Night Stalker, and eventually the Golden
00:33State Killer.
00:34The problem was that investigators had DNA from the crimes, but the killer himself had never entered a law enforcement
00:41DNA database.
00:42Traditional searches produced nothing.
00:45Investigators could compare the evidence against known offenders, but the person they were looking for simply wasn't there.
00:50The case stretched across decades, while the identity of the killer remained unknown.
00:55Then, investigators tried something that had rarely been used for a criminal investigation at the time.
01:00Instead of searching for the killer directly, they used a genetic genealogy database to look for people who might be
01:07relatives of whoever had left the DNA at the crime scenes.
01:11That changed the investigation completely.
01:13The genetic information produced relatives rather than a name.
01:17Investigators then built family trees, eliminated people who could not have been responsible, and gradually narrowed the possibilities.
01:24Eventually, their attention turned toward Joseph James D'Angelo, a former police officer living in California.
01:30They still needed direct evidence.
01:33Investigators secretly collected biological material connected to D'Angelo, and compared it with DNA from the original crimes.
01:41The match confirmed what investigators had spent decades trying to establish.
01:45D'Angelo was arrested on April 24, 2018, at the age of 72.
01:49The case became a landmark in forensic genetic genealogy because investigators had effectively used the killer's family tree to find
01:58someone whose own DNA had never appeared in the criminal database.
02:01After decades of dead ends, the breakthrough came from something that had been sitting in evidence for years, a microscopic
02:08biological signature left behind by the person investigators had been hunting all along.
02:13Number 9, the killer who left almost no evidence behind.
02:18In 1978, 61-year-old Carol Bonnet was found stabbed to death inside his apartment in Omaha, Nebraska.
02:25His killer had apparently tried to clean up afterward.
02:28Investigators found fingerprints and palm prints in the bathroom, where they believed the attacker had attempted to wash away blood
02:34and other evidence.
02:36Police also recovered evidence from Bonnet's stolen car after it was eventually found in Illinois.
02:41At the time, investigators did everything they could with the prints.
02:45They searched available fingerprint databases, contacted other agencies, and compared the evidence against potential suspects.
02:52Nothing produced an identification.
02:54The case eventually went cold.
02:56For years, those fingerprints existed as evidence without a name attached to them.
03:00More than three decades later, technology had changed dramatically.
03:03In 2008, an Omaha police laboratory technician decided to run the old prints through the FBI's Integrated Automated Fingerprint Identification
03:13System, known as IAFIS.
03:16The system had not existed when Bonnet was murdered.
03:19Within hours, it returned potential matches.
03:21One candidate stood out.
03:23Jerry Watson, who was already serving a prison sentence in Illinois for burglary.
03:28Investigators went back through the original evidence and discovered another strange connection.
03:32Among the old material was a classified advertisement flyer with the name Jerry W. written on it.
03:38They also found that Watson had lived only a few blocks from where Bonnet's stolen car had been recovered.
03:44There was another problem.
03:45Watson was close to being released from prison.
03:48Investigators traveled to Illinois and obtained a DNA sample from him.
03:53The DNA matched biological evidence recovered from Bonnet's crime scene,
03:57giving investigators a second major piece of evidence against him.
04:01Watson was charged, convicted, and sentenced to life in prison in 2011,
04:06exactly 33 years after Bonnet's body had been discovered.
04:10The strange part of the case was how little had changed in the physical evidence itself.
04:15The fingerprints had been sitting there since 1978.
04:18What changed was the technology capable of reading them.
04:21Number 8.
04:22The crime with no body and no clear motive.
04:25When Kelsey Barrett disappeared in Colorado in November 2018, investigators faced a nightmare.
04:32There was no body, there was no obvious murder weapon, and there was no straightforward explanation for what had happened
04:39to her.
04:39Barrett was a 29-year-old flight instructor who was last seen alive on Thanksgiving Day.
04:45She was supposed to meet her fiancé, Patrick Frazee, later that day.
04:48Instead, she disappeared.
04:50The investigation quickly became focused on Frazee, but proving a murder without a body created an enormous problem.
04:57There was no corpse to examine, no confirmed cause of death,
05:01and no conventional crime scene containing the kind of evidence investigators normally depend on.
05:07Then, investigators found something crucial inside Barrett's home.
05:11Surveillance footage showed a woman entering the house around the time of the disappearance.
05:15That woman was Crystal Lee, a nurse who had been having a relationship with Frazee.
05:20She eventually told investigators that Frazee had planned Barrett's murder and described what happened inside the home.
05:27Her testimony gave investigators a narrative for a crime that had almost no physical evidence of a victim's body.
05:33Prosecutors also presented surveillance footage, phone records, and other evidence that they said connected Frazee to the disappearance.
05:41Lee described Frazee's alleged plan to dispose of Barrett's body, while investigators worked to piece together what had happened after
05:49Barrett vanished.
05:50The defense repeatedly pointed to the missing body, missing murder weapon, and lack of an obvious motive.
05:56Prosecutors countered with the accumulated evidence and Lee's testimony.
06:00In November 2019, Frazee was convicted of murdering Barrett and sentenced to life in prison without parole.
06:07Plus, an additional 156 years, Barrett's body has never been recovered.
06:13The case became a striking example of how a murder prosecution can move forward even when investigators never find the
06:21victim.
06:21The physical evidence was incomplete, the body was missing, and the circumstances were deeply uncertain at the beginning.
06:28What eventually gave the case shape was a combination of surveillance footage, digital evidence, and the testimony of someone who
06:35claimed to have been involved in the plot.
06:37Number 7.
06:38The mystery solved by a 100-year-old fingerprint.
06:42In 1905, a woman named Mary McElroy was murdered in Kansas City, Missouri.
06:47The investigation was conducted at a time when fingerprint identification was still in its early stages, and investigators had very
06:55limited forensic technology compared with what police departments use today.
07:00Decades later, investigators were still dealing with the consequences of old, unsolved cases.
07:05One of the most remarkable developments in forensic history came when previously collected fingerprints from old crime scenes could be
07:12examined again using much more advanced identification systems.
07:15Fingerprints have an unusual advantage over many other forms of evidence.
07:20The patterns on a person's fingers remain remarkably stable throughout their life.
07:25A print that was nearly useless to investigators generations ago can potentially become valuable once technology improves.
07:33This principle has helped reopen cases that seemed permanently lost.
07:37Old fingerprints can be digitized, enhanced, and compared against enormous databases containing millions of prints.
07:45Someone who was completely unknown when the crime happened may eventually appear in the system because of a later arrest.
07:53That is exactly why old evidence can become unexpectedly important.
07:58A fingerprint doesn't become outdated simply because the investigation does.
08:02The technology surrounding it changes in several historic investigations.
08:07Prints collected decades earlier have eventually produced matches after suspects entered fingerprint databases for unrelated crimes.
08:14Investigators can then go back to the original case and compare the old evidence with the new identification.
08:20The most unsettling part is how little the physical evidence itself needs to change.
08:24A fingerprint can sit inside an evidence file for decades, waiting for the right technology and the right database to
08:31make sense of it.
08:32For investigators working cold cases, that possibility can completely change the value of evidence that once appeared useless.
08:38Number six, the murder solved by a forgotten photograph.
08:42In 1969, a young woman named Jane Britton was found murdered in her apartment in Cambridge, Massachusetts.
08:50Britton was a 23-year-old Harvard graduate student whose death initially left investigators with very few answers.
08:57The investigation eventually stalled.
09:00Years passed, then decades.
09:02The people who had originally worked on the case grew older or retired, while the evidence remained buried in police
09:09files.
09:10Then, an unexpected piece of information helped bring the investigation back to life.
09:15An old photograph.
09:17Photographs can preserve details that investigators may overlook when they are first taken.
09:22A person in the background, a vehicle, a sign, or even the position of an object can become important once
09:28investigators understand more about a case.
09:31That happened repeatedly in cold case investigations as detectives began re-examining photographs with modern technology.
09:38Images could be enlarged, enhanced, and compared with records that didn't exist when the original investigation took place.
09:45In Britton's case, investigators eventually determined that the murder had been committed by a man who had connections to the
09:52area and had been questioned during the original investigation.
09:57The case remained unresolved for years while detectives continued examining old information and trying to establish what had actually happened.
10:05The investigation eventually led authorities to Kenneth M. McDonald, who was identified through renewed examination of the evidence and investigation
10:16surrounding the case.
10:17Cases like this reveal one of the biggest problems with old investigations.
10:22Investigators only understand evidence through the information available to them at the time.
10:27A photograph taken in 1969 might look completely ordinary.
10:31Decades later, after databases have expanded and investigators have learned more about the people involved, the exact same image can
10:39take on a completely different meaning.
10:41That is why photographs from old crime scenes can be so valuable.
10:45They freeze an investigation in time, preserving details that everyone at the scene may have overlooked.
10:50Number five, the crime that took decades to connect.
10:54For years, authorities investigating murders in several American states had no reason to believe they were connected.
11:00Different victims, different locations, different years, the cases were investigated separately, and without modern DNA technology, there was little available
11:10to connect them.
11:11Then, forensic testing began revealing something investigators had been unable to see before.
11:16Biological evidence from different crime scenes belonged to the same person.
11:21One of the most significant examples involved the murders committed by Samuel Little.
11:26Little traveled extensively across the United States, attacking vulnerable women over a period of decades.
11:33Many of the deaths were initially classified as accidental, overdoses, or remained unsolved.
11:39With victims spread across different states and investigations conducted by different police departments, the crimes were incredibly difficult to connect.
11:47Little was eventually arrested in 2012 after investigators connected him to a murder in Texas through DNA evidence.
11:54He was convicted in 2014, but the investigation did not end there.
11:59Detectives continued questioning him about other killings.
12:03Little began confessing to murders across the country, describing victims and locations in remarkable detail.
12:10Investigators then compared his statements with old case files and physical evidence.
12:15The FBI ultimately determined that Little had confessed to 93 murders, and authorities were able to confirm his involvement in
12:22dozens of cases.
12:23The agency considers him the most prolific serial killer in U.S. history.
12:28What made the investigation so difficult was the passage of time.
12:31Each murder existed as its own mystery, sometimes for decades, until DNA evidence and new investigative work began connecting them.
12:42Suddenly, cases that had appeared unrelated started forming a single pattern.
12:46For investigators, the breakthrough wasn't simply identifying one murderer.
12:51It was discovering that a large number of supposedly isolated crimes had been committed by the same person.
12:56Number four.
12:57The killer identified by a single strange detail.
13:01In 1977, a young woman named Barbara Oberholzer disappeared while hitchhiking near Breckenridge, Colorado.
13:08Her body was found months later, and investigators quickly realized they were dealing with a murder.
13:13But there was very little that could identify the person responsible.
13:17Another woman, Annette Schnee, had disappeared in the same area around the same time.
13:23For decades, the two cases remained separate mysteries.
13:26Then, investigators noticed something unusual.
13:29A small piece of evidence recovered from Oberholzer's case eventually became important.
13:34A distinctive red fiber found on her body.
13:37Advances in forensic science allowed investigators to examine evidence that had been difficult to interpret when the murders occurred.
13:44The investigation eventually focused on Alan Lee Phillips, a truck driver who had been in the area at the time.
13:52Investigators were able to connect him to both women through a combination of witness accounts, vehicle information, and newly analyzed
14:01forensic evidence.
14:02Phillips was arrested in 2021, more than 40 years after the women disappeared.
14:08The case had survived for so long because the evidence available in the 1970s could not provide investigators with a
14:14clear suspect.
14:15Decades later, detectives could combine old records with forensic techniques that simply hadn't existed when the murders occurred.
14:22A tiny piece of material that had once seemed almost meaningless became part of the chain that finally led investigators
14:29to a suspect.
14:30Number 3.
14:31The case where the main suspect had already disappeared.
14:34In 1986, 18-year-old Michelle Schofield was found murdered in Florida.
14:40She had been stabbed, and her body was discovered near a highway.
14:44Investigators eventually focused on her husband, Leo Schofield.
14:47The evidence against him appeared convincing enough that he was convicted and sentenced to life in prison.
14:53But there was a problem.
14:55Another man had been seen near the location around the time of the murder, and questions about the investigation continued
15:01for years.
15:02Schofield maintained that he was innocent, while his family continued trying to reopen the case.
15:08Decades later, investigators began re-examining the physical evidence using modern DNA testing.
15:14DNA recovered from the victim's clothing did not match Schofield.
15:19The testing eventually pointed toward a different man, Jeremy Scott, who was already serving a prison sentence for another crime.
15:26Scott had never been the person investigators originally convicted for Michelle's murder.
15:31By the time the case was being seriously reconsidered, decades had passed.
15:35In 2023, a judge vacated Schofield's conviction, and he was released after spending roughly 35 years in prison for a
15:44murder.
15:44He maintained he did not commit.
15:46The case demonstrated how difficult an investigation can become when the original suspect appears to fit the evidence,
15:53and the actual killer remains outside the investigation.
15:56The person responsible was effectively invisible to the original case.
16:00By the time modern forensic testing provided a different direction, the investigation had already consumed most of a man's life.
16:08Number two, the crime solved by evidence nobody thought mattered.
16:11In 1989, 11-year-old Jacob Wetterling disappeared while riding his bicycle home in Minnesota.
16:18The disappearance became one of the most famous missing child cases in American history.
16:22For nearly 27 years, investigators had no confirmed answer about what had happened to him.
16:28Thousands of tips were investigated.
16:29The case generated enormous public attention, but Jacob's fate remained unknown.
16:34The breakthrough eventually came from an unexpected source, an unrelated investigation into another man.
16:40In 2016, Danny Heinrich confessed to abducting and killing Jacob.
16:45Investigators had previously questioned Heinrich during the original investigation,
16:49but there had not been enough evidence to charge him.
16:51What ultimately helped connect Heinrich to the crime was information and evidence collected over the years during the investigation,
16:59including details that had initially seemed unrelated to Jacob's disappearance.
17:04Heinrich eventually led investigators to Jacob's remains, ending nearly three decades of uncertainty for his family.
17:10The case illustrates how enormous cold case investigations can become.
17:15Evidence can be collected, cataloged, and preserved for years without revealing its importance.
17:20A clue that seems insignificant at one stage can become critical after investigators discover a new suspect or a new
17:27connection.
17:28Jacob's case remained unsolved for so long that an entire generation grew up without knowing what had happened to him.
17:35The answer finally came from an investigation that had taken years to develop,
17:40connecting, information gathered at different points in time, until investigators could finally establish what had happened.
17:48Number one, the crime that was solved years later by a hidden connection.
17:52In 1976, 18-year-old Arliss Perry was found murdered inside Stanford Memorial Church on the Stanford University campus.
18:00She had gone to the church alone to pray, and when her body was discovered, investigators were faced with a
18:06bizarre crime scene and almost no obvious explanation for what had happened.
18:10The investigation continued for years, but identifying the killer proved extremely difficult.
18:16Investigators eventually developed a suspect, Stephen Crawford, a Stanford security guard who had been working around the campus at the
18:23time.
18:23But there wasn't enough evidence to make an arrest.
18:26The case remained open for decades.
18:28Then, in 2018, investigators returned to evidence that had been preserved from the original crime scene.
18:35Advances in DNA analysis allowed them to test material that investigators in 1976 could not analyze in the same way.
18:44The results pointed toward Crawford.
18:46Investigators obtained additional DNA evidence from him and compared it with material recovered from the crime scene.
18:52The results provided the connection they had been missing for more than four decades.
18:56Crawford was 72 years old when investigators confronted him at his home.
19:00Before he could be arrested, he died by suicide.
19:03The case had remained unresolved for 42 years.
19:06The suspect had been living his life while the investigation slowly became one of the oldest unsolved murders connected to
19:11Stanford.
19:12What finally changed the case was the ability to extract useful genetic information from evidence that had been collected when
19:18DNA testing was still in its infancy.
19:21For investigators, the lesson was practical.
19:23An old crime scene can contain evidence that hasn't become useless simply because the case is old.
19:28Technology can change what investigators are capable of learning from material that has been sitting untouched for decades.
19:35In Arliss Perry's case, the person investigators eventually identified had been on their radar before.
19:39The missing piece was the forensic connection that could turn suspicion into evidence.
19:44More than four decades after the murder, that connection finally emerged.
