Runaway Barge Sinks in the Ohio River

Divers are working to pinpoint the location of a runaway barge that sank in the Ohio River near Cairo, Illinois, on Wednesday.

The U.S. Coast Guard said the missing barge is one of six to have broken free from a towing vessel near mile marker 964. The other five barges have been located and secured.

Divers are scheduled to search using side scan sonar.

The sunken barge is carrying a cargo of pig iron.

The Army Corps of Engineers has closed the Olmsted Lock and Dam until the lost barge is located.

The Coast Guard is broadcasting a safety message to notify mariners of the situation.
