Christina Marie Plante: Arizona girl who disappeared at 13 found alive after 32 years; what we know so far

A 13-year-old Arizona girl who mysteriously disappeared without a trace more than three decades ago while walking to a nearby horse stable has been found alive. Christina Marie Plante, the blue-eyed blonde teen who vanished from Star Valley, Arizona, is now 44 the Gila the Gila County Sheriff’s Office has announced, ending a successful resolution of a decades-old missing person case.

According to the Sheriff’s Office, Plante was last seen on May 19, 1994, around 12:30 p.m., after leaving her home in Star Valley on foot to walk to a nearby stable where her horse was kept. Her disappearance was described at the time as “endangered and under suspicious circumstances.”

Authorities have not released details about how she was found but said ‘evolving technology’ played a key role in generating new leads.

Extensive searches for Christina Marie Plante conducted after disappearance

Adam J. Shepherd said in a news release that the girl was reported missing at the time, and "extensive search efforts" involving local and regional resources were conducted. Plante was listed in national missing children databases, and missing persons posters were distributed around the region, state, and country.

"Despite exhaustive ground searches, interviews and investigative follow-up, no viable leads were developed" at the time of her disappearance, Shepherd said, and the case remained open. Over the decades, investigators re-examined evidence and pursued any new information that became available, he said.

Why we know so little about Christina Marie Plante

The sheriff's office later established a cold case unit focused on unresolved investigations. Detectives used "advances in technology, modern investigative techniques and detailed case review" to develop new leads that "ultimately led to a breakthrough," Shepherd said.

Shepherd did not say where Plante was found, or share any circumstances of her disappearance "out of respect for Christina's privacy and well-being." Investigators have confirmed her identity, and her status as a missing person "has been officially resolved."

Shepherd said the case "underscores the importance of cold case review initiatives and the impact of evolving technology in bringing long-awaited answers to families and communities," and said the sheriff's office "remains committed to pursuing all unresolved cases."
