Both were in line when an argument ensued. Hood started texting and pointing to her son while a witness was laughing and encouraging Brown.
The son arrived at the doorway as the argument turned into a fight with Brown punching Hood in the head three times, according to prosecutors. That's when the teen pulled out a firearm and shot the victim in the back.
Brown fled the restaurant, but the teen followed him outside and fired more shots as Hood instructed him to continue shooting and to kill him, prosecutors said.
He was shot twice in the back and later died from his injuries.
After the teen finished shooting, prosecutors say Hood turned her attention to the witness and instructed her son to shoot her. She attempted to grab the gun from her son, but he pushed her off. Both then fled the scene and drove back home.
