A 40-year-old man surnamed Wei in Sandu Shui Autonomous County, Guizhou province sought revenge out of emotional frustration. He broke into his ex-girlfriend’s house with mercury and rat poison and poisoned a large-scale water dispenser, spicy chili bags and pillows. Fortunately, the victim’s family discovered the water stain in time and called the police by accessing the surveillance camera and the man later surrendered. The local people’s court recently concluded the case was caused by emotional conflict and sentenced Wei Nan to four years in prison for intentional murder (attempt).
Farmers Daily reported that prosecutors and courts investigated and found that Wei Nan, 40, was dating a woman named A. A left Wei Nan in early January 2026 and started a family with a woman, B.
Wei Nan believed that the woman was in two different states during the relationship, so she held a grudge and had thoughts of revenge. On the evening of February 11, 2026, Wei Nan went to the house of a certain B, carrying 8 bottles of “three-step” rat poison, gloves, hoods, and about 30 mercury thermometers. On the way, he broke the thermometer to collect the mercury and filled it in a bottle, and then quietly entered the house while no one was home.
After Wei Nan broke in, she poured rat poison into the water dispenser, tea bucket, tea kettle, kettle and mineral water bottle in the bedroom on the second floor. He also put mercury under the pillow in the master bedroom, and put the poison in two plastic wine buckets and unsealed pepper bags on the first floor. He wiped the water stains on the ground to confirm that the poison could not be easily detected, then discarded the container.
That night, around 8 p.m., his family discovered that the monitor was being used strangely and called the police. On the morning of February 13, Wei Nan was persuaded by his family to surrender and compensate the victim for the loss of 20,000 yuan. The court considered this to be surrender, admission of guilt, and compensation for punishment and damages, and sentenced him to a lighter sentence in accordance with the law and 4 years in prison.
