WEBBERS FALLS, Okla. (AP) -- Tugboat crew members' accounts of the moments before a barge rammed a highway bridge support the theory that the boat's pilot blacked out, an investigator said Tuesday. The accident killed at least seven people whose vehicles plunged from the damaged bridge into the Arkansas River.
George Black of the National Transportation Safety Board said a crewman who visited with captain Joe Dedmon five to 10 minutes before Sunday's accident said everything seemed normal.
"We did get some information from that interview that would tend to agree with the captain's statement that he was incapacitated in some way before the collision," Black said on CBS' "The Early Show."
The other crew members, who were not with Dedmon at the time of the crash, said they heard no alarm or change in the sound of the engine that would indicate he was trying to avoid impact, Black said.
Dedmon, who was to be interviewed later Tuesday, tested negative for drugs.
