Randy Stevens III, 35, and Constantine Petrovic, 52, both of Falmouth, were pronounced dead at the scene.

Air Care flew Scott Robinson, 34, of London, to University Hospital, where he was in fair condition Friday.

Sandra and Cleon Smith, a married couple from Alexandria, were treated and released at St. Luke Hospital East in Fort Thomas.

A Campbell County police spokesman said Stevens and Robinson were driving south in separate trucks when they collided shortly after 7 p.m. The impact forced Stevens' pickup truck into the northbound lane, where it hit a pickup truck driven by Petrovic. Stevens' pickup then hit the Smith pickup truck that was sitting at a stop sign on Moreland Road.

Robinson's truck eventually landed on its top off to the side of the road, two-tenths of a mile south of Moreland Road.

Campbell County police spokesman Keith Hill said an official cause had not been determined.

"The wreck was of such severity it took us a longer time than usual to figure out what happened," said Hill. "It was spread over such a large area, and the trucks were so mangled we didn't know what we had."

Hill said emergency officials initially didn't even see Robinson's flatbed. Officials from most of the fire and police departments in Campbell County responded.

There were two separate investigations Friday into the wreck.

A team made up of several Campbell County departments was trying to reconstruct the wreck. Hill said the team will have to close the road for one to two hours to take measurements as part of the reconstruction. He didn't have a time or date of that closing.

County police detectives, meanwhile, were looking at what each person was doing before the wreck and trying to determine if a crime had been committed.
