He drove to Tesco Lotus on a Honda motorcycle on Wednesday.
At the store he saw the victim who was wearing a heavy gold chain of two baht weight (worth 40,000 baht) and followed her to the handicapped toilets where he went in after her, turned off the lights and locked the door.
He threatened her with a knife he had with him but she fought back and he stabbed her twice in the side. In the commotion, a cleaner had heard and was banging on the door and calling for help.
Ranakorn then took off the victims lower pants and flinging the door open used them to hide his face as he ran for the exits. He dropped the pants by the main door and ran off pursued by a member of the public.
He drove 500 metres to a PTT gas station where he abandoned the bike. Then he went back to the store on foot and got on his own Honda that was there and drove the two kilometres to his relatives’ house where he was staying.
He said he needed the money to pay off an online debt after gambling on baccarat. He also wanted to gamble some more.
Lt Gen Sorasak said that the way that the criminal followed the victim and how he fled marked him as an experienced career hoodlum who was out of the ordinary.
The previous offences of the suspect were many.
After interviewing Ranakorn, Sorasak went with his entourage to Tesco Lotus. There he told the store that they need to beef up security.
He revealed that there have been three other cases resulting in three murders at that store alone.
It was then reported that Ranakorn comes from a very rich family. He is the blood grandson of a mayor in the Chumpon area.
He is also the grandson of a nationally known businessman involved in the delivery business both within Thailand and abroad.
His relative is said to be on the board of state and private companies in the Chumpon area.
