The driver of a minivan that struck and killed a man who was standing at a Burbank bus stop Friday night had been stabbed before the crash, police revealed Saturday.

The crash occurred about 5:40 p.m. when a minivan veered off Olive Avenue, jumped the curb and drove down the sidewalk, causing a 52-year-old man to become wedged under the vehicle, Burbank Police officials said.

The victim, identified as Rodolfo Tan, 52, was extricated and taken to a hospital, where he died, police said in a news release Saturday.

The driver of the minivan, who has only been identified as a 33-year-old Glendale man, was treated at the scene and taken to the hospital.

Investigators discovered that the driver had been stabbed in the chest before the crash and was driving at a high-rate of speed when he sideswiped a parked vehicle, crossed the opposite lanes of traffic and crashed into a bus bench.

The man is in critical condition Saturday and authorities have not been able to speak to him. Investigators, however, have spoken to the driver’s family and are working to determine how, when and why the man was stabbed, police said.

He has not been arrested.
