SUNBURY -- City resident William Brown doesn't think twice when he sees an emergency unfolding before his eyes.

Brown helped rescue a 1-year-old girl who was strapped in a car seat in a vehicle driven by a man who had passed out after he overdosed Tuesday on Fentanyl, police said.

"A man was slumped over in the driver's seat and there was a bunch of people standing around the car," Brown said, recalling the scene he witnessed in the Weis Markets parking lot at 1100 N. Fourth St. as he left the YMCA.

James Fyler, 28, of Sunbury, had driven to the pharmacy with the infant to pick up his wife's Fentanyl prescription. Fentanyl is a powerful painkiller.

Instead of returning home with the prescription, Fyler injected the drug while inside the vehicle immediately after leaving the pharmacy, city police alleged.

Fyler was unconscious, apparently with his foot on the brake, when Brown, a volunteer firefighter in Upper Augusta Township, approached to find the doors locked and the car's automatic transmission in drive.

He had a passing motorist block Fyler's vehicle to prevent it from moving, and he was able to put a hand through a partially opened window and unlock the doors.

Brown put the transmission in park and checked on the occupants.

"I just wanted to make sure the baby was all right," Brown said in a telephone interview.

The infant was babbling to herself and appeared content, he said, and Fyler was passed out, but alive.

"I checked for a pulse and made sure his airway wasn't blocked," Brown said.

He then stepped away from the vehicle and let the police and emergency medical technicians take over.

Police found a burned spoon, syringe and several prescriptions for a person they did not identify.

After Fyler was treated at Sunbury Community Hospital, he was arraigned by District Judge Carl B. Rice on misdemeanor charges of endangering the welfare of a child, recklessly endangering another person and possession of drug paraphernalia.

He is being held in lieu of $30,000 cash bail at Northumberland County Prison pending a preliminary hearing.
