This is something that makes my spine crawl just hearing others talk about it. Many years ago, an aunt from my mom's workplace. She had just retired a week ago, and she died.

And her husband died with her. The couple was stabbed dozens of times, blood flowing like a river. The aunt's breasts and reproductive organs were also cut off, the scene was too horrific to bear. When neighbors found them, they had already passed away from blood loss!
The murderer was caught the next day, it was the daughter’s boyfriend.
Because the boy's family was not well-off, the old couple had always disapproved of their relationship and never gave the boy a good look. The boy seemed honest and kind, and they lived very close, knowing each other well. Aunt and her husband were both very strong-willed, believing the boy's family was not worthy of them. Amidst arguments and quarrels, the daughter and the boy still couldn't part ways.
Then, the girl got pregnant, and the old couple was furious. The boy knelt down, begged to marry her. In front of the daughter, the aunt kicked the boy away and told him to get lost. That night, he took a train to his relatives in Beijing with the girl, then had the fetus aborted.
At that time, the boy didn't know the child was gone, he thought the girl was just taken out for a walk by her parents. He could only wait downstairs every day for his lover to come back. After a few days, the old couple returned, and the girl was left at the relatives' house. In front of the neighbors, the boy again kowtowed to apologize, swore he would treat the girl well for the rest of his life!
The aunt loudly declared that he should forget about it, that he would never set foot in their house again. The boy then clung to the aunt and her husband's legs, begging them to see the child and agree to him marrying the girl. The neighbors couldn't stand it either and helped speak good words for the boy. The old couple sneered: "That bastard child has already been aborted!" They turned around and went home, slamming the door shut.
Under everyone's persuasion, the boy slowly got up, brushed the dirt off his knees, and walked away without looking back.
Because it was summer at the time, everyone was sleeping with the windows open at night. The aunt's house was on the fifth floor, and in the middle of the night, the boy climbed up through the drainpipe. He directly stabbed the old couple to death with a knife, and in the end, perhaps still felt unsatisfied, he also cut off their body organs.
Later, the boy was sentenced to death and executed by firing squad. He was an only child, the only kid in his family. The girl also lost her parents, haunted by the shadow of three lives lost.
