DALLAS (AP) A Dallas man who was living with his girlfriend and her toddler son has been accused of punching the boy in the stomach and the child later died.

Dallas police say Clezel Montague Mughni was arrested Wednesday on a charge of injury to a child causing serious bodily injury. Jail records don't list an attorney for Mughni, who's held without bond.

Emergency personnel Monday answered a call about an unresponsive 14-month-old child at an apartment. Marquis Johnson was pronounced dead at a hospital. An autopsy determined he suffered blunt force trauma.

An arrest affidavit says Mughni told police that in the past couple of weeks he punched the boy in the stomach and spanked him a few times for whining. Police list the offense date as sometime since May 1.
