Austin Wayne Howse was 16 when he was shot dead on the night of July 27, 2011, while sitting in a vehicle on Mira Loma Drive in Colorado Springs. Two other teenagers in the same car, brothers Wayne Dylan Fix, 19, and Aaron William Fix, 16, were also killed.

Investigators concluded the shooting arose from a roadway disturbance between a vehicle carrying the teens and a car driven by 24-year-old Michael Arangio. Police identified Arangio as the suspect, saying they found no other connection between him and the victims and warning he was considered armed and dangerous.

A manhunt ended a few days later when officers located Arangio at his apartment complex, the Resort at University Park. After a five-hour standoff with negotiators, Arangio died of a self-inflicted gunshot wound. The families were left with unanswered questions about the specific events that led to the killings.
