The officer was riding his motorcycle southbound on Tampa Avenue approaching Chatworth Street when he collided with a car that was attempting to make a U-turn at the intersection, Los Angeles Police Department spokesman Josh Rubenstein said.

The officer was in grave condition following the crash and later died at a local hospital, Officer Norma Eisenman confirmed.

The driver involved in the collision stayed at the scene and was cooperating with investigators, Rubenstein said.

“This appears to be just an awful accident,” Rubenstein said, adding that investigators working at the scene knew the officer.

Los Angeles police Chief Charlie Beck asked for prayers in a tweet about the crash Thursday.

Gasparyan, a traffic collision investigator, is survived by his 6-year-old daughter and his wife, Capt. Andrew Neiman said.

He added that Gasparyan made close to 200 DUI arrests during his time in the traffic division and that he had aspirations to become a motorcycle officer.

"Not only are we going to miss him personally, but professionally, that’s a huge loss for this community," Neiman said.
