Case Description

Any updates on this case? Let us know!
Summary based on the NamUs case record (MP1364) and 17 other sources
Debra Lee Frost, a 17-year-old from Salt Lake City, Utah, disappeared on July 9, 1984. She was last seen at the Mountain Bell Plaza, where her boyfriend worked. That evening, Debra mentioned that she intended to either walk or hitchhike home to Montgomery Street, but she never arrived. Known to be a habitual hitchhiker, Debra had run away before, but she had always stayed with friends. None of her friends or family heard from her after that night.

In the years following her disappearance, there were significant developments, including a report from 2012 that linked Debra to an encounter with police in Rock Springs, Wyoming, 12 days after she vanished. Although police records from that time have been destroyed, it's believed Debra may have been traveling with Fred Martinez, a man she knew. Martinez, who died by suicide in 1995, is considered a person of interest in her case. He allegedly had a romantic interest in Debra, though she did not reciprocate, and was said to have once joked about killing her. Despite this, authorities have not named him as a suspect.

Debra's family, especially her brother Frank Frost, continues to seek answers. Although her father passed away in 2005 without knowing what happened, her family remains determined to uncover the truth. Despite the challenges, Debra's case is still classified as unsolved, and authorities continue to appeal for any information that could lead to a breakthrough.
