SAN ANTONIO — San Antonio Police said a driver was killed after slamming into an SAPD patrol car and spinning into a nearby tree on the city's southwest side Thursday night.

The driver has been identified as 31-year-old Jonathan Smith.

Shortly after 11 pm Thursday, a Ford F-150 driven by Smith was traveling at a high speed going southbound on Tupper Avenue, according to police.

Investigators said Smith ran a stop sign and slammed into an SAPD squad car which was traveling west on Southcross Boulevard.

The crash caused the squad car carrying Officer Jesus Aguirre, to spin out of control and slam into a utility pole.

The truck ricocheted into a nearby tree in someone's front yard. Smith was transported to University Hospital where he was pronounced dead.

Officer Aguirre walked away uninjured.
