The unfinished Wayne County Jail project.
RELATED: Ficano stopped by FOX 2 to discuss his reaction at the investigation coming to a close. See the video above.
Andy Arena, the former head of the Detroit FBI office says even though Ficano won't be facing charges, he is still responsible for the mess he left behind.
"There's felony and then there's felony-stupid," said Arena, the executive director of the Detroit Crime Commission. "There's criminal activity and then there's ineptness. I'm not really sure all of this falls out."
Arena led the FBI's Detroit office when the investigation began more than three years ago.
"There were like five indictments in the fist six months of the case," Arena said. "That led me to believe that it was going to roll on."
