I just watched bits of episode 3 again to try and find the document with Vincent Bourg's details on that Trunchball spotted.
I don't know how to link to the screenshot of the relevant scene but Trunchball I'm sure that you'll be pleased to know that the episode 3 document has Pierre Bourg born in Lille and Vincent's mother, Mary Scotts, born in Dartford. It gives Vincent's profession as Ouvrier (worker).
It is at 44 minutes into episode 3 if anyone wants to have a look.
Other bits of information I picked up were:
Tony assaulted Greg in February 2000
Tony made payments to Greg in February 2000
Greg admitted to Tony that he had kissed Emily
Ollie's fracture occurred in September 2004 when he was almost 3 years old.
Ollie was 5 years old when he vanished in 2006.
Tony does not have an alibi for the 9 minutes between 10.16 and 10.25 on the evening Ollie vanished.
In 2006 Julien Baptiste has two pictures on his desk. One is of a little girl with straight red/blonde hair aged about 2. One seems to be of an older boy.
