A man accused of throwing his 3-month-old daughter off a New Jersey bridge testified at his murder trial Thursday that the child was already dead when he tossed her into the Raritan River.

The Star-Ledger of Newark reports that Shamsid-Din Abdur-Raheem told jurors Thursday that his infant daughter fell to the floor and hit her head during a tussle he had with the baby's maternal grandmother at the woman's East Orange home on Feb. 16, 2010.

Abdur-Raheem admitted taking the child from the grandmother and fleeing with her in his car down the Garden State Parkway.

Abdur-Raheem says he became upset when he noticed the child wasn't breathing and appeared dead.

He told jurors he was not sure why he then tossed his daughter off the Driscoll Bridge.
