Alyssa Angelique McLemore was 21 and living in Kent, Washington, when she disappeared after receiving a family emergency call on the evening of April 9, 2009. She was a young mother to a three-year-old daughter and cared for her gravely ill mother, Gracie, who died three days later without hearing from her. Alyssa, a member of the Aleut tribe, was described as deeply family-oriented and her disappearance was out of character.

On April 10 investigators recovered a frantic, roughly 10-second 911 call placed from Alyssa’s Blackberry at about 9:15 p.m.; a woman’s voice pleads for help and a male voice in the background can be heard saying something threatening. The phone lacked GPS, and authorities believe the call came from somewhere in the Kent area. Witnesses placed Alyssa near 30th Avenue South and Kent-Des Moines Road the day she vanished, reporting she was approached by or got into a green 1990s pickup truck possibly bearing Oregon plates; one witness described a man with her as a Caucasian in his 50s or 60s. The phone went out of service a few days later and the case remains open.

Anyone who knew Alyssa, was in that Kent area on April 9–10, 2009, or has information about a green pickup or the people seen with her is asked to come forward.
