A Florida man is charged in the fatal crash that killed two children and their father in Divide County.
49-year-old William Koehler of Chiefland is charged with three felony counts of manslaughter in the deaths of 31-year-old Lesley Gunderson and his children, eight-year-old Shelly and two-year-old Shayleigh, all of Noonan.
A third child, four-year-old Shelton, suffered serious injuries in the crash.
Authorities say Koehler was speeding and using his cellphone before he crashed into Gunderson's vehicle from behind.
He is facing 30 years in prison.
