The California Highway patrol is investigating a collision where a Waterford teenager was killed when a Turlock man ran a red light.

The deceased has been identified as 17-year-old Daniel Casillas, who was driving a 2008 Ford Mustang at the time of the collision.

The collision from June 16 also left Ivan Gomez, 17, of Waterford with minor injuries and 13-year-old Ricky Chavez, 13, of Waterford with moderate injuries, according to the CHP.

The driver of the 2004 Lexus that struck the three teens was identified as Matthew Sullivan, 40, of Turlock. Sullivan sustained major injuries in the crash and was transported to Doctors Medical Center for treatment, according to the CHP.

The collision happened shortly before 10 p.m. at the intersection of Geer Road and Yosemite Boulevard.

Casillas was driving the Mustang westbound on Yosemite Boulevard approaching the Geer Road intersection at an estimated speed of 50 mph. At the same time Sullivan was driving northbound on Geer road at approximately 55 to 60 mph.

The CHP reported the traffic light for the Yosemite traffic turned green and the Mustang entered the intersection. For an unknown reason, Sullivan entered the intersection on a solid red traffic light.

The front of the Lexus struck the driver’s door of the Mustang. The impact sent the vehicle colliding into a metal pole on the passenger’s side.

Casillas was transported to Memorial Medical Center, where he died from his injuries. Gomez and Chavez were both transported to Memorial Medical Center for treatment.

The CHP has said alcohol and drugs did not appear to be factors in the collision. The investigation remains ongoing and at this point no arrest has been made or citation issued.
