Investigators have obtained evidence implicating a police officer in offences committed by alleged cyanide killer Sararat “Aem” Rangsiwuthaporn.
A source said investigators were expected to apply for a warrant for a police lieutenant colonel, said to be the prime suspect’s former husband, Pol Lt Col Withoon Rangsiwuthaporn.
The source said investigators had found that millions of baht had been transferred from her bank accounts to bank accounts held by the police officer.
Investigators on Tuesday questioned Pol Lt Col Withoon, deputy superintendent of the Suan Phueng police station in Ratchaburi, for the second time.
Earlier, the officer said that he and Ms Sararat divorced three years ago, but they still lived in the same house because they had to help each other take care of their two children.
During that time, Pol Lt Col Withoon gave money to his ex-wife to lend out. When she made profits, she transferred the money back to him but the amounts were not high, he reportedly said.
Investigators are thoroughly examining the money trail of the pair. They are also trying to determine if Pol Lt Col Withoon was aware when Ms Sararat committed the murders.
Police said on Tuesday that there were now 14 dead victims and one survivor.
Ms Sararat, 36, dubbed “Aem Cyanide", was arrested on April 25. Currently four months pregnant, she is being held without bail at the Central Women’s Correctional Institute.
