Police yesterday summoned wife and daughter of murdered night entertainment tycoon Somyot Suthangkool for the fourth time, as well as Somyot's three lawyers, to garner information about a supposed land dispute Somyot was involved in before being slain.
Somyot, 62, was shot dead outside a shark fin soup restaurant on Monday night.
His daughter, Natthida, 25, claimed her half brother, whom she had previously suspected to be behind the murder, as they both disliked each other, was unlikely to be the killer. Her mother, Rassamee, concurred.
Natthida confirmed that her parents had a conflict two years ago but as far as she knew her father hadn't physically hurt her mother.
"Once my dad was angry and was about to choke my mum but I stopped him," she said, adding that reports of her father losing a lot of money in gambling were untrue because he mostly won and was quite disciplined.
Rassamee told police that the fight two years ago was over a Bt60-million (S$2.39 m) juice factory investment, which she didn't tell Somyot of in advance, but he was never physically violent towards her. She said prior to his death, Somyot had helped her at the factory and they were happy together without any problems.
In relation to his murder, she pointed the finger at people who owed him money over gambling and those involved in a land dispute with him.
After meeting the case investigators yesterday at Klong Tan Police Station, Metropolitan Police Area 5 investigation superintendent Colonel Supat Peungpoung said police were continuing to mull over various possible motives but still gave more weight to Somyot's conflict with someone close to him as the likely reason for his death.
Police would soon summon the family member that Nattida mentioned, he said, adding that investigators would re-examine security camera footage before and after the shooting to try to determine for sure where the two attackers went.
Supat said the footage previously showed the duo disappeared near Ramkhamhaeng Soi 24.
