A body has been found in the Ohio River in Kentucky a week after a boat collided with a barge, authorities said.

Louisville Metropolitan Police spokesman Dwight Mitchell said the body found Saturday about 30 miles from shore has not been identified, news outlets reported.

Seven people were on the pleasure craft when the accident occurred April 17 near a boat dock in Louisville.

Hayden Spencer, 20, of Louisville, was killed and four others were injured. A seventh person remains missing.

A cause of death for Spencer has not been released. The accident, which remains under investigation by the U.S. Coast Guard, occurred at the end of the Thunder Over Louisville fireworks.
