Death penalty for alleged cyanide serial killer in Thailand

A Thai woman believed to be among the worst serial killers in the kingdom’s history was found guilty of poisoning a friend with cyanide and sentenced to death on Wednesday in the first of 14 murder trials.

Online gambling addict Sararat Rangsiwuthaporn, 36, is accused of defrauding his victims of thousands of dollars before killing them with a chemical agent.

A court in Bangkok found him guilty on Wednesday of fatally poisoning his friend Siriporn Kanwong.

The two met near Bangkok in April last year to release fish into the Mae Klong River as part of a Buddhist ritual.

Siriporn collapsed and died a short time later, and investigators found traces of cyanide in his body.

Police were later able to link Sararat to unsolved cyanide poisonings dating back to 2015, officers said.
