LOUISVILLE, Ky. » The Louisville Police Department says investigators believe they have recovered the body of one of the three people who remain missing after a pontoon boat capsized in the Ohio River over the weekend.

Police say a family walking along the river near the Falls of the Ohio Monday night found the body and called authorities.

Capt. Joel DeMoss tells TV station WLKY authorities believe it was likely a man involved in the accident.

Jefferson County Deputy Coroner Jack Arnold says he expects to identify the victim by Tuesday.

Missing are Danal Swinney, 36; his girlfriend, Joyce Wright, 37; and his 10-year-old daughter, called "We-We."

Officials say nine people were aboard the boat to watch Fourth of July fireworks when it capsized Saturday. One adult and one child died. Four people were rescued.
