His killer is still at large.
One concerned Lowedges resident said: "I've lived in Lowedges for 28 years now and I can't believe this has happened.
"I was watching TV last night but I didn't hear a thing until the police helicopter came out. I didn't know the boy personally but I've said all things like god bless him because that's the type of people we are, so young it's terrible."
Another said: "It's made me feel like I want to get to get my kids off these streets, what is the world coming to?
"I can't believe he was only 15, it's no age. It was only the other week someone got stabbed down Batemoor too."
