A shocking love-related homicide case involving an international student has occurred in a Bangkok suburb, Thailand. A Chinese male graduate student attending a local university allegedly got into a violent altercation with his Thai university student girlfriend, then stabbed her more than 30 times in their apartment, killing her. He allegedly used what appeared to be blood to write a suicide note on the wall, and finally jumped to his death out of guilt, resulting in a tragic double fatality. Police preliminarily believe the incident is related to a relationship dispute and are investigating in the direction of murder and suicide.
The incident took place in a 9-story apartment building near a university in Pathum Thani Province. Around 1:30 a.m. on the 5th, local police received a report that a man had fallen from a height. When officers arrived at the scene, they found the body of a young man on the ground, with obvious cuts on his face and wrists, and confirmed he died at the scene.
● Covered in blood, knocks on neighbor's door; room filled with signs of struggle
Several hours later, police tracked down the deceased’s unit based on a tip from a 9th-floor resident. That resident reported that, in the early hours, a man with a bloodied face had knocked on his door. Frightened, he did not answer and instead notified security. When police broke into the apartment, they found clear signs of a struggle inside, with blood stains everywhere, and discovered another body, that of a woman, in the bathroom. The female victim was identified as 21-year-old Thai university student Nathanitsha, and the earlier deceased man who fell was her 30-year-old Chinese graduate student boyfriend, surnamed Dan.
The female victim sustained more than 30 stab wounds, with fatal injuries to her neck and chest. What shocked investigators most was the apparent suicide note written in English on the wall in what appeared to be blood, roughly stating: "I must go... I really tried my best. Understanding is more important than money...."
Police initially speculate that the two may have had a violent dispute, during which the man killed his girlfriend with a knife, then attempted self-harm, left a 'blood-written' note on the wall, and ultimately chose to jump to his death. Both bodies have been sent to a forensic institute for autopsy to further clarify the circumstances and motives surrounding the incident.
Preliminary investigations reveal that the deceased were classmates and in a romantic relationship. Since June 2025, Mr. Dan had been renting the unit. Forensic experts have been called in to analyze the handwriting and further assess the emotional state of those involved during the incident. Investigators believe the female victim's family is financially well-off, and there are no indications that the case was motivated by financial reasons.
