The feds are having trouble keeping a convicted Portland man in custody. 

Logan Storm has been convicted of possession of child pornography but U.S. marshals don't know where he is. 

U.S. Attorney Amanda Marshall says the first time Storm took off was after his home and computer were searched. "Within 24 hours of serving that search warrant Mr. Storm left the country, drove to Canada, boarded a plane and flew to London.  He then spent the next nine months in western European countries.  He was eventually convinced to return to the United States an turn himself in on the indictment."

Then this week Storm was convicted.

A judge said he could stay out of jail until his April sentencing as long as he wore a monitoring bracelet.

Now, he's slipped the bracelet and vanished.

He does not have a passport but authorities don't know if his family or friends may be helping him. 

Storm may be driving a green F-150 Ford pick up with the Oregon license plate 726-CKA.
