Butler police today got an arrest warrant for a Pittsburgh man accused of firing a barrage of gunshots last week at a house in the 300 block of Wagner Avenue.

Joshua McKenzie, 30, a felon, is charged with two counts of aggravated assault, illegal possession of a firearm and discharging a firearm into an occupied structure, all felonies.

He also faces two counts of reckless endangerment and terroristic threats, both misdemeanors.

Police allege McKenzie about 7:40 p.m. Wednesday fired eight rounds from a 9 mm pistol into the house occupied by Rainy Rose and Ryan Mullen, neither who lives there.

None of the shots hit anyone, but Rose, 30, was struck by flying glass. She was treated at Butler Memorial Hospital for a cut to the back of her head and released, police said.

Investigators suspect McKenzie went to the house at 313 Wagner Ave. looking for Mullen, 29, who he believed had tried to rob his girlfriend at gunpoint in 2013, according to court documents.

McKenzie before opening fire pounded on the door and threatened to kill Mullen, police said.
