On New Year’s Eve 2024, a welfare check in Puyallup, Washington, turned up four dead inside a family home. Thirty-four-year-old Asian female Sue Bin Lee was found in an upstairs bedroom with a contact gunshot wound to the head. Her boyfriend, 33-year-old Shane Vosler, was located in a nearby bathroom with a self-inflicted gunshot wound.

In the garage freezer investigators discovered the decomposing bodies of Shane’s parents, 68-year-old William Vosler and 66-year-old Eileen Vosler. The Pierce County Medical Examiner ruled William’s cause of death as a stab wound to the chest and blunt head trauma, and Eileen’s as multiple stab wounds to the chest and neck; both were homicides. Notes on the refrigerator giving times of death dated July 24 suggest the couple had been deceased since that summer.

Evidence points to Shane Vosler as the suspect in his parents’ killings. The medical examiner left Sue Bin Lee’s manner of death undetermined; investigators reported evidence suggesting a collaborated suicide between Lee and Vosler, but Lee appeared to have died earlier than Vosler. With all principal individuals deceased, authorities say there are no outstanding suspects.

Does anyone have information about the Vosler family or the household during the summer of 2024 that could shed light on what happened?
