Forty years after her body was discovered along Interstate 81 in Kline Township, a Washington, D.C., teenager has been identified.

But the circumstances surrounding her death remain a mystery.

Gladys T. “Tinker” Johnson’s nude body was found in the woods on the north side of the highway, about two miles south of McAdoo, on April 8, 1986.

She had just turned 18 years old.

Pennsylvania State Police in a news release said she had left home a month before to celebrate her 18th birthday, but never returned home.

Her body bore no signs of violence; a doctor who examined her concluded she died from adverse effects of cocaine.

Authorities buried Johnson in the cemetery at the former Schuylkill County nursing home, Rest Haven, in Schuylkill Haven, on Sept. 5, 1986.

After several years of fruitlessly searching for her identity, police entered Johnson’s information into the National Missing Unidentified Persons Data System.

In 2024, her body was exhumed and sent to the Institute for Forensic Anthropology and Applied Science at the University of South Florida, police said.

A year later, the National Center for Missing and Exploited Children created a digital reconstruction of Johnson’s face and posted it on its Facebook page.

In June 2026, a person contacted the center and said they might be a family member. Genetic testing confirmed a match, and her family was finally able to put her to rest.
