Francisco Daniel Arriaga, a 25-year-old Hispanic/Latino man, was shot and killed outside the Bum Steer nightclub on North Stone Avenue in Tucson on June 12, 2005. Arriaga was standing in the lot talking on his cell phone when he was struck twice by gunfire and collapsed.

Investigators recovered a nine-millimeter handgun near the club. Ballistic testing showed at least one bullet removed from Arriaga had been fired from that gun, and DNA from the gun’s slide and grip matched Vernon Lee Bullock Jr. Bullock admitted on video to being in the lot that night and to firing a gun, saying he discarded the weapon afterward. He was arrested, tried twice, convicted of second-degree murder and given a 20-year sentence after juries rejected his claim of self-defense.

Did anyone who was at the Bum Steer parking lot that night or who knew Francisco come forward with information then or afterward?
