Hang Dong police were called to the scene of a shooting in a bedroom behind a mini mart in their jurisdiction.
Sawat, 48, a civil defense volunteer in Chiang Mai had been shot in the chest.
He was rushed to hospital but was pronounced dead.
Waiting for the police, that included provincial deputy chief Pol Col Piyaphan Patrapongsin, was the man’s wife Wilaiwan.
She had the murder weapon – a Glock 9mm – still in her hand and was crying profusely.
Sanook said she was aged 60 and admitted to shooting her husband.
She said that they had been together for ten years and that Sawat was a serial philanderer with many “giks”.
She had told him to stop dallying with his mistresses many times but he still persisted.
On this occasion she grabbed his gun and shot him in the chest.
She has been charged with murder and detained. – Sanook
