I read this story and couldn't believe it. Seriously . . . robbing her I could understand. But raping?! She is 99! Wrinkly taint for the lose.
He is 17 for god's sake! What is wrong with him that he couldn't get good sex with someone that wasn't alive during the Great Depression.
Oh! Oh wait . . . he has the mental defect that causes him to want to rape a 99 year-old. That would probably turn any normal girl away with a quickness.
