Two killed in Lake Worth accident

"It was loud boom and then after that, the car racing took off, whoever hit 'em, the truck or car, whatever it was," says Rosa.

Sheriff's deputies searched for another vehicle overnight, but their search turned up nothing.

"We're still trying to sort through the witness statements, but it appears that physically speaking, there's no other vehicle that's involved in the dynamics of the crash itself," says PBSO Sgt. John Churchill.

Investigators say the vehicle hit a concrete utility pole, rotated around the pole and then came to rest within the eastbound lanes of 6th Avenue South.

Danny Switzer lives near the crash scene.

"I heard like a big crash, you know like hit, somebody hit - like a bad car accident. I didn't see it until I walked out on 6th Avenue," says Switzer.

Switzer says he heard the PBSO Eagle helicopter overhead and watched as deputies worked the scene.

"It's horrible. I couldn't believe it... half the front of the car is missing," says Switzer.

Deputies say the driver and three passengers involved in the crash are all from the Lake Worth area.

"We're going to investigate all aspects and all leads to it, dig in to more depth to make sure that there is no other vehicle involved and if there is, to try to identify the vehicle," says Churchill.

Investigators closed 6th Avenue in both directions overnight, but all lanes opened shortly after daybreak.

By 7:40 a.m., the wrecked car had been removed from the scene and traffic in both directions was back to normal.
