A 24 year old woman is dead following a bizarre traffic accident on the city's northwest side, Newsradio 1200 WOAI reports.

  Police say Priscilla Acosta was a passenger in a Cadillac that was eastbound on the Loop 410 access road, when she and the driver had some sort of an argument.

  Acosta got out of the car at a stoplight, and the driver drove on.

  The driver took the turnaround at Fredericksburg Road, but, unknown to him, Acosta had walked across the main lanes of Loop 410 and was walking down the westbound access road.  The Cadillac hit her and killed her.

  The driver of the Cadillac remained on the scene, but police say he was drunk, and he was charged with intoxication manslaughter.
