Summary
• Advanced DNA testing has officially linked serial killer Arthur Gary Bishop to the 1982 murder of 17-year-old Laura Ann Aime.
• Aime disappeared on Halloween in 1982; her body was discovered by hikers in American Fork Canyon that Thanksgiving.
• While Bishop confessed to the murder before his 1988 execution, forensic evidence has only now provided conclusive proof.
• Investigators used modern DNA technology on a cigarette butt found at the original crime scene to secure the match.
AMERICAN FORK, UTAH — It is a breakthrough decades in the making for a family that has spent more than forty years searching for definitive answers. Tonight, the Utah County Sheriff’s Office is closing a chapter on one of the state’s most haunting cold cases. Using forensic technology that didn’t exist when the crime occurred, investigators have confirmed that 17-year-old Laura Ann Aime was indeed a victim of the notorious serial killer Arthur Gary Bishop.
The details of the case take us back to October 1982, when Laura Ann Aime vanished on Halloween night. The search for the teenager ended in tragedy three weeks later, when her body was found in the rugged terrain of American Fork Canyon on Thanksgiving Day. For years, the case remained a point of intense investigation, eventually crossing paths with the profile of Arthur Gary Bishop.
Bishop, who was executed in 1988 for the murders of five young boys, had previously admitted to killing Aime. However, law enforcement officials say that a confession alone wasn’t enough to officially close the book with scientific certainty. That certainty came recently when investigators revisited physical evidence collected from the canyon more than forty years ago.
The turning point was a single cigarette butt found near Aime’s body. Through the use of modern DNA extraction and testing, forensic teams were able to identify a profile that matched Bishop. This physical link provides the “conclusive proof” that authorities and the Aime family have long sought, bridging the gap between a decades-old confession and forensic fact.
While the man responsible for this horrific crime has long since faced justice, the confirmation brings a necessary, if delayed, sense of closure to the community and the Aime family. The Utah County Sheriff’s Office noted that this development highlights the power of evolving forensic science in ensuring that no victim is forgotten, no matter how much time has passed. For Laura Ann Aime, the truth is finally, officially, on the record.
