DETROIT (AP) — Two Detroit carjackers are back in prison after their victim went online and found they'd been mistakenly released.

Local and federal authorities are pointing fingers at each other. But there's no dispute that Brittany Guerriero is the person who had to get her own justice. The men were free for months until December.

Guerriero tells the Detroit Free Press (http://on.freep.com/2lbM6wU ) that she went online in November and found Kendall Kelly and DeMarcus Catlin had been released from federal prison. They were sent there first because their carjacking convictions in state court violated their probation.

Kelly and Catlin were supposed to go to a Michigan prison last year to serve carjacking sentences. But the U.S. Bureau of Prisons says it wasn't told that the men were supposed to be transferred.
