From today's Daily Mail:
Lady's orange wig, lipstick and 'five regrets of the dying' newspaper cutting
found alongside body of spy in the bag, and SOMEONE ELSE locked him inside
Lengthy article, many pictures, and two videos at DM link above.
wfgodot,
Of course someone else locked him in. Why should anyone speculate otherwise?
Was he killed for gain, was his flat ransacked, was there a forensic trail left in his house?
Consider the death in China of british businessman and old Harrovian, Neil Heywood? He died allegedly from alcohol poisoning, then his body was cremated. Latterly the story breaks he was killed by the wife of a high ranking Chinese politician, Bo Xilai.
The common factor in both these cases is an absence of forensic evidence and the likely involvement of secret services.
So it appears Gareth Williams was relocated to his flat, in the bag so to avoid detection. A handheld, battery operated vacum-cleaner could have been used to remove any forensic residue. he was probably dead prior to being placed into the bag, otherwise we would have tear marks etc.
So it looks like Gareth Williams was killed away from his flat and for what he knew not for what he possessed. This points to a secret service and an ongoing intelligence operation.
IMO all the bondage detail is peripheral and tabloid fodder.
