House comes back to a William Spengler.
William Spengler was just confirmed by Webster PD Chief to be the killer and he died of a self-inflicted gunshot wound. He murdered his grandmother, who lived next door, back in the early 90's. He was a criminally deranged POS and convicted felons are not allowed to own guns in NYS, so he committed this ambush and murders and assaults with illegally obtained guns.
I've spent time down at Sea Breeze, at the amusement park and the burger/hot dog joints as well as at Marge's Lakeside Inn and the Reunion on Culver Rd.
