Patrice Endres was working at her hair salon in Cummings, GA, on April 15, 2004, when she seemingly disappeared into thin air. Even more perplexing was that there seemed to only be a short window in which she could have vanished, hence the Volume 1 episode title “13 Minutes.” Endres had two appointments that morning, and the second client left the salon at 11:27 am. Another customer called to change an appointment and spoke to Endres on the phone until 11:37 am. When another client called at 11:50 am, no one answered.

The case has many puzzling components. Endres’s car had been moved somewhere different from where she normally parked it, and her keys were still in the salon. By the time the next customer entered the salon for an appointment, no one was there. Police found money missing from the cash register and Endres’s lunch uneaten. People who spoke with her that day recalled her being short or distracted with them, which was unlike her usual demeanor.

In December 2005, Endres’s remains were found behind a church in Dawson County, GA, shifting the focus from where she had gone to who had killed her. She left behind her teenage son, Pistol Black, and her husband, Rob Endres, who was 20 years older than his wife and did not get along with Black. Family friends also said their marriage was troubled.

Focus on Rob Endres heightened after Unsolved Mysteries interviewed him for the Unsolved Mysteries episode on the case. He revealed that he carried his late wife’s skull around and slept with her ashes; he also said that 24 hours after Patrice Endres went missing, he changed the locks on his home and kicked Black out.

Despite many theories, Endres has reportedly been “thoroughly investigated” and has never been charged in connection to the case. Two serial killers were considered as possible culprits, but investigators have determined neither was likely responsible. Police are hopeful that Endres’s wedding ring, which was missing from her remains, will turn up and crack open the case.

Tiffany Valiante was an 18-year-old high school senior living in rural New Jersey in the summer of 2015. After a family party, Valiante walked back home and got into an altercation with a friend about using her credit card. After the friend left, Valiante’s mother confronted her about using the card and went to tell Valiante’s father. In that moment, Valiante vanished from the house. The family’s deer camera showed her walking off into the night, and less than two hours later, Valiante was struck by a train four miles from her home.

By the following day, New Jersey Transit authorities reported that her death was a suicide. Valiante’s family, however, disagreed. The engineers operating the train that night gave conflicting statements about what (if anything) they had seen. Her family also found it suspicious that Valiante was missing much of her clothing, including her shirt, shorts, and shoes.

Frustrated with the lack of investigation, the Valiante family searched through the woods themselves, eventually finding her headband and shoes along the route from her house to the train tracks. They were such a significant distance from the tracks, the family found it unlikely Valiante would have chosen to forgo her shoes and walk on a gravel road for so long, especially without mangling her feet. They also claimed they found an axe with red markings near the scene, but this item was somehow lost.

The Valiante family claims Tiffany was excited to head to college in the fall, where she would play volleyball, and they portrayed her as a happy-go-lucky girl who wouldn’t have taken her own life. They theorize she was picked up by a car near the house and was already deceased when her killer allegedly placed her on the railroad tracks. Some of Valiante’s friends, however, did report that she may not have been as happy as she seemed, and she broke up with her girlfriend shortly before her passing.

The Unsolved Mysteries episode (“Mystery at Mile Marker 45”) also leaves out some additional information pointing to a possible suicide. According to The Daily Beast, prior to the credit card incident the night of her death, Valiante stole money from her parents’ bank account. In 2014, Child Protective Services was called to the home three times, and her mother admitted to punching her in the arm. Valiante had only come out as gay six months prior to her death, which her mother initially called a phase. Friends reported her feeling alienated and lonely before her passing.

Also, conflicting with the theory that a car picked her up, a K-9 unit tracked her scent the entire route from her home to the train tracks.

Friends Carnell Sledge and Kate Brown met up at the Rocky River Reservation, a Cleveland, OH park, around 5 pm on June 4, 2019. Less than twenty minutes after their arrival, they were found by a park bench, both fatally shot.

Though Sledge and Brown had been friends for a decade, no one is sure why they chose to meet up in the park that evening. Sledge’s family said he had plans to go to a dinner at his grandmother’s house (miles in the opposite direction) around the same time, and people close to both victims surmise that one or the other must have had something to discuss.

Despite its occurrence in a heavily trafficked public place during daylight, no one seemed to have heard anything take place, including a roofer who was in his car nearby. (Police say a silencer used on the gun may have prevented this.) Equally baffling is that neither Sledge nor Brown appeared to have any enemies. Authorities aren’t even sure which person (if not both) was the intended target.

As the Volume 5 episode runs through potential suspects, the families discuss the possibility of a random attack or a hate crime. However, Brown’s last cell phone activity occurred at 5:08 pm, leaving only 14 minutes for a crime of happenstance.

While other possible candidates are named – the nearby roofer, Sledge’s sort-of ex, Brown’s sort-of ex, a man Brown went on an alarming date with the Friday before – all of them have solid alibis according to investigators. The “Park Bench Murders” episode ends, frustratingly, with well more questions than answers.

The Volume 3 episode “Body in Bags” opens with the 2018 discovery of a sleeping bag in Ohio along I-75, with something heavy wrapped inside. Police arrived on scene to make a gruesome discovery: Inside was the dismembered lower half of a human body.

Around the same time in Michigan, the family of 39-year-old David Carter was growing concerned about his whereabouts. Carter’s family and friends had last seen him at his son DJ’s football game on Friday, September 28. Carter attended the game with his girlfriend of six months, Tamera “Tammy” Williams (pictured), but things appeared rocky between the pair, and they sat separately.

DJ was supposed to go to his father’s house that Sunday, but texts came from Carter’s phone saying he was sick. DJ went to the house anyway to pick up a few things. When he arrived, he ran into Williams taking out the garbage, but she reportedly ran back into the apartment upon seeing DJ. After this odd interaction, DJ followed her into the apartment to get his things and asked Williams where his father was. She said the allegedly sick Carter was out for a walk.

On October 2, Carter’s family learned he’d missed three days of work and went to his apartment to investigate. They found a blood stain beneath his bed and what appeared to be a bullet hole in his mattress. They filed a missing persons report. Shortly thereafter, Ohio authorities connected the dots from the sleeping bag body to Carter based on a distinctive pit bull tattoo Carter had on his leg.

Investigators and Carter’s family were immediately suspicious of Williams, believing Carter had recently tried to end things. Williams claimed she hadn’t seen Carter since that Sunday but didn’t appear concerned about his whereabouts or involve herself in any initial efforts to find him. Police apprehended Williams on October 5 but released her due to a lack of evidence. Shortly after Williams was released, police found a duffel bag and a suitcase further along the highway with the rest of Carter’s body. He had perished from a gunshot to the head. Meanwhile, Williams had fled.

The US Department of Justice is currently looking for Williams in connection to the case. She was last seen leaving the Neptune Hotel in New York in October 2018. Though she’s described in the episode as a “master of disguise,” a task force investigator said Williams has one distinctive feature: a large tattoo of roses on her left shoulder.

Known as “Buffalo Jim,” James Barrier was a larger-than-life figure in Las Vegas for decades, owning an auto-repair shop where he sometimes worked on celebrity cars, and starting his own wrestling school.

In between Barrier’s shop and school sat a strip club called Crazy Horse Too. The club had long-standing mob ties and was often the subject of police investigations. Since the ’80s, owner Rick Rizzolo and Barrier had butted heads; the latter refused to hand over his portion of property so the club could expand.

On April 5, 2008, according to Barrier’s daughter, Jerica (then a teenager), her father left the house to go to dinner with a friend. He never returned. The following day, Barrier was found dead in a Motel 6 with a white powdery substance on his beard. His death was ruled an accident; high levels of cocaine found in his body were thought to be a contributor to his demise, along with existing heart problems.

But this didn’t sit right with Barrier’s daughters and many of his friends. They alleged he had gotten clean years ago and pointed out that no coke was found anywhere in the room. The motel room had been accessed by a guest key card minutes before Barrier checked in, and his daughters found a voicemail on his phone from a woman named Lisa. Lisa later claimed to have met up with Barrier about selling him a friend’s motorcycle. She claimed she went to the motel with Barrier and then left when he appeared to have a cocaine-induced seizure.

Another odd coincidence was that Crazy Horse Too owner Rizzolo, who had recently been released from prison, was released from house arrest the day before Barrier’s passing. In addition to his own lawsuit against the club owner, Barrier had worked extensively with investigators to help put Rizzolo away.

In her Unsolved Mysteries interview, Barrier’s daughter Jessica said her father had previously told her that if he were to be killed, they’d make it look like an overdose, and there would be women involved. Lisa apparently worked at the Crazy Horse Too. Furthermore, a folded dollar bill was all the money left in Barrier’s wallet, which his daughters say is a known calling card of a mob hit.

In 2002, Joshua Guimond was a 20-year-old college student at St. John’s University in Minnesota who seemed to have a bright future ahead of him. On November 9, Guimond left his apartment with two friends to attend a small poker party a five-minute walk away. After being at the party for about half an hour to an hour, Guimond disappeared. Some attendees thought he was going to the bathroom rather than leaving, as the bathroom and the exit were in the same direction, but regardless, this was the last time anyone definitively saw him.

Guimond’s friends noticed he was missing the following day, and a search ensued. Scent-tracking dogs followed Guimond’s trail for part of his path home from the party, stopping near the campus’s Stumpf Lake. As several similar cases were active at the time – all involving missing young men, alcohol, and bodies of water – many theorized Guimond had somehow ended up in the lake.

In fact, two witnesses walking by the area around the time Guimond left the party recalled seeing someone matching his description pass by, only to turn around shortly after and find he was gone; however, authorities thoroughly searched the lake into the following year and believed Guimond’s body would have floated to the surface in the warmer spring months.

Another piece of evidence that stood out to authorities was that someone had run an internet washing program on Guimond’s computer in the days following his disappearance. This was the only occasion on which it had run. While investigators didn’t have the technology to analyze much in 2002, several years later, they took another look. They found that Guimond seemed to be posing as women on Yahoo Personals and chatting to men.

While they haven’t been able to determine whether or not Guimond ever met up with any of these men, their most promising lead is that his disappearance might be related to his secret online activity.

The Volume 2 episode “Death in Oslo” follows the story of the “Oslo Plaza Woman,” an unidentified woman who was found dead in the Radisson Blu Plaza hotel in Oslo, Norway, on June 3, 1995.

A hotel employee knocked on the room’s door three days after the woman checked in and heard a gunshot. Only 15 minutes later, the woman was discovered deceased in the room from a bullet to the head. Police ruled the death a suicide, but Unsolved Mysteries explores other theories.

The woman checked into the hotel under the fake name “Jennifer Fairgate.” She also registered a guest staying with her, “Lois Fairgate,” and was seen with a man, though there was no evidence another person actually stayed in the room.

There was, however, some suspicious evidence in the room suggesting someone else could have staged the scene. Someone had taken a shower, yet there were no toiletries in the room, only a black briefcase containing bullets. The gun’s serial number had been professionally etched off, and all the clothing tags on the woman’s garments had been removed. She also had no blood on the hand holding the gun, as there usually is in suicides, yet there were blood splatters on the walls.

While key card information showed the woman left the hotel for 20 hours after checking in, where she went during this time is unclear. When she was found, both key cards were inside the room, and the door was double bolted. A window was open, but her room was located on the 28th floor, making this seem a less likely exit point.

A Norwegian intelligence officer featured on the episode, Ola Kaldager, theorizes the Oslo Plaza Woman was actually a secret agent who was executed, saying some of the evidence is akin to common spy cover-up tactics.

Mary Ellen Deener was walking to get change for the laundromat when the 14-year-old was assaulted and killed. A man with an extensive criminal record, Lester Eubanks, confessed to the crime and was sentenced to death row in 1966.

In 1972, Eubanks’s sentence was commuted to life in prison. His good behavior and relationship with the guards at the Ohio prison earned him a spot in a reclamation-to-society program in 1973, where prisoners were allowed to go Christmas shopping unattended in a mall. Eubanks never returned from his temporary furlough.

In the Volume 2 episode “Death Row Fugitive,” Unsolved Mysteries tracks Eubanks’s movements immediately after his escape from Michigan to California (where he was living with a girlfriend under the alias “Victor Young”) to Alabama. Though his trail seemingly went cold by 2003, renewed interest from the series generated an influx of tips.

In 2021, the US Marshals Service announced they believed Eubanks, then age 77, was in the Los Angeles area.

In April 2004, Alonzo Brooks went with some friends to a party in La Cygne, KS, about an hour drive from his hometown. Brooks didn’t know most of the people at the party, which had about 100 guests, but seemed to be having a good time.

One by one, his friends left the party. One friend who was expected to give Brooks a ride home left for cigarettes and got lost, going home instead. He called another friend to arrange a ride home for Brooks, but an apparent miscommunication took place. As referenced in the Volume 1 episode title, “No Ride Home,” Brooks never returned from the party.

Brooks’s family immediately knew something was wrong when he wasn’t home the next morning. Searching the area, they came across his boots and hat on the side of the road; they believed someone tossed them out the window of a moving car. A search ensued in the proceeding days that included the FBI and divers in the nearby creek, but they didn’t locate Brooks.

About a month later, Brooks’s family and friends received permission to conduct a search of the area. In about 30 minutes, they found his body on a pile of brush by the creek.

Brooks’s cause and manner of death were initially listed as “undetermined,” but his family suspected foul play. Local rumors swirled that Brooks had been targeted because of his race. Brooks was reportedly one of three Black men at the party, which took place in a predominantly white, rural area. Some accounts suggested someone might have gotten angry at Brooks for talking to a white girl at the party, or he may have gotten into a physical altercation with other party-goers.

In 2020, police exhumed Brooks’s body to conduct another autopsy. In 2021, they re-classified his case as a homicide.

The Season 3 episode “The Ghost in Apartment 14” is partially narrated by Jodi Foster, a woman who moved into an apartment in Chico, CA, with her daughter on January 31, 2000. Foster describes eerie occurrences in the apartment, such as lights turning off, a doll speaking without batteries, an imaginary presence her young daughter called “My Liz,” and recurring nightmares about a young woman and a couple.

Foster moved out after three months but learned the apartment was formerly inhabited by a young woman named Marie Elizabeth “Marliz” Spannhake, who went missing on January 31, 1976. Spannhake was last seen walking home from a flea market.

In 1984, police got a break in Spannhake’s case when they got a call to the local Church of the Nazarene. A woman named Janice Hooker was deeply troubled by the past acts of her husband, Cameron, and wanted to confess them.

After she was promised immunity, Janice told police she and Cameron had been driving in 1976 when he offered a ride to a young woman (presumably Spannhake). When she later tried to exit the car, Cameron placed a sound-proof box over her head and took her to their home. There, Janice said Cameron attempted to cut Spannhake’s vocal cords so she couldn’t scream, but Spannhake started bleeding heavily. Janice said Cameron took Spannhake to the basement, and when Janice returned downstairs, she was deceased. The couple then drove out to the woods, where Cameron buried her body the same day.

Janice also revealed, however, that Spannhake wasn’t Cameron’s only victim. He abducted another woman in 1977, Colleen Stan, whom he held captive in a coffin-like box for seven years. One day, Janice confided in Stan that she wanted to leave Cameron. The two women escaped the house while Cameron was at work. After fleeing, Stan spoke to family members about what happened but didn’t report it to police at Janice’s request.

Cameron Hooker went to trial in 1984 for Stan’s abduction and was sentenced to 104 years in prison. Without Spannhake’s body, however, investigators were unable to charge him with her murder. According to Kevin Hale on Unsolved Mysteries, Chief Investigator for the Tehama County District Attorney, Cameron has already been granted parole; however, he must undergo mental health evaluations for authorities to determine whether or not he should still be considered a “sexually violent predator.”

Cameron will likely be held at a mental health facility for an undetermined amount of time. Janice Hooker assumed a new name and is raising two children.
