In 1918, a heavy iron chest washed ashore near Bangkok. Inside was the body of a young woman named Prik — and the beginning of one of Thailand’s darkest stories. Her killer, Boonpeng, was a monk who used black-magic rituals and love potions to seduce and destroy. Known today as Thailand’s first serial killer, he confessed to sealing his victims in iron chests and sending them into the river. His execution — Thailand’s last public beheading — marked the end of one era and the birth of a haunting legend.
