Jerry , how can you be so sure that he was not a serial killer or had committed other murders ? Look at the facts ...he had an empty suitcase on the ready , he chose a very small bodied victim that would fit , after stuffing her in the case he left her in the bathroom and carried on as normal all day. Did his laundry , went shopping ,had a couple of meals at his local restuarant , bought some beers at the 7/11 , and watched a movie as if nothing had happened.Then at 9.15 pm he put the case with the body on his motorbike and dumped her at his pre-selected site. If this was the first time this grub had ever done this kind of thing do you think that he would just have a normal relaxing day or would he be panicking and stressed out ? If I were the Police I would be checking all missing persons lists in the Pattaya area for other possible victims.
