Local divers who have been working 16 hour shifts are getting some relief. The FBI and US Navy have sent dive teams to Minneapolis to help in the recovery effort. The Hennepin County Sheriff says at least seven to nine people remained missing from Wednesday’s bridge collapse. Meanwhile state officials have been given the green light to start removing debris from the site. Investigators first wanted to thoroughly document the scene. On Monday, the National Transportation Safety Board used a helicopter equipped with a high resolution camera to take pictures of the wreckage.
