A SUSPECTED serial killer has been sentenced to death for poisoning her pal on holiday as she continues to face a string of murder charges.
Sararat Rangsiwuthaporn, 36, has been dubbed “Ms Cyanide” after she was accused of giving 14 of her friends the lethal chemical because she allegedly owed them money.

A court in Bangkok today found the Thai mother guilty of putting poison in Siriporn Khanwong’s food and drink.
She is said to have smiled as the verdict was read out.
Sararat and Khanwong travelled to Ratchaburi province, together back in April 2023 to release fish into a pier and share some lunch.
But moments after eating Siriporn collapsed and died on the riverbank as Sararat watched on as she struggled, investigators said.
An autopsy carried out by Thai police later revealed the victim had ingested cyanide.
A complaint was filed by the 32-year-old victim’s mum and sister as cops started to investigate Sararat.
The shocking death prompted other families to come forward with horror stories of their loved ones dying after meeting up with Sararat.
Police quickly gathered up evidence and arrested the woman back in May 2023.
She was charged with fourteen counts of murder spanning back to 2015 with officials alleging cyanide was used in each death.
Cops say the people killed include pals, an ex-partner and a police officer known to Sararat.

A dozen were women while two were men.
Throughout the trial Sararat has continued to plead not guilty to all of the charges against her.
But she has confessed to using cyanide, according to Reuters citing police.
One person survived the alleged poisoning, court documents have revealed.
Siriporn’s heartbroken mum Thongpin Kiatchanasiri spoke in court as her daughter’s killer was jailed.
She held up a picture of Siriporn and said: “You got justice, my child. Today, there is justice in this world.”
Sararat has also been ordered to pay Siriporn’s family two million baht (£45,446) in compensation.
Police believe the killings were financially motivated after Sararat began racking up huge credit card debts due to gambling.
Deputy national police chief, Surachate Hakparn, said: “She asked people she knows for money because she has a lot of credit card debt.
“If they asked her for their money back, she started killing them.
“She had poisoned all 15 victims with cyanide that was placed in drinking water, food or medicines in the form of capsules.
“Financial problems were the motive for carrying out the cyanide murders.”
Three others involved in the case have also been charged with various crimes.
These include Sararat’s ex-husband, a former police officer and her lawyer.
They were handed prison terms of one year and four months, and two years respectively for hiding evidence to help the woman evade prosecution.
They had all pleaded not guilty before the sentencing.
Ex-husband, Vitoon Rangsiwuthaporn, gave himself up last year with police believing he is likely to have helped Sararat poison Suthisak Poonkwan – an ex-boyfriend.
