We now know the identity of a man fatally shot by police on State Highway 195 near Mountain Creek Road just south of Killeen late last week, and the details about the incident are disturbing to say the least.

KWTX's Kathleen Serie reports that 39-year-old Alva Gwinn, a Master Sargeant posted at Fort Hood, was just weeks away from being tried on charges of aggravated sexual assault of a child. Gwinn was charged in June 2016 for the rape of a 13-year-old girl that reportedly took place on Nov, 4, 2012 in Killeen.

Gwinn was scheduled to go to trial on Nov. 6th at a state district court in Belton.

Last Thursday’s incident began when an officer responded to a call about a potentially suicidal person in Williamson County around 1 PM. When the officer approached Gwinn’s vehicle, Gwin sped away and led deputies on a chase along Highway 195 into Bell County. DPS Sgt. David Roberts said the chase came to an end near Mountain Creek Road south of Killeen when officers managed to disable Gwinn’s vehicle.

Gwinn reportedly fled the vehicle and pointed a weapon at officers, who opened fire. However, Sgt. Roberts told KWTX it was later determined that Gwinn died as a result of a self-inflicted shot to the head.

A deputy involved in the incident has been placed on administrative leave, and Texas Rangers are investigating.
