An Arizona girl who vanished at age 13 under what authorities once called “suspicious circumstances” has been found alive more than three decades later — closing a decades-old cold case while raising new questions about where she’s been and what really happened.
The Gila County Sheriff’s Office announced this week that Christina “Tina” Marie Plante, who disappeared from Star Valley, Arizona, in 1994, has been located and identified after 32 years. Authorities say she is alive and her case is now officially resolved.
But beyond that, investigators are saying very little.
According to the original missing person bulletin, Plante was last seen around 12:30 p.m. on May 15, 1994, leaving her home on Moonlight Drive in Star Valley on foot. She told others she was heading to a nearby stable where her horse was kept, but she never arrived.

At the time, authorities classified her case as “missing/endangered” under suspicious circumstances, signaling concern that she may have been in danger or the victim of foul play.
She was described as having blue eyes and dark blonde hair and was last seen wearing a white T-shirt, multicolored shorts and black tennis shoes.

For years, Plante’s case remained open, periodically reviewed by investigators and preserved in national missing persons databases.
The sheriff’s office credits the eventual breakthrough to the formation of a Cold Case Unit and advances in modern investigative techniques.

While the outcome is rare and remarkable, officials are withholding nearly all details about what happened during the decades she was missing. The sheriff’s office has not said where Plante has been since 1994, whether her disappearance involved a crime or how investigators ultimately located her.
“Out of respect for Christina’s privacy and well-being, additional details will not be released at this time,” the agency said.
Authorities emphasized that the case’s resolution underscores the importance of cold case investigations and evolving technology in generating new leads, even decades later. Officials are encouraging anyone with information about other unresolved cases to come forward.
