KEY WEST, Fla. (AP) - A Delaware man and his 11-year-old son had to be hospitalized after being run over by their charter boat's propellers while diving in the Florida Keys.
    
Florida Fish and Wildlife Conservation Commission spokesman Bobby Dube tells the Key West Citizen that 39-year-old Calvin Adkins of Harrington, Del., and his son were airlifted to Miami hospitals in serious condition after Tuesday's accident.
    
Dube says Adkins and his son were run over by their 46-foot charter boat just after getting into the water near Conch Reef, 9 miles south of Key Largo. It was unclear whether they jumped in before the boat's captain and crew told them to.
    
The Coast Guard, state wildlife officials and the Monroe County Sheriff's Office are investigating.
