Caitlyn Jenner Will NOT Be Charged With Vehicular Manslaughter Or Any Crime

The L.A. County D.A. will NOT charge Caitlyn Jenner with vehicular manslaughter or any other crime in connection with the fatal car crash on PCH.

The D.A. has rejected the case, saying she was not speeding, she hit the brakes though belatedly, and her conduct was not "unreasonable" based on all the facts.

Jenner was driving inattentively when she slammed into a Lexus, sending the car into oncoming traffic where it struck a Hummer. The Lexus driver died at the scene.

The accident was put under a microscope ... the L.A. County Sheriff's Dept. investigated the accident for almost 6 months before submitting a 161-page report to the D.A. The case was reviewed not by the D.A.'s Van Nuys satellite office -- which would normally handle such cases -- but by the Major Crimes Unit at D.A. headquarters in downtown L.A.

Jenner's lawyer, Blair Berk, tells TMZ, 'We believed from the start that a thorough and objective investigation would clear Caitlyn of any criminal wrongdoing." Berk adds, "We are heartened the District Attorney has agreed that even a misdemeanor charge would not be appropriate."

Berk goes on, "A traffic accident, however devastating and heartbreaking when a life is lost, is not necessarily a criminal matter."
