LAS VEGAS- A state trooper was speeding when his cruiser slammed into a car on a freeway, killing four people, police said Tuesday.
It was unclear whether the trooper was pursuing another vehicle or responding to a call when his cruiser crashed "pretty square" into the back of the car Sunday night on Interstate 15, police Capt. Tom Conlin said.
"It doesn't appear that the Ford police car was using lights and siren at the time of the crash," said Conlin, whose department was handling the investigation to avoid having the Highway Patrol investigate a crash involving one of its own officers.
The posted speed limit is 65 mph, but Conlin did not know how fast the cruiser was traveling.
Besides the people killed, the trooper and a 16-year-old girl in the car were injured. She remained in critical condition Tuesday.
Investigators had yet to interview Joshua Corcran, 28, a five-year veteran of the Nevada Highway Patrol. He was treated Monday at a hospital for broken bones, cuts and bruises and released.
Corcran was expected to meet with a lawyer before talking with investigators. He could face vehicular manslaughter charges.
Corcran was on paid medical leave. Toxicology results were pending, although Conlin said it did not appear that alcohol was a factor.
