The cruel crime of a woman who used cyanide to poison 4 relatives
A woman in Dong Nai has been proposed for prosecution for using cyanide to poison four relatives, including her husband and grandchildren, causing a stir in public opinion.
The Investigation Police Agency of Dong Nai Province has just completed the investigation conclusion and transferred the case file to the Provincial People's Procuracy to propose prosecuting Nguyen Thi Hong Bich (39 years old, residing in Phuoc An commune) for the acts of "Murder" and "Illegal production, storage, transportation, use, and trading of flammable and toxic substances".
It is worth mentioning that the victims in the case were none other than the defendant's husband and family members.
Created a scenario of using "liver detox" medicine to poison his nephew
According to the investigation, Bich lived with her husband, Mr. Nguyen Thoai Thanh T. (40 years old) and 2 children in Group 4, Son Ha Hamlet, Vinh Thanh Commune (now Phuoc An Commune) in her biological father's house and with her brother's family. Bich's family sold rice at home to serve local people and workers in the area.
In June 2024, Bich had a conflict with her sister-in-law over money. From there, the woman had the idea of poisoning NHBT (19 years old, her sister-in-law's child) to "take revenge".
Taking advantage of T.'s acne, Bich approached her and said that she had had the same problem before and had recovered thanks to liver-cooling medicine. When T. agreed, Bich went to the pharmacy to buy the medicine but asked for it in capsule form. After that, this woman poured out the medicine inside the 2 capsules, replaced it with cyanide and gave it to T. to drink.
Immediately after that, Bich took her daughter on a motorbike and left the house, creating an alibi. Meanwhile, T. had just finished drinking and collapsed in the living room. The victim was discovered by relatives and taken to the emergency room in time, saving her life.
Test results from the Ho Chi Minh City Institute of Public Health showed that T.'s gastric juice contained 21 mg/L of cyanide, an extremely toxic substance.
Revealing the act of poisoning her husband and two young children
The incident was reported to the police by relatives. During the investigation, Bich confessed to having used cyanide to poison three other relatives, including her husband.
In 2022, due to her husband's debt, Bich went online to buy cyanide for 1 million VND to commit suicide. However, seeing that her husband was in debt, she decided to kill him with cyanide.
Specifically, Bich confessed to having switched her husband's medication with a capsule containing cyanide. Her two nieces, NKD (8 years old, her sister's child) and NHN (13 years old, her brother's child), were also given cyanide by Bich, leading to their deaths.
The investigation agency seized a plastic bottle hidden at the cemetery, containing white crystals weighing 784 grams. The results of the examination determined that it was potassium cyanide.
Regarding the unusual deaths of Bich’s biological father, Mr. Nguyen Van H. (69 years old) and his biological daughter NHM (15 years old), the investigation agency does not have enough documents to determine that they were poisoned with cyanide. However, these two cases are also being considered for further investigation.
The investigation agency determined that Bich committed cruel, sophisticated and continuous crimes against family members until he was discovered. Realizing that Bich's human nature was no longer capable of being educated and reformed.
“Therefore, the investigation agency found it necessary to permanently remove defendant Bich from society for the purpose of deterrence, education and general prevention of crimes related to the use of toxic substances,” the investigation conclusion stated.
