ADAMS TWP — A man was arrested after he allegedly shot his 27-year-old son in the lower leg early this morning during a domestic dispute at the family’s home in the 100 block of Cashdollar Road, township police said.

Frank Strutz, 57, and his son were arguing in the garage under the house when the shooting happened about 12:20 a.m., according to investigators.

The defendant was apparently angry in part with the volume that his son was playing heavy metal music when the two clashed, court documents said.

Both men also had been drinking beer all day, said Adams Township police Detective Michael Bailey.

The elder Strutz admitted he fired one or two “warning shots” from his 9 mm Glock pistol out the open garage door before his son grabbed him by the arms.

A subsequent round was fired, hitting Steve Strutz in the left ankle and foot area.

“(The defendant) said that he could have shot (his son) in the head, chest or stomach but didn’t want to because he was his son,” according to a police affidavit.

The gun jammed after the last shot was fired. The suspect told investigators that he and his son resumed fighting and struck one another after the shooting.

The defendant eventually called 911. “The caller said he was attacked by his son and the caller shot his son,” said Steve Bicehouse, director of county emergency services.

Police and other emergency responders arrived and found both men in the garage and “calm,” Bailey said. The defendant was seated on a lawn chair and the victim was seated on a cooler just five feet away.

A Quality Ambulance crew tended to the younger Strutz before taking him to Allegheny General Hospital in Pittsburgh. His condition was not immediately known.

Police recovered the pistol, which contained a magazine clip with 11 rounds in it. A round was jammed in the ejection port.

Officers found the Glock and two other handguns on a lawn mower in the garage. They also recovered two shell casings and a bullet fragment.

Police believe one of the purported warning shots hit the gas tank of a vehicle in the garage.

District Judge Wayne Seibel arraigned Strutz on charges of aggravated assault, simple assault, reckless endangerment and discharging a firearm in an occupied structure.

The defendant, a self-employed machine shop operator, was placed in the Butler County Prison on $10,000 bail following arraignment.

Seibel said that one of the conditions of Strutz’s bail is that he have no contact with his son. Another condition is that he surrender all of his firearms to police.
