A 27-year-old South Carolina man has been sentenced to 30 years in prison for killing a trick-or-treater who came to his door on Halloween 2008.

Quentin Patrick was sentenced Tuesday after pleading guilty to murder in the death of T.J. Darrisaw.

Prosecutors say the 12-year-old boy was shot at least a dozen times as he stood on the porch of Patrick's home in Sumter. The boy's stepfather and a brother were wounded.

Patrick is a convicted drug dealer and said he fired his AK-47 because he thought a rival drug dealer was back to shoot him again. Patrick has already been sentenced to more than 16 years in federal prison after pleading guilty to being a felon in possession of a weapon.
