Chapter 661 - 605: Just Gutter Oil
Information about the members of the two tour groups, one large, one small, was delivered, and Jiang Yuan and the members of the Cold Case Squad carefully distinguished among them.
Discussing probabilities, the likelihood that people from the two tour groups chose to commit murder was extremely low. It was even less likely that they colluded with the victim’s ex-boyfriend, so, if a murder did occur, it would be a purely random act.
However, one had to admit that such low-probability events could indeed happen.
Jiang Yuan’s most dangerous crime scene investigation involved a case where the killer had joined a tour group and committed murders nationwide, also showing a penchant for returning to the crime scene. Jiang Yuan had almost become a prop for the criminal’s escalation. It was genuinely not for money, power, fame or profit, but purely for the thrill of killing, a purely antisocial personality, the so-called serial killer type.
Media reports of similar incidents can indeed be found, like a 10-year-old girl who, upon encountering a young child in an elevator, did not choose to help them home but instead inexplicably began to beat them, continuing until reaching the 25th floor, before throwing them down. There was also the 13-year-old who dismembered a classmate...
Random killings are inherently difficult to solve, and while a regular police team might not even consider this possibility, Jiang Yuan’s Accumulated Case Team had to.
Previous unsolved cases had contained such elements, which could not simply be dismissed as urban legends.
There were many ways of distinguishing, mainly questioning, taking fingerprints and footprints, along with collecting alibis.
These findings might not need to conclude immediately, but as long as they can provide effective evidence for later review, that was sufficient.
Just as the credibility of evidence in a research paper is questioned, so too is the strength of evidence. For example, an ordinary alibi such as sleeping with one’s wife at night is weaker because the wife might have a strong motive to lie for her husband. An alibi involving sleeping with a mistress is slightly stronger. If the alibi is sleeping with a time-based love experience provider at night, then the evidence strength becomes very strong.
