First comment, lurking since case began!
Just read through GBC's first interview and got chills as he was talking about how he cut his hand changing a lightbulb at a property he was renovating. I knew GBC & ABC through friends (they were good friends with our good friends) but only met them a couple of times. I also met Toni as she was going to sell our house in 2010 but we pulled out. I hadn't seen GBC for a couple of years until I was interested in the house he was talking about in this interview. I booked to have a look around and went with my friend (hubby at work) probably a month before Allison went missing. I found him very odd at the time. He flirted with me, whilst asking about my husband and two kids and I said to him "wow, how do you remember their names? Do you keep a database or something, haha??" And he said it's his job to remember. He was quite flirty (which i did not like) and said the owners of the property were his friends, he went camping with them, even camped on the property. He said they had renovated extensively, but he never mentioned that he had helped in anyway. He said they'd had their kitchen done etc etc but no mention of "oh I helped them with...blah blah...last weekend" or anything.
When I got home, I said to my hubby how strange he was and I said he'd lost a lot of weight (and sorry to the males reading this) and I thought normally men only lost considerable weight midlife if they were having an affair! I know that's mean but he just gave off a leery vibe and gave me the heebeegeebees, even though I sort of knew him.
Apologies for the long comment with little info but I've always found it interesting to hear from people who "know" him so thought it might be of interest. Will go back to lurking now and thank of of the real websleuths on here!
