WEBSTER, N.Y. (AP) — The ex-con who lured two firefighters to their deaths in a blaze of gunfire left a rambling typewritten note saying he wanted to burn down the neighborhood and “do what I like doing best, killing people,” police said Tuesday as they recovered burned human remains believed to be the gunman’s missing sister.

Police Chief Gerald Pickering said 62-year-old William Spengler, who served 17 years in prison for the 1980 hammer slaying of his grandmother, armed himself with a revolver, a shotgun and a military-style rifle before he set his house afire to lure first responders into a death trap before dawn on Christmas Eve.
