A Chevy Chase man has been charged with making and possessing destructive devices after his girlfriend's father found pipe bombs in his duffle bag.
Kyle G. Druckemiller, 19, was charged with two counts of knowingly manufacturing, transporting and possessing a destructive device by a Montgomery County grand jury Thursday afternoon.
Investigators say the father of Druckemiller's girlfriend discovered the bombs on April 12 after checking a duffle bag that Druckemiller had brought with him while he visited his girlfriend.
It's unclear what Druckemiller intended to do with the bombs, though investigators say he claimed he learned to make them on YouTube.
According to court documents, the father had grown suspicious of Druckemiller after he had found a loaded gun in Druckemiller's coat several weeks ago. On a picture on his Twitter account, Druckemiller is seen posing with a rifle.
When police responded to the home in April, they found two pipes, one with end caps blown off and the other with end caps still on and a hole for a fuse. They also found two timers and an improvised detonator.
The court documents say Druckenmiller had traveled to South Carolina to buy fireworks to make the pipe bombs, and while he was there one of the pipes exploded.
Since that incident, he had kept the pipe bombs in his duffle bag, according to the documents.
The charges carry a penalty of up to 25 years in prison and a $250,000 fine.
"Today's Grand Jury indictment reflects the seriousness of the crime," said Ramon Korionoff, a spokesman dor the Montgomery County state's attorney, in a statement.
"In light of the tragic events in Boston we must be ever vigilant to protect our residents," he said.
