I've been to this park, is us a part of a school playground and is backed by a 8 ft concrete wall, on the other side of the wall are homes... Someone could very easily reach over and shoot and slip back behind the wall, especially if one of those homes is vacant.

Is this a gun free park? Good logic commentators, but the bullets were fired from outside the park and then the shell casings were dropped in the park by a drone flying overhead. Are these self inflicted?

@Dominiator, LOL!

"The weapon was a .22-caliber handgun or rifle and several shell casings were found on the ground, Metro public information Officer Marcus Martin said. It was unclear if the shooter fired from inside the park or outside the park, Martin said." Duh!, Let me see... Where the shell casings found inside the park or outside the park? Duh!
