A New York man is being held without bail after police say he killed his wife and then wheeled her body around before dumping it on the front lawn of a Staten Island home.

Thirty-one-year-old Anthony Lopez pleaded not guilty to a murder charge during an arraignment Sunday in state Supreme Court on Staten Island. The medical examiner's office says 26-year-old Aduba Obiamaka died of ligature strangulation.

District Attorney Michael McMahon says domestic violence may have been a factor in her death.

Police say Lopez fled Friday morning after an off-duty detective saw him wheeling the corpse, covered with a sheet, on Staten Island. He was arrested Saturday in Manhattan after a foot chase.

It wasn't immediately clear if Lopez had an attorney who could comment.
