  • February 18th, 2016, 2:30 p.m.: A 34-year-old man walking on Broadway was allegedly asked by Smith "where Columbus was. The victim told him and Smith replied asking for $50 dollars. The victim said no and Smith threatened to shoot him. Smith then forcibly removed the victim's wallet from his pants and fled."
