The Indiana State Police superintendent explains the reason for the different sketches.
"I think that was the absolute right decision at the time to do what they did. I've always said that the two sketches are simply sketches. They are not photographs. It's a piece of an investigative puzzle, " said Superintendent Doug Carter.
Allen was recently transferred to state custody for safety reasons. He's due in court in a few weeks.
