Police spoke confidently this morning of wrapping up the case involving an alleged serial killer accused of poisoning 15 people.

Lt. Gen. Surachate Hakparn of the Royal Thai Police said he is preparing to conclude the investigation into Sararat “Am” Rangsiwuthaporn, known in the media as Am Cyanide, this Friday. He said there was enough evidence to support charging Sararat with six to seven serious counts in each of the 15 murders she is suspected of.

“We have found clear evidence,” said the cop known as Big Joke. “We have found the actual vials of cyanide that Am ordered, and we have found traces of cyanide with Am.”

Surachate said their attempts to determined who sold the cyanide to Sararat led them to conclude she purchased it online. 

“And we have identified which vials were purchased, a total of over 700 vials,” he added. “Therefore, in terms of the investigation, we have sufficient and clear evidence.

Sararat, who was pregnant at the time of her arrest, suffered a miscarriage last week.

He added that any government officials whose negligence helped Sararat obtain the cyanide she used to poison her victims would be held accountable. To date, money has been the motive for her alleged murders. In fact, Surachate said they linked Sararat to upward of THB80 million in transactions involving illegal gambling websites.

That indirectly connects the case to another police crackdown led by Surachate in recent months against large gambling operations headed by wealthy and powerful figures.

Thailand’s most notorious serial killers, by the numbers

Central Women Correctional Institution director Soraya Ritthiaram said Friday that Sararat’s miscarriage a few days earlier was caused by complications arising from high blood pressure and organ damage.

Regarding the possibility of Sararat or her attorney filing a legal complaint against the investigators for losing her child, Surachate said that it was their right to do so, but he was unconcerned.

Sararat was reportedly six months pregnant at the time of the miscarriage. Her legal team stated that it was planning to take action against Surachate for putting too much pressure on their client.
