Seventeen-year-old Jeffery Shane Elliott collapsed on the side of the road near the boat ramp in the 6500 Block of South Lagoon Drive. He was found just after sunrise Wednesday.
He was taken to a local hospital in critical condition with injuries deputies believe came from an assault. He died Friday afternoon.
Bay County sheriff's deputies say they're waiting for the results of an autopsy, but they are sure foul play was involved.
The teenager had obviously been severely beaten and deputies are asking for the public's help in solving the case.
Anyone with any kind of information that could be relevant to the case is asked to call the Crimestoppers Tips-Line at 785-TIPS.
