UPDATE Human remains found in Spengler's car believed to be his sister.
Earlier: News conference at 11 a.m. in Webster, N.Y. just concluded reveals that shooter William Spengler left note detailing his plans--and used three weapons, including same type of .223 Bushmaster used by Adam Lanza in Sandy Hook. From his note: "I still have to get ready to see how much of the neighborhood I can burn down and do what I like doing best: killing people.” Two or three-page note but revealed no motive.
More on weapons: a Mossberg 12 gauge shotgun and a .38 caliber Smith & Wesson revolver and a stockpile of ammunition.
Spengler's sister, who lived in same house (and he hated her) still missing.
Two firefighters shot and survived in "stable" condition.
