Police say a Pennsylvania gunman who killed several family members had strictly controlled their finances and interactions with others. Erie Police Chief Rick Lorah says investigators still don’t know why family patriarch Matthew Stone Sr. gunned down his wife, their three children, two grandchildren and two women who rushed to the home last week. During a news conference Thursday, Lorah painted a picture of a family living in a home in isolated, filthy conditions. He says Stone's authoritative behavior started after his wife became pregnant with their first child two decades ago. That included restricting when family members could leave the residence or spend time with relatives.
