In the early morning hours of August 14, 2010, a first wedding anniversary celebration at the City Grill restaurant in downtown Buffalo ended in a mass shooting. An argument inside the restaurant escalated and a gunman opened fire as patrons were leaving; ten shots were fired in about 17 seconds. Four people died at the scene, including 35-year-old Robert Dumas, and four others were wounded. A fifth victim, Demario Vass, later died from his injuries.

Investigators initially faced uncooperative witnesses among the more than one hundred people present, and an incorrect arrest was made in the immediate aftermath. Attention shifted to 23-year-old Riccardo McCray, who surrendered to a local television station 11 days after the shooting and denied being the shooter. At trial, surveillance footage and witness testimony tied McCray to the attack; a jury convicted him on multiple counts of murder and attempted murder and weapons possession, and he was sentenced to life in prison without parole.

Did anyone at the anniversary party or nearby that night see something that could still help clarify what happened?
