A Philadelphia man accused of speeding, swerving in and out of lanes, and blinking his lights at cars in front of him was charged with vehicular homicide in the death of a woman in a head-on collision on I-95.

Enrico Crispo, 38, was speeding north on Sept. 21 in Middletown Township, Bucks County, when he drove his car into the back of a sport-utility vehicle in heavy traffic, got around it, and then slammed on his brakes, police said. Authorities said the vehicle swerved to avoid hitting Crispo's car, went out of control, crossed the median, and crashed into a southbound vehicle driven by Zera Parker, 58, of Philadelphia.

Parker was killed, and the driver of the vehicle that crossed the median was treated for a fractured lower back and other injuries, police said.

Crispo was arraigned Thursday before Magisterial District Judge John Kelly and charged with vehicular homicide and related counts. He waived a preliminary hearing. His attorney, Richard Fink, declined to comment. - AP
