In Feb 2004, shortly after moving to Thailand, Cohen, then aged 36, bought a one-way ticket for his ex-wife to fly to Bangkok. The pair were divorced, but he said he missed her and wanted to see her.
Within 24 hours of her arrival, he murdered her in his hotel room, dismembered her and stuffed her body into a suitcase, which he threw in the river.
Cohen initially denied murdering his ex-wife. But police immediately suspected he had killed her, after finding parts of her body scattered around Bangkok’s canals. He eventually pleaded guilty, but denied the murder was premeditated.
