On the evening of July 4, 2016, a party at a residence in the 2000 block of East 36th Street in Tucson ended in fatal violence when 28-year-old Thomas Barnes was shot. Witnesses say an altercation at the gathering escalated after Barnes reportedly used a stun gun on 29-year-old Glenn Kyser. Kyser then pulled a handgun and shot Barnes.

Officers arriving about 6:15 p.m. found Barnes lying in front of the house with gunshot wounds; he was taken to a hospital and later pronounced dead. Tucson Police investigated and arrested Glenn Kyser, who was booked into the Pima County Jail on a charge of second-degree murder.

Barnes was remembered by people who knew him as kindhearted and always smiling; he had worked at Five Guys and attended Marina High and Apollo schools. Does anyone who was at the July 4 gathering or who knew Thomas have information that could help clarify what happened that night?
