Gang members pulled up in a car and asked Shaw if he was in a gang. Shaw didn't have time to tell them "no." He was mowed down before he could answer, police say.
His dad heard the shots from inside his house and immediately called his son's cell phone to warn him to stay away. But within seconds, the father realized what had happened.
"I just ran down there," Jamiel Shaw Sr. told CNN.
His son was wearing the same shirt his dad had pressed for him that morning. "He was laying on the ground and his face was so peaceful. I knew he was dead."
"For three hours, I was just completely blacked out walking."
More than 7,500 miles away, Army Sgt. Anita Shaw was serving her second tour in Iraq. Her commanding officer called her into his office and told her to sit down next to the chaplain. He then informed her that her son had been killed on the streets of LA.
"I freaked out," she said. "I wanted to run out of the room. I was screaming and kicking. I was shouting, 'No.'"
Anita Shaw is now back in Los Angeles to bury her son. Hundreds of family members and friends are expected to attend the funeral Tuesday for Shaw, a standout running back and sprinter at Los Angeles High School who had good grades and stayed out of trouble despite his rough neighborhood. Among the schools recruiting him was Stanford University.
"He was a Christian and I thank God for that because I know he's in a better place," his mom said, trembling as she sobbed. "He'd just try all the time to do the right thing. He was so good."
