Khao Wong district police had to break open the front door of the two-storey home of Amornrat Busamongkol, 56, in Ban Saen Suk, Tambon Khum Kao.
They found his body on a sofa with a .22-calibre rifle nearby and the body of his wife, Homchan Busamongkol, also 56, on the floor of the living room with a gunshot wound to the head.
It’s believed Amornrat committed suicide by placing a toe on the trigger of the rifle with the barrel in his mouth.
He was a former member of Khao Wong Municipal Council.
A relative, Suthin Nathewet, told police he got no answer when he phoned Amornrat and went to investigate, finding the house doors locked.
He looked in a window and could see Homchan’s body lying in a pool of blood.
