Helen Oliver said her son died the way he lived -- trying to look out for others.
"He's done it before," she said quietly, "and he doesn't like to see anyone intimidated or bullied."
Artwon Oliver, 16, was shot and killed Saturday night after a large group of young men approached a smaller group near Cain Park.
Oliver's brother, Keshawn, said the gang was upset because one of the kids hanging out with Artwon was thought to be a police snitch.
Keshawn said his brother had stepped in to try to make peace when he was shot.
"The bullet was not meant for him at all," Kershawn said, "and I don't think he should be shot for no reason at all."
Cleveland Heights police arrested a juvenile and three men under the age of twenty in connection with the shooting.
"The whole situation is tragic," said Police Chief Jeffrey Roberston.
Authorities identified the men who have been arrested as Dominque King, 19, and Jamal Cammack, 18, both of Cleveland, and Antonio Kirk, 18, of Euclid.
Helen Oliver said her son had a big smile and was loved by many people.
Softly she added, "He will be missed."
