A Pennsylvania man threatened to demolish his family home and then carried out the threat with an excavator while his wife and daughters were still inside, turning a marital dispute into a scene of destruction.Eric Pierwsza, 48, vandalized his backyard in Butler County after an argument with his wife after a night out drinking. The damage was so severe that investigators believe the entire house is no longer safe or structurally sound.According to CBS Pittsburgh, the confrontation began when Piervezza’s wife told him their marriage was over. In response, he warned her: “If this is over, I will tear the house down.”Police say he then got into an excavator and began tearing up parts of the property. His wife and his two daughters were inside the house when the machine fell into the building. During the 911 call, the sound of an excavator hitting the walls could be heard in the background. After the destruction stopped, Pierwsza went back into the house, picked up a gym bag and left the area. Later the police traced him and took him into custody.He has since been charged with mayhem, reckless endangerment and disorderly conduct, among other crimes.Pierwsza’s wife planned to seek a protection from abuse order after the incident. The case has stunned neighbours, with many struggling to understand how an argument escalated to the partial demolition of a family home.“I would like to know what he said to her because I’ll make sure I don’t say that,” a neighbor told CBS News.He further said, “I have been married for forty-two years, but I have never threatened to break the house.”Pierwsza is scheduled to appear in court for a preliminary hearing on June 9.
