The father of a man killed in a State Route 52 crash arrived to the scene and broke down as law enforcement officers investigated what caused the crash.
A 23-year-old man, identified as Tyler De Guide-Rickard, died when his Toyota 4Runner crashed into a big rig on Mast Boulevard near SR-52, according to San Diego Police.
The tractor trailer was traveling eastbound on Mast Boulevard when it approached the westbound ramps of State Route 52.
San Diego Police said a Toyota 4Runner was traveling at a high rate of speed on the exit ramp of SR-52.
De Guide-Rickard failed to stop for a red light, police said, and his vehicle struck the big rig.
At one point, firefighters tried to rescue the victim from the SUV but realized they could not save him.
The victim's father arrived to the intersection and broke down in tears after police informed him that his son died in the crash. According to the San Diego County Medical Examiner's office, the victim lived with his parents in their Spring Valley home.
SDPD investigators say they believe the driver of the Toyota may have been on his way to work at the time of the crash.
The driver of the semi truck was not hurt in the crash but was visibly shaken.
Investigators told NBC 7 San Diego there is video evidence of the collision from the semi truck's dash cam and they are working with the truck company to review the footage.
