Horrific is really the only way to describe it. I literally came to tears trying to relay the story to my wife.
Here is the article in The Tennessean that is the most thorough. Be warned that the article is tough to get through. (EDIT: That article has been cut down to a stub as of 9/4/2012 1132am.)
A 14 year old Boy Scout, his 48 year old mother, and his 71 year old grandmother were stabbed to death by a neighbor at around 2:30 in the morning. A 9 year old girl escaped to her neighbors house, screaming “he’s kiling her” over and over again. That neighbor grabbed a gun and ran to the house, but couldn’t get in.
The suspect knew the victims well. Early indications are that he was a 9/11 paramedic who was suffering from PTSD and may have been suicidal the day this happened. He apparently tried to stab himself after the murders, and met police at the door saying “Please kill me.” He’s in ICU at Vanderbilt Hospital.
The scene is so gruesome that responding officers are in counseling.
Now if you’ll excuse me, I have to go hug my son.
