Both parents were revived by paramedics.

Johnson admitted to police that he was using heroin, according to a police report. He was handcuffed and placed in a police cruiser.

Officers found a white residue on a chair, which was collected and sent for analysis, according to the report.

Marshall was transported to Atrium Medical Center because she would not wake up, police said. After she became conscious, she was transported to the Middletown City Jail.

The situation could have been “10 times worse,” Muterspaw said. “Anybody should be appalled.”

Officers brought the young boy and infant back to the police department after the incident. The boy was given a badge “for being so brave,” according to police.

Muterspaw called the boy “a little hero,” adding that it was dark and he was barefoot when he left the house.

Muterspaw said doesn’t understand why a parent with children at home would ever use heroin.

“(The children) are first,” he said. “You are not first.”

Johnson and Marshall were both charged with two counts of endangering children and disorderly conduct.

Each are being held on $7,500 bond in the Middletown City Jail.
