Hm, I think I got this one...
Tripp: So the babysitter said she saw someone at this window, right?. A possible peeping Tom.
Ryan: Maybe Tom was doing more than peeping.
Tripp: How can you tell?
Ryan: There's fresh tool marks from trying to get the window open.
Tripp: Maybe whoever it was left behind something more than tool marks.
Ryan: Yeah, it's a glass window, good surface for prints... maybe we'll get lucky.
It's from "Broken Home", I think.
PS: If I get this right, you may continue with the game, anyone else can post the new one, as I am off for school now and I don't want to keep you all waiting
