I thought maybe he had been to the gym and had been heading home and seen her, the route would be correct and would explain his attire however I've just checked and the gym closes at 10pm on a Thursday so that can be ruled out.
Anyone know what times/days when he was reported to have been flashing? Could this match up?
Unless he waits for his wife to be asleep everytime he goes out at night then he must tell his wife something surely, like: I'm just off for a run or I'm off to get a takeaway, so what happens in this area at that time that may give him his alibi?
If he had told his sister about the girl on Beverley road then surely he said something to his wife also, so wherever he was supposed to be going this must have been the route or she would question why he was there.
For him to have told his sister to me seems like a panic reaction, he's worried and needs to come up with an excuse, he reels off this story to his sister, it kind of creates an alibi for him, someone to back up his claims.
I'd read that he was worried because he was acting as a taxi service and that why he didnt come forward, was this just speculation or did this come from the sister also?
I'm still thinking he took her somewhere and didn't kill her, being a Pervy creep and being a murderer is a big step up.
