Rashya Long was 17 when she was shot and killed at a New Year’s Day party in Oklahoma City on January 1, 2016. The gathering near Northwest 39th Street and Penn Avenue drew about 100 people; a dispute described as involving rival gang tensions erupted and, as people were leaving, gunfire broke out. Rashya was struck and died at the scene.

Oklahoma City Police identified 21-year-old Kaylin Nicholas Mixon as a suspect. Prosecutors said Mixon, a member of the Sunnyside Bloods, fired into the crowd after feeling disrespected during the altercation. Mixon testified he did not possess a gun that night and fled when shots were fired; a friend’s statement to police implicated him. An Oklahoma County jury found Mixon guilty of second-degree murder and recommended a 30-year sentence; he was sentenced in July 2017.

Did anyone at the party or nearby that night see something that could still shed light on how the shooting started?
