One of the weirder stories I know of is the story of the murders of Butch DeFeo in Amityville, NY where he gunned down his entire family as they slept. It's unknown how all of them could have been shot without any of them being awakened by the gunfire, as the rifle used was not equipped with a silencer. Nor did the neighbors hear anything. Paranormal interference? Anyway, here are some pics, click for full size.
And here's something even stranger: a picture taken in the house some time after the murders, when there were no children there.
