On October 9, Matthew Stone Sr., a 45-year-old man in Erie, Pennsylvania, killed eight people before taking his own life. The victims included his wife and five children, along with two other women who had come to assist them. Police described the scene as one of the worst they have ever encountered, noting that the house was extremely filthy and filled with bottles of urine.

The shooting occurred after 9 pm when residents called 911 due to hearing gunfire; upon arrival, officers found two women dead outside the home. Stone barricaded himself inside and engaged in a standoff with police before dying from a self-inflicted gunshot wound. Inside the house, investigators discovered additional victims, including children.

Police revealed that Stone had exercised strict control over his family for years, managing their finances and restricting their movements. The home's conditions were described as deplorable, further highlighting the isolation and distress experienced by the victims.
