Ambridge Police Chief James Mann said police received numerous 911 calls overnight Saturday regarding gunfire from the area of 819 Maplewood.
Police found six shell casings fired from a .380 semi-automatic pistol in close proximity to each other off the front of the porch. No shell casings were found in the street or yard, leading police to believe the weapon was fired from the porch. No one has been charged.
"It's still under investigation," Mann said.
