This is truly bizarre. I mean, if he was going around breaking into homes of young women, or attractive ones, that would be bad enough, but why the fetish for elderly women? The only way I'd have attraction for elderly women is if I was an elderly man, and the attraction was for my wife or girlfriend, or other elderly women if I was widowed or divorced.
I've heard of tickle attackers before, like the guy in NYC years ago who would tackle women on the street, pull off their shoes, tickle their feet, and steal their shoes.
What a whacko this guy is!
