Updated on January 31st, 2021 by Scoot Allan: While the new Unsolved Mysteries on Netflix has introduced a number of new cases that have led to an outpouring of tips and leads, none of the cases have received the iconic "UPDATE" tag that viewers got used to seeing on episodes of the classic series when a case had been solved or viewer's tips had led to further developments. While fans are still waiting for news on some of the newer episodes, there are still quite a few of the creepiest cases from the classic run of Unsolved Mysteries that were solved due to dedicated police work and tips from viewers that showcase the importance of observant and vigilant neighbors and shows that give viewers the opportunity to help with much-needed information.

The "Poisoning" Death Of Ryan Stalling

UNSOLVED MYSTERIES - Patricia Stallings

The third season of Unsolved Mysteries explored the case of infant Ryan Stallings after his mother Patricia rushed him to the hospital, where it was determined he had large amounts of ethyl glycol and ammonia in his system, leading authorities to believe that he was being poisoned. Ryan recovered as the parents were investigated, though after she was left alone with her son during a supervised visit he became sick again and later passed away.

Patricia was convicted of his murder despite her claims of innocence and had another child while incarcerated. This child too started having issues while she was in prison which led to the diagnosis of methylmalonic acidemia that was ultimately proven to have been the reason for Ryan's death, thanks to specialists who came forward after seeing the Unsolved Mysteries episode.

The Freeman/Bible Arson And Murders

UNSOLVED MYSTERIES - Freeman Arson and Murders

A mysterious case of Arson at the Freeman family's mobile home was investigated in the twelfth season episode after the body of Kathy Freeman was found in the debris with a gunshot wound, leading police to believe her husband Danny had killed her and taken her daughter and her friend hostage. However, Danny's murdered body was later found in the rubble by family members.

The mystery deepened due to problems between Danny and the local Sheriff's department, throwing suspicion on to them. Despite a long search, the missing girls were never discovered and the case was unsolved for almost twenty years before Ronnie Dean Busick was arrested and charged after polaroids of the captured girls had been seen that implicated Busick and two deceased accomplices in the drug-related murders.

The Murder of Alie Berrelez

UNSOLVED MYSTERIES - Bloodhounds

Unsolved Mysteries dedicated a segment in the eighth season to exploring the use of bloodhounds in criminal cases and abductions, like the case of the murder of Alie Berrelez, who was taken out of her front yard while her young brother watched after the babysitter went inside for a moment. The bloodhound was able to track her scent for nearly forty city blocks on to a freeway, where searchers tragically discovered the young girl's body.

Despite her brother's identification of the "old man" who took her and the apartment he lived in, no arrests were made despite numerous pieces of circumstantial evidence against the occupant, Nick Stofer. It wasn't until years later that technology advanced far enough for a DNA match to connect the already deceased Stofer to the murder, closing the case without charges.

The Murders Of The Rogers Family

Vampire Cult Murders Of The Wendorfs

UNSOLVED MYSTERIES - Vampire Cult Murder

While the case of the Vampire Cult Murders that appeared during the ninth season of Unsolved Mysteries was in the process of being solved as suspects were already in custody, it's still one of the creepiest cases from the series that was thankfully closed. Rod Ferrell was the leader of a cult that was inspired by vampire stories and games and forced to drink the blood of Ferrell for initiation.

When Rod's friend Heather asked for his help in running away from her parent's home, he entered with an accomplice and bludgeoned them to death before branding him with his assumed vampiric sigil. Ferrell became the youngest person on Death Row for the crime after he was committed following the airing of the episode, though his sentence was later reduced to life in prison.

The Face On Mars

UNSOLVED MYSTERIES - Face on Mars

NASA launched its Viking 1 craft on August 20, 1975. Viking 1's goal: to find out if there's life on Mars. The craft's pods took thousands of compelling Mars photos, including depleted rivers, old volcanoes, and ice caps. The mission also uncovered a strange formation in a desert, a formation that bears a striking resemblance to a face.

Some scientists speculated in a 1989 episode the face was an accident of nature, while others claimed something more was at play – something otherworldly. When a new spacecraft visited Mars in the '90s, updated technologies revealed the Face on Mars is just a hill that looks like a face at certain angles. Unsolved Mysteries retired the file on this case in 1996.

Three months later, a Planned Parenthood in Spokane was bombed while another US Bank was robbed. Eventually, three members of an extreme, far-right religious sect were charged with the bombings in Spokane. When the episode aired in 1997, some commentators speculated the three men were also involved in the Olympics bombing.
