I don't know if gbc is guilty. IMO the strangest behaviour was from the very beginning when abc went "missing".
Why wouldn't he call the local hospitals first? Or check with police that there had been no accidents or pedestrians hit by vehicle etc?
Why go straight to reporting a missing person?
Also, the house being declared a crime scene is obviously a bell ringer. I wonder if he's attempted to " clean up" using harsh chemicals ex bleach which would smell very strongly and be very noticeable.
As to the interview with his sister and someone's claim he was on cocaine because of his pupils? He may well have been sedated by the doctor- his wife Has been declared deceased,or prescribed pain meds after his injury.
As for his demeanour, I don't know him personally, I am not familiar with his mannerisms or syntax but to apologise in the first breath... It's all very strange.
I hope closure is found for the Dickies.
I hope those poor girls can heal somewhere, in time and with love from their family.
I hope is Gbc is innocent then the damage done to his reputation can be undone.
It strikes me he may be covering up for someone.
All this is my opinion only.
Justice for Allison.
