Gregory Liascos, 36, was arrested for allegedly attempting to break into the Rice Northwest Museum of Rocks and Minerals in Oregon last week while wearing a "moss suit" often favored by military snipers.
According to NBC-2, Hillsboro police believe Liascos spent several nights trying to chisel through a wall and into a bathroom -- perhaps in an attempt to snatch the museum's quarter-million-dollar gold collection.
But investigators say Liascos' plan had several flaws.
First off, the suspect was allegedly drilling into a bathroom that was blocked off from the museum's collection by an elevator shaft.
Secondly, the perp left behind a mess. After spotting mysterious debris on the bathroom floor two days in a row, a museum janitor discovered a hole in the wall. The museum contacted detectives, who installed new security devices.
On Thursday, those alarms went off, alerting police of an attempted break-in.
After deputies discovered a bike and a backpack near the museum, they sent a police dog to search the grounds.
"The K9 tracked to a wooded area and was very interested in a particular piece of ground about a half a mile away from the building," Sgt. David Thompson, a spokesman for the Washington County Sheriff's Office, told The Associated Press. "The dog then bit the ground that in turn cried out in pain."
Liascos -- in his leafy "ghillie" camouflage -- was cuffed and charged with burglary and criminal mischief.
