I agree - what do all of RG's alleged crime scenes have in common? .. it seems like he may have known of or was familiar with their routines -
I think that's it too, wasnt_me.. Rudy was running from someone, hiding..
we know, a couple of years earlier, he was in a fight over drugs and someone stabbed him.. (he probably carried a knife for protection).. maybe he started helping the police for protection (hence informant?)
although, in the article, it says he was running from police (Milan police).. do you have any idea why?
But there was another Rudy, the small-time drug dealer and drifter with a record of petty crime who according to some witnesses harassed women and stole from their handbags. Shortly before Kerchers murder he was detained in Milan for an alleged theft. He had broken into a school to hide from police and had a knife in his hand. source
we need a (Rudy) timeline - he broke in and stole the laptop/cell phone, left Perugia, went to Milan and was caught in the nursery.. then back to Perugia. I wonder if the trips coincide with the cottage lurker - from what I understand, G. saw someone lurking in the bushes.. separately, (2 weeks before she died) Meredith saw someone in the bushes - (I'll have to find the link)
