Expressway killer reveals 3 month plan to murder girlfriend in remorseless confession

In a remorseless confession, the Thai man who killed his lover and buried her body parts in plastic bags underneath an expressway in Bangkok told police how he meticulously planned his girlfriend’s murder for three months.

In his confession, the murderer said he and 30 year old Pin were together for two years and he was very much in love with her. However, 35 year old Chanwit started to realise that Pin was distancing herself from him.

Not wanting Pin to go off with anyone else, jealous Chanwit began planning her murder three months ago. He said he got the idea to chop her up and bury her from a film.

Chanwit studied the film and learned that he would need a sharp axe to dismember Pin’s body by chopping it up at the joints.
