Los Angeles Police Department officer Nicholas Choung Lee, 40, was killed March 7th in a crash involving a big rig and his patrol vehicle that left a trainee officer and the truck driver in critical condition.

The crash occurred at approximately 8 a.m. at the intersection of Loma Vista Drive and Robert Lane. Authorities said the truck, which was hauling a trash container, was traveling downhill on Loma Vista Drive as the cruiser was traveling uphill. Early reports indicate that the truck driver may have lost control and then hit the cruiser. The truck may have had some kind of mechanical failure, LAPD Chief Charlie Beck said.

Fire-rescue personnel responded to the crash in the Beverly Hills area. Lee, who was assigned to the LAPD Hollywood Division, was pronounced dead at the scene.

A probationary female officer, who recently graduated from the academy and whom Lee had been training for 3 months, suffered a concussion and was hospitalized. The truck driver was also hospitalized and in critical condition. The officers were responding to a call at the time of the crash.

Two rows of officers lined the Beverly Hills street to salute the fallen officer. About 100 uniformed officers and civilian employees lined the street outside the Hollywood Station as the van carrying Lee’s body rolled by.

Lee was a 16 year veteran of the department. He is survived by his wife and two young daughters.
