The lecturer of Phra Nakhon Rajabhat University who shot dead his two colleagues on the campus on Wednesday committed suicide by shooting himself with the same pistol after more than five hours of standoff.
Dr Wanchai Danaitamonut was rushed to Paolo Memorial hospital by a waiting ambulance after he shot himself at a hotel in Sapan Kwai area where he had been hiding since the fatal shooting of his two colleagues on Wednesday. He was pronounced dead shortly after his arrival at the hospital.
Police, friends, relatives and students of the university tried desperately for more than five hours since 12.30 p.m. to talk Dr Wanchai into laying down his weapon and turning himself in to the police.
Dr Narongsak Boonyamarik, a close friend of the suspected killer, said that the police had tried their best to persuade Dr Wanchai to surrender but without success.
He said that during the lengthy negotiation Dr Wanchai was hesitant and was heard to have complaining “Unfair, can’t stand it.”
Dr Narongsak further said he received a text message sent from Dr Wanchai lamenting of the unfair treatment and threatening to kill himself.
