I couldn't figure out how to delete my last post ? but I believe that link gives info to this idea ! with pics
"On Friday, Police General Somyot claimed that investigators found Hannah Witheridge's mobile phone Thursday night (October 2nd) near the room where Wyn, one of the Burmese suspects, currently resides."
The picture on the right was taken on the night of the murders (September 15th). The picture on the left is from a video taken the day after Hannah's murder (September 16th) at the police station. Her friend can be seen speaking with police and the phone is clearly there also. H
