"He was a good kid. He didn't live around here. He came to visit me. He was spending the summer with me and they did that to him for no reason," said his grandmother Desuirea Harris.
The victim's friend says they were walking peacefully in the street around noon on Saturday when the officer started harassing them.
"He just reached his arm out the window and grabbed my friend around the neck, as he was trying to choke my friend, and he was trying to get away, and the officer then reached out and grabbed his arm to pull him into the car," said the victim's friend Dorian.
But St. Louis county police, who have taken over the investigation, are telling a different story.
They are saying it appears the victim acted aggressively toward the officer.
"It is our understanding, at this point in the investigation, that within the police car, there was a struggle for the officer's weapon. There was at least one shot fired in the car. He exited his vehicle, and there was a shooting that occurred when the officer in fact shot the subject," said St. Louis County Police Chief John Belmar.
Police say the officer involved in the shooting is a six-year veteran of the force, and has not been involved in any other incidents like this. He has been put on paid administrative leave.
