Authorities say 13 soda bottle bombs were found in the parking lot of a Hagerstown church and two 11-year-old were apprehended in connection with the bombs.
The Maryland Fire Marshal's Office says a neighbor of the Church of Jesus Christ of Latter-day Saints noticed 10 detonated devices on Saturday.
Fire Marshal's Office spokesman Bruce Bouch tells The Herald-Mail of Hagerstown that three of the devices were determined to be safe, and the remains of all were collected for evaluation.
Bouch says children can find out how to make the bombs from the Internet, and they do not realize that the devices are illegal and dangerous. He says it does not appear there was any malicious intent.
Neighbors also believe the two 11-year-olds meant no harm to the church.
But some members of the Mormon congregation fear sinister forces.
"We have had some vandalism we've had a some windows broken out and it's happened at three of our buildings," says Newman Pauley, Mormon Church facilities manager.
Two Mormon churches in West Virginia and his church got hit with vandalism in the past few weeks.
Pauley thinks it might have to do with presidential candidate Mitt Romney's Mormon faith.
"With the election going on and what have you we have that as a concern," he says. "We have had pretty much of an increase of vandalism nationwide."
