While waiting for the collection of physical evidence, Lang Heng accompanied Jiang Yuan, reviewing photos of various items of evidence with the onsite criminal police officers.
This case involved a large amount of physical evidence, and due to the difficulties faced by the special case team in the investigation, a large amount of evidence had been collected. However, after reviewing all the photos of the evidence, Huang Qiangmin had a realization and said, "The windows were all sealed shut, so the door was the only way in or out. The lock… can be said to be the key evidence."
As the long-standing captain of the Criminal Police Brigade, Huang Qiangmin had considerable experience with such homicide cases. He looked at Jiang Yuan with a hint of satisfaction.
