Many in Laquan McDonald's life recall a jokester who could make them laugh until they cried, a kid who liked to give everyone a hug. They nicknamed him "Bun Bun" back when he was a chubby little boy. By his teenage years, he had grown slim and tall, at 6-foot-2, and liked to rap. He had tattoos on each of his hands, one reading "Good Son" and the other a pair of dice and the acronym "YOLO" — "You only live once."
