Three men suspected in the death of a DeKalb County man are in custody, a sheriff’s spokeswoman said.

Antonio Wilson, 18, and Adonis Lewis, 17, of Decatur and Braindon Cayo of Conyers allegedly shot and killed Tre Griffin in November in Stone Mountain, spokeswoman Cynthia Williams said.

Griffin was killed during an armed robbery, according to warrants that charged the suspects with felony murder and armed robbery.

Wednesday, deputies arrested Wilson at a DeKalb high school and Lewis at a Decatur residence, Williams said.

It is not known at which high school Wilson was arrested.

Cayo was arrested in Murfreesboro, Tenn., on Tuesday and is being held on local charges after he tried to escape. He will be housed there pending extradition.
