CHARTIERS TOWNSHIP, Pa. – Washington County District Attorney Jason Walsh says multiple charges have been filed against a Greene County woman in a shooting late Wednesday night in Chartiers Township. Walsh says 27-year-old Michaela Marie Hildreth of Nineveh faces charges of attempted homicide, aggravated assault and simple assault, for shooting 39-year-old Amy Mruk following an altercation in the area of 290 Moon Road. Authorities say Mruk was shot in the chest and was taken to Washington Hospital for treatment. Police say when they responded to the call they found a Black Chevrolet Tahoe in the middle of Moon Road, where the confrontation allegedly took place. In the car was John Thomas Mruk Jr. who told police that the victim was his ex-wife and she had been shot by Hildreth, his girlfriend. Police say they recovered the weapon they believe was used in the shooting, a Glock Model 43x 9mm gun.
