PITTSBURGH — Pittsburgh’s SWAT team arrested a man who allegedly fired a shot from his home that pierced the bedroom wall of his 80-year-old neighbor.

That woman wasn’t injured, but police said 30-year-old Justin McQuade still faces charges of reckless endangerment and discharging a firearm into an occupied structure.

Police didn’t immediately explain how or why McQuade fired the shot just after 2:30 a.m. today.

The SWAT team entered McQuade’s home after 4:15 a.m. where it found several guns and several bullet holes in the walls.
