He died for a month without anyone noticing. His children send money abroad on time, thinking he is still alive. The murderer thought he had done a clean job - the body was highly decomposed, the scene was destroyed, and there was no identifying information. But he left something behind. A trace of skin between fingernails. The soles of the shoes should not appear clean. Inside the lining was a small ticket that was so bad that it couldn't be seen clearly. Serious Crime Team 5 took over. Captain Lin Shenjian judged from the dust on the soles of his shoes: This was not the first scene. Forensic doctor Jiang Ling locked the murderer's DNA from the cracks of his fingernails. Technology Tang Mian uses a piece of fiber and a small ticket to spell out the last 48 hours of the deceased. Action Yan Wugui completed the arrest in 30 seconds. Deputy team leader Wen Ruyu spent three days weaving a web of evidence. Five people, five professions, one truth. A corpse doesn't lie, but someone needs to speak for it.
