Krittiya Lamsam, former executive of Muang Thai Insurance, was found shot dead in her room Friday evening, police said.
Police suspected that her Swiss husband shot her before turning the gun on himself. The man was found dead inside the toilet room next to the bed room where Krittiya was killed.
Krittiya was shot at her head while her husband apparently shot himself in the mouth. He was still holding to a 11mm pistol when the body was found.
The couple were living on the second floor of the family’s six-floor residence on Narathiwat Ratchanakharin Road in Yannawa district.
Relatives heard the two quarrelling before they heard the gunfire and found the bodies.
