Guillermo Olivencia, a 61-year-old Hispanic man, was shot to death on April 26, 2015, outside an Advance Auto Parts on North Main Street in Kissimmee, Florida. Police were called about 9:30 p.m.; officers found Olivencia unresponsive in the driver’s seat of his green Saturn with two gunshot wounds to the head. Investigators recovered two .25-caliber shell casings behind the driver’s seat, and determined the shots were fired at extremely close range.

Surveillance video from nearby businesses showed a car with two men parking near the store and a man exiting the passenger side to walk toward the front of the shop. Audio from a camera recorded two pops, and the man was seen running back to the car. Authorities arrested Jason Simmons, 31, and Jonanthony Santiago, 23; Santiago identified Simmons as the shooter and said the two had met Olivencia earlier that day after seeking help with their car. Both were charged with first-degree murder and conspiracy to commit murder and held without bond.

Does anyone have information about Olivencia’s last hours at the store or about people who may have seen the vehicle that night?
