Chapter 807: Investigating the Murder Weapon

"If the perpetrator is one individual, then our prior investigative direction has been completely wrong."

Lei Xin's frustration flashed and was gone. Being an experienced detective himself, he knew that mistakes were part of the norm.

Most investigations are a matter of trial and error; no one can claim a hundred percent certainty in cracking a case. Niu Tang, the forensic doctor from Qianjin District, was also skilled. His performance in past homicide cases had been noteworthy, particularly when it came to the identification of various paper materials. Niu Tang could even be considered a master in this area, with technical investigators from many provinces and cities traveling long distances just to have Niu Tang personally conduct a paper examination.

That three different wound patterns could be made by a single knife was a conclusion only a forensic expert like Jiang Yuan would dare to make from just looking at the photographs.
