Summary based on the NamUs case record (MP14069) and 4 other sources
In the early spring of 1987, a young woman named Doris Lavonne Mulhern vanished from Federal Way, Washington, leaving behind a life marked by hardship and constant movement. At 21 years old, Doris, who also went by the names Tina or Doris Lee, was a transient, originally from Michigan. For about two years, she and her boyfriend had been traveling across the country, their lives a blur of changing locations. On a day in early March of that year, this unsettled existence came to an abrupt and mysterious halt. Her boyfriend later told authorities from the King County Sheriff's Office that he had dropped her off at a local mall at approximately 3:00 PM to do some shopping. She was never seen or heard from again. The exact date of her disappearance is uncertain, with reports varying, contributing to the haze of ambiguity that surrounds her case.

Doris was a petite woman, standing at 4'11' and weighing around 105 pounds, with reddish-auburn hair and hazel eyes. A distinctive and painful part of her history was etched onto her body in the form of thick burn scars on her neck, chest, stomach, and arms. When she was last seen, she was wearing a black leather jacket, blue jeans that had the word 'BABY' stitched in pink onto a back pocket, and white tennis shoes. These articles of clothing, along with her physical description, became the last tangible identifiers for a woman who seemed to disappear into thin air from a busy public space. Her life was considered high-risk, and she had a prior arrest record in Colorado. This vulnerability has led to speculation by authorities that she may have fallen victim to a serial killer.

The investigation into Doris Mulhern's disappearance has remained open for decades, a cold case held by the King County Sheriff's Office. Her family in Michigan was left with unanswered questions and enduring grief. Despite the passage of time, the core details of her case remain unchanged. The narrative provided by her boyfriend is the only account of her last known movements, a simple shopping trip that ended in a mystery. Her transient lifestyle made it difficult to retrace her steps or find people who knew her well in the Washington area. The overview of the case is one of profound sadness; a young woman with a difficult past, marked by personal tragedy even before she vanished, simply ceased to be. The few facts available paint a picture of a person living on the margins, whose disappearance left a faint but lasting echo of unresolved loss.
