Multnomah County Sheriff's Deputies are searching for a man they said stole tools, two safes and valuable coins from a shed at a Corbett home belonging to his own father.
Deputies said Dan Johnson, Jr., along with two other suspects, broke into the outbuildings on Christmas.
The safes had approximately 50 to 60 lbs. of silver and jewelry inside, detectives said.
They also contained a coin collection worth several thousand dollars.
Investigators told FOX 12 that the suspects dumped the collection into a coin counting machine in Gresham and received about $450 in return.
"The obvious answer that the crooks were idiots, just simply an idiot," said Dan Johnson, Sr. "To not know the value of what they had taken, just to get pocket change for it. Just really a stupid person. Makes me feel good he was a stupid person and didn't realize what he had."
