The Starkville Daily News says Kewon Delarryous Doss was found guilty this week in Oktibbeha County Circuit Court. In addition to the prison term, Doss was also ordered to pay a $1,200 fine and $4,890 in restitution.
Doss was charged with killing 38-year-old Larry Davis, his uncle, in January.
Authorities say the shooting happened at a house the men shared. Deputies say Davis died from a single gunshot wound to the torso.
