Chen Tianbao is the janitor at the bank where the crime occurred.
During Song Mingguang's investigation of all bank staff's call records, Chen Tianbao's call records were under suspicion.
You need to experimentally verify that Chen Tianbao's DNA information and the DNA information from the short hair left by robber No. 1 are related by blood.
This discovery by Lu Chuan and his team is crucial.
"Should we make the arrest?"
When Lu Chuan made the call, Gao Xiang, the captain of Binzhou City's Criminal Investigation Team, was with Li Donglin.
"Of course, arrest him, immediately apprehend Chen Tianbao!"
Li Donglin decided at once, to immediately arrest Chen Tianbao.
"Lu Chuan, leave the work in the lab to others for the arrest; you are needed in action."
Although there has been some progress in DNA identification and comparison, that doesn't mean the subsequent work can stop; this is just one important clue, but may not be the only one.
