KARNS CITY — Two teenage brothers already awaiting trial for attempted homicide face new charges for allegedly vandalizing a church in the borough.

State police on Tuesday charged Jeremiah McGrady, 19, and Zechariah McGrady, 17, both of Fairview Township, with breaking into the Zion Assembly Church of God on Olive Street on Sept. 20.

The brothers opened a back window to get into the building, police said. Once inside, they used markers to write graffiti on the walls, according to court documents. Nothing was taken.

A short time later and on the same street, the teens walked to Adam Bell’s house and broke in through a back door

Bell was home and surprised the intruders, who allegedly assaulted and stabbed the man while his wife and their children were sleeping.

The 34-year-old Bell collapsed after fending off the suspects. He required treatment at a Pittsburgh hospital for injuries including severed arteries, a cut liver and collapsed lung.

On the following day police arrested the brothers for the home invasion.

The brothers in that case, which is pending in Butler County Court, are charged with attempted homicide, aggravated assault, robbery, burglary, theft, simple assault and reckless endangerment.

Jeremiah McGrady remains in the Butler County Prison on $175,000 bail. Zechariah McGrady is being held without bail at a secured juvenile detention facility in eastern Ohio.

Although the younger sibling is a juvenile, due to the charges, county prosecutors charged him as an adult.

The defendants — Jeremiah McGrady in adult court and Zechariah McGrady in juvenile court — are charged in the church break-in with burglary, trespass and vandalizing a place of worship.

Jeremiah McGrady also is awaiting trial on unrelated charges of burglary, theft and criminal mischief stemming from the Aug. 29 break-in of a home on Main Street in Karns City.
