NORTH FAYETTE TWP. (KDKA)- The Allegheny County Homicide Squad is investigating a deadly shooting inside a North Fayette Township bar.
According to police, the shooting happened around 12:45 a.m. Monday at the Fort Pitt Inn in the 7700-block of Steubenville Pike.
A man in the bar became agitated with someone he was having a text message conversation with, abruptly got up and walked out to his truck. He has been identified as David Mazzocco, 25, of Imperial.
Mazzocco grabbed three guns from his truck, walked back into the bar and opened fire.
“He was having relationship problems and may have been in the midst of an argument with someone via his cell phone and text messaging. Left the bar, went out to his car, returned to the bar with what we know now is three hand guns. He gets into the bar and tells two of the patrons to leave. He then starts shooting the other patrons of the bar,” Allegheny County Police Lt. Andrew Schurman said.
Two men were shot in the head and one of them was pronounced dead at a local hospital. That victim has been identified as James Adams, 29, of Imperial.
The other victim was last listed in critical condition at the hospital. Their name has not been released at this time.
Two other people in the bar courageously tackled Mazzocco to the ground and subdued him until police could arrive.
“The two men who intervened need to be applauded for what they did. It was very courageous,” Schurman said.
