Acclaimed director of "Boyz in the Hood" John Singleton was involved in a fatal accident Thursday night in Los Angeles. LAPD officers tell TMZ Singleton was driving his 2001 Lexus SUV around 8:00 p.m. on a Los Angeles street when a female pedestrian, not in a crosswalk, suddenly stepped out in front of Singleton's car. Police say Singleton immediately stopped and waited for police and ambulances to arrive. The woman, 57-year-old Constance Russell, was taken to a nearby hospital where she unfortunately died Friday morning.

Police tells TMZ that Singleton was not speeding at the time and was not under the influence of alcohol or drugs. Cops say their investigation has concluded and they've determined that this is "a very, very unfortunate accident."

Singleton will not be cited for any violation.
