David Queen, a 29-year-old African American man, was shot and killed on May 20, 2015, at his apartment complex in Tallahassee, Florida, after a confrontation with 28-year-old Michael Mason. Court records say the dispute began when Mason drove by Queen and another man, yelling from his vehicle; Mason parked near a bank of mailboxes and the argument escalated, ending when Mason shot Queen. Multiple witnesses heard yelling followed by gunshots.

Mason called 911, saying Queen charged at him and tried to grab his keys; someone in the background of the call disputed that account. Police found Queen with a gunshot wound; he was taken to Tallahassee Memorial Hospital and later died. Officers recovered a .22 caliber breech-loaded derringer on Mason and found additional .22 ammunition, a shotgun, and shotgun shells in his vehicle and apartment. Mason showed no signs of a physical altercation and declined to give a statement through his attorney.

The case went to trial where Mason’s defense invoked Florida’s Stand Your Ground law; on November 15, 2017, a jury found him not guilty of second-degree murder. Queen’s mother, Tangela Sears, who had been active in the community, was devastated by his death and the acquittal and later launched a support group called Miami-Dade Parents of Murdered Kids. Does anyone have memories of David or information about the events that night?
