Unsolved Mysteries: 10 Best Case Theories That Might Be True, According To Reddit
Fans have plenty of theories about what actually happened in the unsolved cases on Unsolved Mysteries, and they aren’t afraid to share them.
Amanda Was Discovered In The Basement By Her Husband, Lee Antoni
Lee Antoni returned from Saskatchewan on August 07, 2025, to discover his wife, Amanda, lying in their basement covered in blood. Lee had been away all weekend, and despite not having heard from Amanda since Saturday night, he did not think anything was wrong. Amanda Antoni’s death was horrifying—many of thedetectives working the case had never seen a scene as gruesomeas the Antoni basement. Given the amount of blood and Amanda’s bashed-in head, detectives concluded that her death was suspicious. The case was assigned to the homicide department despite there being no cause of death attributed to murder.
Why Lee Antoni Was A Suspect In Amanda’s Death
The Spouse Is Always Looked At First
When a death is considered suspicious,detectives always look at the deceased’s partner first. Sometimes, it is blatantly obvious that the partner had nothing to do with the death, but other times, such as in Amanda Antoni’s case, it was not immediately clear. Although theUnsolved Mysteriesepisode begins with Lee Antoni’s hysterical 911 phone call, investigators had to rule him out as a suspect. Lee knew that detectives had to do that to move forward with the investigation, so he did not mind—he just wanted to know what happened to his wife.
Calgary police traced Lee Antoni’s movements from the weekend and determined that he could not have been present at Amanda’s time of death based on his consistent appearances at gas stations from Calgary to Saskatchewan. He was telling the truth when he told the police that he had to go home to Saskatchewan to help his mother put his father’s affairs in order. Investigators believed thatAmanda died around 7:00 p.m. on Saturdaybecause it was the last sign of life from her.

Evidence Suggests Amanda Antoni’s Death Could Have Been Either
Amanda Antoni’s mysterious death was so puzzling that investigators could not determine whether it was an accident or a murder. In fact, anexpert team of behavioral scientists believed that her death was an accidentdespite the very rare likelihood. There was no sign of anyone or anything in the basement other than Amanda herself—all the DNA, footprints, hair, and fingerprints belonged to her. Furthermore, based on the placement of the murder weapon—a ceramic piggy bank—Amanda Antoni could have fallen accidentally, hitting her head on the object, which would have caused her to stumble down the stairs to her death.

Other than a broken right orbital bone and significant bruising, there were no other serious internal injuries.

These circumstances suggest that despite the horrifying scene, Amanda Antoni really did accidentally die.
On the other hand, there isa lot of other significant evidence that suggests Amanda Antoni was murdered—evidence that cannot be ignored.
