On March 8, 2001, Richard Larson, 64, was one of four people found slain inside a Des Moines, Washington, home. His wife Jane Larson, 63, and their grandson Taelor Marks, 17, and Taelor’s girlfriend Josie Peterson, 17, were also killed in the same residence. Investigators identified 19-year-old Leemah Carneh as a suspect; authorities say Carneh had an obsessive interest in Josie Peterson and that jealousy was the apparent motive.

Police allege Carneh first killed Richard and Jane Larson and concealed their bodies, then waited for Taelor and Josie to arrive and killed them. Carneh was arrested four days later; officers recovered blood-spattered clothing, a gun, and items belonging to the victims. Legal proceedings included evaluations of Carneh’s competency and a period of commitment to Western State Hospital before the case moved forward.

Does anyone have information about the victims or the neighborhood around Des Moines in March 2001 that could shed light on the timeline?
