I see there are two new local posters - welcome both.
From what you've posted you are more local to Ibstock than me, I'm more familiar with the other places involved. Maybe this area is different to where other UK posters live but ime eveyone tends to know everyone and is they didn't go to school with them they know someone who worked with their mother etc - you get my drift.
From these kind of connections I've been told other the last couple of days (and I can't prove this so MOO etc) that SB lived fairly recently in Belton which would explain why he might have returned there to hide things or get rid of evidence and I've also heard that all 3 were seen together over the weekend (I don't know which day) somewhere that hasn't been mentioned so far and that Kayeigh didn't appear to be with them under duress.
If this isn't allowed please delete Admin.
Also just to clarify and I think someone else has mentioned this above it's common for schools to be called colleges here and the Ibstock college only goes to age 14, being dropped off outside one to meet a friend isn't the slightest bit odd imo, it's just a convienient spot for a parent to drop off a child I really wouldn't read anything into that location at all.
