Headline Goes Here

DAYTONA BEACH, Fla. - A mentally disabled man has been convicted of fatally shooting his adoptive father in central Florida.

A Volusia County jury found 23-year-old Marcus White guilty of manslaughter Wednesday. The Daytona Beach News-journal reports that White faces up to 30 years in prison, but the judge could give him less.

Authorities say White fatality shot his sleeping father, Douglas White, in June 2011 in the family's camper near New Smyrna Beach. Prosecutors say Marcus White changed his story several times when questioned about why he was using his father's .40-caliber handgun, which he was not supposed to handle.

White's attorney said he suffers from autism and fetal alcohol exposure, with the mental function of a young teen. The attorney argued that the shooting was an accident, which is why White called 911.
