Gunman to be sentenced to life in prison

ORLANDO, Fla., Sept. 5 (UPI) -- An Orlando, Fla., man accused in a triple slaying faces life in prison for killing an unarmed 16-year-old boy with an AK-47, prosecutors said.

Marcus Walker, 31, was convicted Friday of one count of first-degree murder in the death of Carlus Patterson, the Orlando (Fla.) Sentinel reported Saturday.

A jury acquitted Walker of two other slayings committed July 30, 2008 in a crowded Orlando apartment.

At least 15 people were in the apartment and at least three other guns were fired, Walker's lawyer, Jeff Dowdy, told jurors.

Walker, who had claimed self-defense, fired the AK-47 in the apartment 28 times, prosecutors said.

Walker's sentencing is set for Wednesday.
