Justin Lee Gardner was 17 when he was fatally shot at a party at the Stadium Park Apartments in Eugene, Oregon, in the early hours of August 30, 2015.

Investigators identified two people who fired weapons that night. Nineteen-year-old Zachary Beauchamp was arrested and charged; a jury in Lane County later found him guilty of first-degree manslaughter, with the prosecution arguing the shooting was reckless rather than intentional. Another 19-year-old, Sean Edward Jones, was indicted on weapons and related charges, later pleaded guilty to firing six shots during the incident, and received a 15-month prison term in exchange for testifying against Beauchamp. Gardner and Jones had been childhood friends; Gardner and Beauchamp had also been described as friends.

Does anyone have information about Gardner’s activities that night or about the people involved that could shed more light on how the shooting began?
