I think Chadwell could well be BG.......
*looks younger than he is
*is a mixture of both sketches (including scar on lip / bridge of nose shape / markings)
*has a similar build / height /sloping shoulders
*has questionable tattoos (possibly depicting a murder victim) and quite a lot of them (that would require him wearing high neck / long sleeves if he was BG)
* his stance / gait is similar from pictures I've seen (one in the orange t-shirt with his hands in his pockets).
*is a bold predator that acts in the spur of the moment (an opportunist)
*is an outdoor enthusiast with a love of bridges (who would be able to confidently cross the MHB like a pro)
*lives fairly locally
*Has a similar voice / twang
*seems to have a problem with women (so in his most recent crime of opportunity he chooses a 9 year old)........... "It's all about power to you".
So hopefully LE are currently checking phone records (pings), checking his phone / electronics / USB's / storage devices for pics and audio, digging into his whereabouts / vehicles owned on 13th-14th Feb 2017 and ripping his house to shreds.
Don't be fooled by the soppy / pained ********, this bloke can flip / change like the wind into a violent paedophile psychopath (that poor little girl probably wouldn't have been leaving his house alive if it were not for the heroic policemen that sensed something off and went back to check).
We're all keeping everything crossed that justice will be served for Abby and Libby, soon we hope that "today is the day"
JMOO folks, even if he's not BG he's 1 more dangerous *** off the streets who cant hurt another little girl.
*And just for the record, I don't believe BG is any kind of criminal mastermind, I just think he got VERY, VERY LUCKY.
