As I begin work alongside dedicated colleagues and homicide investigators, my thoughts and sympathies are with this man’s family and friends. I can assure them of our total commitment to finding whoever was responsible and bringing them to justice. “I am appealing for any witnesses who are yet to speak with police to make contact with us and share what they saw or anything that they know.
