Prosecutors have charged an Oklahoma man with second-degree murder in the death of his disabled 8-year-old son, who was overcome by carbon monoxide last month.

The Tulsa World reports (http://bit.ly/2p17LKA ) that Noel Cruz, of Tulsa, was charged Monday in the death of Noah Cruz Campbell, who had spinal muscular atrophy and used a wheelchair.

According to prosecutors, Cruz was found, passed out but alive, in a running vehicle in a garage adjoining his home. The door to the family's home was left open, allowing fumes from the garage to pollute the home too.

An affidavit says Cruz told authorities he'd left the door open so he could hear if Noah called. The boy died of carbon monoxide poisoning.

Cruz remains jailed on $500,000 bond. Court records don't list an attorney.
