A 36-year-old woman is believed to be the worst serial killer in Thailand's history, according to police. The suspect denies the murders but admits to using cyanide.
A Thai woman is facing 80 charges including premeditated murder, with authorities claiming she used cyanide to kill 14 people after previously swindling them.
Thai police said on Friday they have concluded their investigation into Sararat Rangsiwuthaporn, who was arrested in April after reports from the families of many of her alleged victims.
The suspect is believed to have stolen or borrowed money from nearly all of their victims, before mixing cyanide with their food between 2015 and 2023. One of her victims has survived.
Sararat denied murdering the victims but confessed to using cyanide, Thai police said. The deadly chemical rapidly interferes with the body's ability to use oxygen.
