Federal authorities to review Georgia high school student's mysterious death

When 17 year old Kendrick Johnson died last January, his body was found in a rolled up gym mat. Local authorities ruled his death a tragic accident, but his parents have maintained he was murdered. Now federal authorities say they will investigate the case. The announcement came one day after a judge granted Johnson's family access to new evidence. Victor Blackwell has been following this story and has the latest on all of these developments.
