Thirteen murder cases left unresolved, and seven were solved within four days.
In any fingerprint battle, this is an extraordinary achievement.
And Lu Chuan's task in this fingerprint battle is essentially completed.
Among the remaining six cases, it can be confirmed that the same person is the murderer in two of them.
These are the murder of Detective Zheng Bin and the case of the female corpse falling from a building in Qingjian District.
These two cases can be combined for investigation.
Moreover, the murders were nine years ago and five years ago, respectively.
Who can guarantee that the murderer didn't kill again during this period?
No one can be sure how many lives were taken.
The case has been smoothly handed over to the Criminal Investigation Team.
Ren Qiang now has a massive headache.
Too much time has passed, and there are very few clues discovered.
Hard to manage...
Of course it's not easy, otherwise, it wouldn't have become a cold case.
