Authorities are awaiting notification of family before releasing the names of two people killed late Saturday night on Shoal Creek.
A third person was injured.
Lauderdale County Coroner Butch Tucker said this morning the names of those killed have not been released because they are from out of state and authorities still are trying to contact their relatives.
The injured man is Ross Wooten, of Florence, Tucker said. He said Wooten was taken to North Alabama Medical Center and transferred to Huntsville Hospital, where he is in critical condition.
The crash involved a large cabin cruiser and another boat, Tucker said. It occurred shortly before 11 p.m.
George Grabryan, director of the Lauderdale County Emergency Management Agency, said the crash occurred on Shoal Creek, between the bridge and mouth of the Tennessee River.
Grabryan said the Alabama Law Enforcement Agency is in charge of the investigation.
He said the Alabama Law Enforcement Agency, Lauderdale EMA, Lauderdale County Sheriff's Office, Killen Police and fire departments, Florence Police, and Shoals Ambulance responded to the scene.
Tucker said no one on the large boat was injured, and there was a fourth person on the smaller boat who was not injured.
Tucker said the victims died from the trauma caused by the wreck.
