Details of Disappearance

Marable was last seen in Yakima, Washington at 9:30 p.m. on April 23, 1991. She had gone out with friends to the Sports Center Tavern. The bartender saw her getting into a maroon pickup, which he recognized as owned by Bill Robinson. She has never been heard from again.

According to her sister, Marable got involved with drugs after she graduated nursing school, and wound up losing her nursing career and custody of her daughter due to drug abuse. By the time of her disappearance, she was a street prostitute. She was abducted and raped by a stranger in 1990, and suffered from anxiety after the attack. The parking lot where she was last seen was the same lot she was abducted from.

The attacker, John Robinson, was convicted of first-degree rape and kidnapping in Marable's case. During his sentencing in the spring of 1991, he threatened her and her family in open court. Marable disappeared a few weeks later.

John was civilly committed as a sexually violent predator after his release from prison. He was released from the commitment center in February 2019 and went to live in the Tacoma, Washington area, but was returned to the center a few months later after violating the terms of his release.

John was in jail at the time of Susan's disappearance, but it's worth noting that it was his brother Bill's pickup truck that Susan was seen getting into on the night of her disappearance. The police never interviewed Bill about Marable's disappearance, and he died in 1992.

Marable last saw her family in February 1991. She was acting uneasy and told her family she wanted to turn her life around. Foul play is suspected in her disappearance, but there have been no solid leads in her case in decades.
