NEW ORLEANS - The Louisiana Department of Wildlife and Fisheries says a 5-year-old boy and a 44-year-old man have died in separate boating accidents.

Spokesman Adam Einck says the boy, Ethan Hancock of Houma, drowned under a towboat in the Intracoastal Waterway near Bourg, about 54 miles southwest of New Orleans.

He says Robert Sims of Metairie died when his head hit a piling near Grand Isle.

Einck says Hancock's father's 14-foot boat ran out of gas and he was paddling to shore when the tugboat approached, pushing two barges. Father and son jumped out, afraid the lead barge would hit their boat. The boy's body found nearly eight hours later.

Einck says agents were told Sims was leaning out of a fast-moving 28-foot boat to act as a lookout when his head hit a piling about 1:15 a.m. Sunday.
