The body of an infant has been found on the coast in the US state of Alabama, near where four children were allegedly thrown off a bridge by their father.
Lam Luong faces four murder charges
Lam Luong, 37, initially confessed to throwing the young children off the Dauphin Island bridge on Monday, but later retracted his confession.
He has now been charged with capital murder, and the search for the bodies of the other children continues.
"Why didn't he kill me instead?" said his wife, Kieu Ngoc Phan, 23.
"It's too much hurting."
The children went missing on Monday
The body of four-month-old Danny was found on Saturday morning by a duck hunter, about five miles (8km) west of the bridge from which the children were allegedly thrown into Mobile Bay.
Divers were searching the area, but called off the operation at nightfall, to be continued on Sunday.
The search has been extended westward towards Pascagoula, across the state border in Mississippi, in the belief that currents might have carried the bodies that far.
"The inevitable nightmare we have feared has now been confirmed," said Mobile County Sheriff Sam Cochran, after the body was found.
"We believe, certainly now, that the father of these children threw these children off the Dauphin Island bridge."
Lam Luong went to the police with his wife to report the children missing on Monday.
Kieu Ngoc Phan had gone with Luong to report her children missing
But when questioned, he said that he threw the children into the water after an argument with Kieu Ngoc Phan. Later, he denied this, insisting that two women had taken the children.
He appeared in court on Thursday, where he was formally charged. If convicted of capital murder, he could face the death penalty or life in prison without parole.
The three younger children - Hannah, 2, Lindsey, 1, and Danny - are Lam Luong's, while the eldest, three-year-old Ryan, is Kieu Ngoc Phan's from an earlier relationship.
Mr Luong came to Alabama from Vietnam in 1984 when he was a teenager and worked as a shrimper.
