The hunt continued on Monday for a former police senior sergeant major wanted in connection with the murder of a restaurant-pub owner in Nakhon Ratchasima on January 10.
Police believe Polsak Boonreung has remained in the Northeast since the killing of Weerachai “Sia Kim” Loariyathanachote last week.
Bua Yai district police superintendent Pol Colonel Kharom Boonsod said on Monday 10 witnesses had been interviewed and an arrest warrant for Polsak had been obtained.
He said investigators were convinced that Polsak was linked to the murder and believe it stemmed from a personal conflict.
Kharom said locations around the Northeast where Polsak might be staying with friends were being searched.
Weerachai, 41, was shot seven times in the torso while driving his pickup truck home. His girlfriend, riding with him, was unharmed.
Weerachai managed to complete the 150-metre drive home and was then taken to hospital, where he died.
Possible motives include a conflict with three individuals whom Weerachai sued four years ago for trying to kill him.
Two of his attackers were jailed, but the third suspect in the attack – Polsak – was free on bail, having meanwhile lost his job.
Late last year he failed to appear for the reading of the verdict against him in Supreme Court. The court sentenced him in absentia to 18 months in prison.
