In the information age, the power of public opinion is increasingly strong. It can both drive social progress and potentially push a legal case into an abyss. High-profile cases often focus on social hotspots, public concerns, or emerging issues, establishing rules of conduct through judicial rulings and guiding the public to form correct values and a belief in the rule of law.
The Brighton Truck Murder Case (1934)
This is one of the most mysterious murder cases. It should have been solved, but it remains a mystery to this day. On June 17, 1934, a strange smell emanated from a truck parked near Brighton train station, arousing suspicion. Police found a woman's body inside; she was in her twenties, and judging from her clothing, she was clearly from high society and three months pregnant. Despite the efforts of police throughout Britain, the victim's identity was never confirmed. Olive oil was applied to her body to prevent bleeding, suggesting the murderer was medically savory. Evidence indicated that the truck had crossed London Bridge. Police investigated for many years but found no clues about the murderer or the identities of the victims, even though both may have belonged to the "leisure class." The inability to identify the victims was particularly discouraging. Later, the case was described as a "perfect murder."

The Thames Nude Corpse Murders (1959-1965), London, Thames River
Newspapers referred to the perpetrator as "Jack the Stripper." These cases occurred in London between June 1959 and February 1965. All the victims were prostitutes, and all had been strangled to death. There was persistent speculation that the killer was a well-known boxer, Fred Mills, who also died shortly after the murders were aborted. The killer apparently acted alone, driving a caravan through London. In one case, police traced the location where the bodies had been placed—a warehouse in an industrial area of London—but the trail went cold. The sheriff in charge of the case, John Ross, firmly believed the killer had committed suicide after the final murder. He had also hinted that the killer's identity had been confirmed, but the case remained unsolved.

The Nanjing University Dismemberment Case
Also known as the Nanjing "1.19" Dismemberment Case or the Diao Aiqing Case, the incident occurred on January 19, 1996, in Nanjing, Jiangsu Province. The victim was Diao Aiqing, a first-year female student at the Nanjing University's Continuing Education College, who was brutally murdered while still at the university. To destroy evidence, the killer cooked Diao Aiqing's body and cut it into more than 2,000 pieces. Nine days after her disappearance, on the morning of January 19, fragments of the victim's remains were discovered by a sanitation worker on Huaqiao Road in Nanjing. Following the incident, the Nanjing Public Security Bureau conducted a large-scale search, but the killer was never found.

The Zodiac Killer
The Zodiac Killer (also known as the Zodiac Sign Killer or Zodiac Maniac) was a serial killer who committed numerous murders in Northern California during the late 1960s. Until 1974, he sent numerous provocative letters to the media, signing them. These letters contained four coded or encrypted messages, three of which remain unsolved. The Zodiac Killer is known to have murdered five people between December 1968 and October 1969 in Benicia, Wariho, Lake Boyesa, and San Francisco. His targets were four men and three women aged 16 to 29. Several other murders have also been suspected of being committed by the Zodiac Killer, but conclusive evidence remains lacking. The San Francisco Police Department initially placed the investigation inactive in April 2004, but reopened it sometime before March 2007, and the investigation remains ongoing.
