Three naked bodies were found in the荒wilderness, with bite marks all over their bodies and signs of rape.

It was the morning of the tenth day of the first lunar month. In a place called Shaohexi River in the suburbs of Yuhang, Zhejiang, a floating female corpse was found. When salvaged, it was discovered that the body was tied to a bicycle. After investigation, it was determined to be a case of robbery, rape, and murder, with extremely cruel methods. The victim was identified as a young woman who had gone missing twenty days prior. The police confirmed that the place where the body floated was not the original crime scene. So, where exactly was the first crime scene? The police labeled this case as the "225 Case." As they were intensifying their investigation, another violent case of rape and robbery occurred, with the same modus operandi as the 2.25 case, and the perpetrator also dumped the body into the canal! While sorting through the cases, the police noticed an unsolved case from three months before the 2.25 case, known as the "1130 Case." A young woman was abducted at night, rendered unconscious by the suspect strangling her neck, and then raped. After that case, despite a month-long stakeout, the police still couldn't locate the suspect's whereabouts! However, the police did find suspicious shoe prints and a small amount of hair left by the perpetrator at the scene, and they also extracted bite marks from the victim's body. Shoe prints, hair, and bite marks! The three cases were intricate and mysterious. What exactly was the connection between them?
