Unsolved Mysteries: Breaking Down Each Case Featured in Season 1 of Netflix's Revival

While working at her hair salon, north Georgia hairdresser Patrice Endres vanished — was likely abducted — within a 13-minute time span on April 15, 2004. Her food had been microwaved and money had been taken out of her cash register. Her keys were still present, but her car had been moved from its usual spot. Exactly 600 days after she disappeared, her remains were discovered in the woods behind Lebanon Baptist Church.

Convicted serial killer Jeremy Jones confessed to the murder, but his claim has been discredited. Her body was found 70 miles away from where he said he murdered her, and he didn't give specific details other than the information that was on the news. Endres's friends and son believe that her husband Rob may have had something to do with her disappearance given her unhappiness with the marriage. Rob has brushed off their suspicions and investigators did not think his timeline matched her case.

Endres's case remains open. Her wedding ring is notably missing, and the Georgia Bureau of Investigation has been interested in its whereabouts.

The Dupont de Ligonnès murder mystery is perhaps the most unsettling case featured in the reboot. On April 21, 2011, the police made a disturbing discovery underneath the terrace of the Dupont de Ligonnès home in Nantes, France: the dead bodies of Agnès Dupont de Ligonnès, her four children, and their two family dogs. The children had been given sleeping pills, and each person was shot several times in the head. The person missing from this picture was Xavier, the husband and father.

While Xavier Dupont de Ligonnès left no biological evidence, it's likely he committed the tragic killings. He had sent letters to loved ones saying that he was a secret agent moving to America with his family. Shortly before the massacre, he had also inherited a .22 rifle from his father and bought a silencer. Weeks before the bodies were discovered, Dupont de Ligonnès travelled throughout southern France. He was last seen in Roquebrune-sur-Argens, where he abandoned his car at a hotel.

While the police believe he committed suicide in the backcountry, a friend and journalist featured episode three believe that he may have left for Latin America, as his English and Spanish are good. It's been an unsettling decade for the case. In 2015, someone sent a Nantes journalist a photograph of two Dupont de Ligonnès children, writing "I am still alive" on the back and signing as Xavier. Over the years, bodies have been found and lookalikes have been spotted, but none of them were Xavier.

In 2004, 23-year-old Alonzo Brooks never returned home after attending a party just outside rural La Cygne, Kansas. While he had gone with a friend, the friend had gotten lost after driving around for cigarettes — he told Alonzo to go home with another friend. The next day, Alonzo's family grew concerned that he had not come home. Soon, they discovered his hat and boots by the farmhouse where the party took place.

A month later, his family and friends found his body in a creek near the farmhouse after organising a search party. No cause of death was ever determined, but his family believe that his death was racially motivated — Brooks was one of three Black people at the predominantly white party. Witnesses reported racial slurs, threats, and fights targeted at Brooks the night of his disappearance. There were even rumours that people resented Brooks's presence at the party.

The FBI is investigating the case as a "potential racially motivated crime." There is now a $100,000 reward being offered for information in connection with Brooks's death.

On Sept. 1, 1969, a handful of residents in Berkshire County believed they sighted a UFO. Episode five features testimonies from several residents, including Jane Green, Thom Reed, Tom Warner, Nancy Reed, Jane Shaw, and Melanie Kirchdorfer. Green saw a giant object with bright lights while driving back to Great Barrington. Warner oddly ran outside of a friend's house, where a beam from the sky flashed onto him. Shaw, his friend's sister, said he disappeared for a few minutes. Kirchdorfer had just gotten ice cream when her family saw a bright light from the sky at Lake Mansfield — she recalled levitating and being on a ship — Warner said he saw her there as well.

Thom Reed, one of the most vocal witnesses, was driving with his mother (Nancy), brother, and grandmother across Sheffield Bridge when a bright light came from the Housatonic River. Reed recalls fragments of his time outside the car, while his mother could not account for the lost time. When they were in the car again, his grandma and mother were in different spots. Three hours passed by.

People inundated a local radio station to report unusual lights and loud noises. In 2015, the Great Barrington Historical Society officially recognised the 1969 encounter as a historical event because of all the independent reports. A granite marker was placed in Sheffield to commemorate the event. However, it has since been removed by the town of Sheffield.

In 2006, Dent County resident Lena (Liehnia) Chapin went missing, several years after confessing on tape that her mother Sandy had killed her stepfather Gary McCullough. Gary went missing in 1999, and people had always assumed that he was murdered. Years later, Lena went to Albert, Gary's brother, to confess what she had seen her mother and Kris Klemp, her new boyfriend, do.

According to Lena's taped confession, her mom shot her stepfather in the head while he was eating scrambled eggs. Then, Sandy and Kris wrapped up Gary's body, burned it, and scattered the bones and ashes everywhere. His body was never found. Without any evidence other than Lena's confession, Gary's family couldn't do anything. Sandy lawyered up, and Lena didn't say anything further.

However, the McCulloughs eventually filed a lawsuit against Sandy and Kris for Gary's wrongful death, alleging that Lena was an accessory to murder. The idea here was that Lena could be granted immunity given that she testified for McCulloughs. However, Lena was missing. Sandy said that she had left her son Colter and went to Florida to be with another man. This raised red flags for everyone.

Sandy's other daughters testified against her. The jury awarded Gary's family $7 million. Sandy eventually remarried and now has custody of Lena's son. Lena's sisters believe that her body may be somewhere on one of Sandy's properties, but Lena has yet to be found.
