Two years on from the shooting that caused Ronnie's death I am asking for the public's help and information so we can catch the people responsible. Despite extensive investigations we still cannot be certain of the motive behind the shooting that day, but I am confident that Ronnie was not the intended victim.
We know that people's allegiances shift over time and now that two years have passed I need people to come forward and talk to my team and I. Ronnie's family and friends deserve answers about the chain of events that resulted in Ronnie being taken from their lives.
