A man fatally shot his pregnant girlfriend and severely injured her father and himself inside the Nakhon Pathom Hospital on Friday at around 1:30pm.
Police did not identify the attacker and two victims.
Witnesses told police that the young man turned up at the hospital and had a dispute with the woman and the older man who appeared to be her father. The young man was heard shouting about why he had been kept in the dark about the pregnancy and pulled out a .357 revolver and fired at the woman and the man before turning the pistol on himself.
The woman later died while the two men were in critical condition.
Other patients were shocked by the sound of gunfire.
