See Uey Sae Ung (or Si Quey), or more commonly known as Thailand’s Boogeyman, was a Chinese immigrant who came over to Thailand in 1944.

See Uey Sae Ung was a former soldier who fought against the Japanese invaders on the Chinese island during World War 2. It was rumored that his bloodlust was influenced during the war because “his military commanders told the troops to eat the livers of the enemy soldiers to take on their strength and power”. Upon his immigration to Thailand, See Uey Sae Ung toiled as a coolie, rickshaw-puller and a vegetable farmer. He also made his way to become Thailand’s most legendary serial killer.

He was known to have suffocated more than half a dozen of young boys and ate their hearts as he thought that by eating the heart, he would gain special powers. He was executed in the 1958 and his body was mummified and is currently on display at Bangkok’s Siriraj Medical Museum. There is not much information about him on the internet though, the only information about him is in a newspaper clipping in Thai, taped to the side of his final resting glass case in the medical museum.

(On a side note, PLEASE VISIT SIRIRAJ MEDICAL MUSEUM BECAUSE I HAD THE TIME OF MY LIFE THERE – If you are into pathology/forensics shit, PLEASE GO. Only approx. SGD8 for the entry.)

Well, to know that you have succeeded as a serial killer is when you managed to become a legend. The people of Thailand used Si Quey to scare young children in saying that if they return home late, Si Quey will eat their heart.
