Errun Scroggins, 21, was shot and killed during an early morning altercation that began inside the now-closed Martini Ranch bar on Mill Avenue in Tempe, Arizona, on November 28, 2014. The dispute moved outside, gunfire erupted, and Scroggins was struck. He was taken to a nearby hospital but died of his injuries.

Tempe Police investigators ultimately identified three suspects: Franklin L. Russell, 23; his brother Thomas J. Russell, 27; and their acquaintance Edward T. Hall, 25. Witness interviews and evidence led detectives to conclude Franklin Russell fired the shots. All three fled the scene after the shooting and were arrested in the weeks that followed.

What details about that night on Mill Avenue might still help clarify how the confrontation escalated into deadly violence?
