Sergeant Kenneth Gary Vann Sr., 48, was killed on the night of May 28, 2011, while on duty with the Bexar County Sheriff’s Office. He was responding to a non-emergency call when, at a red light on Rigsby Avenue, a vehicle pulled alongside his patrol car and the occupant opened fire. Vann was struck multiple times and died before reaching the hospital. The weapon used was an AK-47 rifle.

Vann was a U.S. Marine Corps veteran who had served with the sheriff’s office for more than 24 years. He is survived by his wife, who also serves with the sheriff’s office, and three children. The shooter, identified as Mark Anthony Gonzales, fled but was arrested about a week later during a raid on his home; reports state Gonzales was later found guilty of capital murder and sentenced to death on October 20, 2015.

Does anyone have information about Sergeant Vann’s final assignment or remember the area around Rigsby Avenue that night?
