It went eastbound on Patterson after it left the park."Following the shooting, police officers, friends, and loved ones gathered at the hospital.Philadelphia Police Commissioner Richard Ross was seen leaving the hospital after consoling the victim's father.

Our hearts are broken and we're keeping him and his family in our thoughts and prayers. It's just another example of senseless violence," Commissioner Ross said. "We have no reason to believe at this juncture that Nicholas Flacco had anything to do with the fight. He was just along with some of the people there."On Sunday morning, officers were back at FDR Park investigating."It's a sad thing, it's a senseless thing. Somebody saw what happened there. Somebody should come forward. You bring them in today, you're paid today," FOP president John McNesby saidFlacco was a student at Penn State University's main campus. He also attended Holy Ghost Prep in Bensalem Township.Philadelphia Mayor Jim Kenney issued the following statement Sunday afternoon: "I'm extremely saddened by the tragic death of Nicholas Flacco. Every life lost to violence is one too many. It is all the more tragic when we lose a young person who had their whole life ahead of them. I extend my deepest sympathies and condolences to Chief Inspector Flacco and his family, the Police Department, and all who have lost loved ones to senseless gun violence. PPD is undergoing a thorough investigation and I urge the public to come forward to report any tips that can help find the person who did this. The anonymous tip line is 215-686-TIPS."
