LOS ANGELES, Calif. -

Marlene Pinnock says she thought she was going to die as a California Highway Patrol officer straddled her, repeatedly punching her head, on the side of a Los Angeles freeway.

During an hourlong interview with The Associated Press on Sunday, Pinnock spoke haltingly or in a whisper, occasionally putting her hands to her temples and grimacing.

Her attorney Caree Harper frequently interrupted and limited responses. Harper says Pinnock was released from the hospital last week and slurs her speech because of the beating.

Harper has filed a civil rights lawsuit for the July 1 incident that was caught on now-viral video.

The CHP says she was endangering herself by walking on Interstate 10 and the officer was trying to restrain her. The agency has pledged a rapid investigation.
