Jiang Yuan opened his eyes and climbed out of bed, took a brief rest, and then hurried to the Criminal Police Detachment.
Upon entering the Cold Case Squad's office, he saw, as expected, that quite a few people had arrived earlier.
Wan Baoming had just come in from outside and, seeing Jiang Yuan, said, "Last night, everyone used the suspect information you provided to check through the missing persons. So far, no discoveries have been made, and today we're planning to conduct door-to-door checks."
"Do you think it was someone familiar who committed the crime?" Jiang Yuan asked.
Door-to-door checks, aside from inquiring about the situation, are most beneficial for observing family members' facial expressions and movements; some first-time killers, who initially act normally, can reveal themselves after just a few words.
