A MAN in the US has admitted throwing his four young children from a high-rise bridge into coastal waters after an argument with his wife.
Lam Luong, 37, of Irvington, Alabama, has been charged with four counts of murder.
He was being held in the Mobile County jail awaiting a court appearance today.
Searchers in boats and helicopters were scouring 260 sq km of coastal Alabama waterways for the children, who ranged in age from four months to three years and were presumed dead.
Investigators said Mr Luong first reported the children missing on Monday but later admitted he threw them from the 24m bridge connecting the Alabama mainland to Dauphin Island near Mobile following a dispute with his wife.
"We're doing an extensive search," said Sergeant Jerry Taylor of the County Sheriff's Department.
Seven law enforcement agencies, including the US Coast Guard, joined the search, which resumed at daybreak yesterday after being called off on Tuesday night due to rough water and fog.
Divers were also involved in the search for the bodies of the children, along with boats using sonar.
Police identified the children as four-month-old Danny Luong; Lindsey Luong, 1; Hannah Luong, 2; and three-year-old Ryan Phan.
