"It's a very warm and loving community so for a tragedy such as this to happen, we always find it much more difficult and it's knocked everyone for six.
"To happen to such a young person and the alleged perpetrator to be a young person, in the high street at 5pm, is just shocking, everyone is just shocked and struggling to come to terms with it, it will ruin so many lives."
