Key Takeaways
- A 21-year-old woman fatally stabbed her 23-year-old sister over 50 times inside their Bangkok condo.
- The suspect was reportedly angry that her sister revealed she had stopped taking her psychiatric medication.
- Police have charged the younger sister with premeditated murder after discovering a hidden kitchen knife.
The grim discovery was made by the girls’ 69-year-old father, Mr. Cheng, late that morning. Earlier in the day, he and his wife left their apartment to visit a local market. While they were out, the younger daughter called her mother to quickly arrange a ride.
She specifically told her mother to wait downstairs instead of coming up to the room. When the mother arrived, the suspect calmly claimed her older sister was simply sleeping. Worried by several unanswered phone calls, the father rushed back and found the tragic scene.
Investigators quickly began looking into the specific motive behind this incredibly violent family tragedy. During police questioning, the younger sister calmly confessed to carrying out the fatal attack. She told officers she was furious at her older sister for secretly checking her phone.
Mental Health Struggles and Medication Issues
Furthermore, the victim had discovered a closely guarded personal secret and told their parents. The younger sister had secretly thrown her essential psychiatric medication straight into the toilet. Feeling deeply betrayed, the suspect decided to take violent revenge against her own sibling.
The family had been managing the suspect’s ongoing mental health issues for quite some time. She was previously studying as a second-year university student in the northern city of Chiang Mai. However, she took a break from her studies to receive intensive psychiatric treatment in Nonthaburi.
Just days before the murder, the family visited the doctor because her symptoms worsened significantly. After her parents pressured her, she finally admitted to flushing her prescribed pills away. The doctor prescribed new daily medication, but the tragic incident occurred before it could help.
Police officers found clear evidence showing that the brutal attack was carefully planned. The suspect admitted to buying a 30-centimeter kitchen knife from a nearby neighborhood supermarket. She then waited patiently for the perfect moment when their parents left the apartment.
Premeditated Murder Charge
After committing the murder, she carefully hid the bloody weapon on a living room bookshelf. When her mother eventually brought her back to the condo, police officers were already waiting. Authorities quickly took her into custody and began searching the apartment for the hidden weapon.
Officers from the local Yannawa Police Station are currently handling the ongoing criminal investigation. The suspect now faces very serious legal charges for carrying out a deliberate, premeditated murder. Meanwhile, the victim’s body was sent to the Police General Hospital for a detailed medical autopsy.
This heartbreaking case highlights the severe challenges families face when managing unpredictable mental health crises. As the legal process moves forward, the local community mourns the loss of a bright graduate.
Authorities urge families dealing with similar psychological struggles to seek continuous professional medical support.
