STRATFORD, Conn. (AP) _ A pickup truck traveling the wrong way on Interstate 95 rammed a small car early Friday, killing all four people in the two vehicles.

The accident occurred just after midnight, when the truck, traveling north in the southbound lanes, crashed head-on into a small Hyundai. The site was near an exit, but police said it was unclear whether the pickup had entered the highway there.

Charles Flaherty, 20, his wife, Josephine, 22, and her 3-year-old daughter, whose name was not immediately released, were traveling from Maine to their home in Fort Bragg, N.C., when their car was struck head-on, state police Sgt. Anthony Schirillo said.

The truck's driver, 41-year-old Silvestre Bonilla of Bridgeport, was also killed.

Tests were planned on the truck driver's body to determine if alcohol or drugs played a role in the accident, police said.
