The dusty past of the first criminal investigation department

Feng Chen nodded, then thought of another thing, and said, "Has Shi Tianhai's wife sent someone over to look at it?"

An Mu nodded, "After knowing what happened to Shi Tianxing, I called someone to go over."

Then Feng Chen talked about how Shi Tianxing was hanged from a tree by the murderer, all three of them had "wow" expressions on their faces.

Qin Yang shook his head, "Impossible, even if the murderer crushed the branches with stones in advance, then tricked Shi Tianxing to the edge of the cliff, strangled him with a rope, and pushed him down. He hung it on a tree branch and was restoring the branch. Although this method is feasible, ordinary people would not approach a place like a cliff. How did the murderer trick Shi Tianxing to the edge of the cliff? How about pushing him down?"

Feng Chen thought about his experience of being pushed down yesterday and said: "It's simple, the murderer just let him see what is under the cliff. When I saw Shi Tianhai's body, I was thinking, why did he dig a hole to put the Bury him in. Snake Immortal's revenge is pure nonsense. He knows that he is going to die and bury himself in it is even more impossible. If he knows that he is going to die, he must call 120 immediately. I think Shi Tianxing and Shi Tianhai must They were looking for something, and the thing was in the hands of the murderer. So digging a hole and looking down the cliff were all ordered by the murderer."

Bai Luo's eyes lit up, "I know, it's the snake fairy's corpse."

Feng Chen nodded, he thought so too.

At this time, Bai Yumo walked in, "I have checked all those things. First, the wooden box is very clean without anyone's fingerprints. The murderer should have wiped off the fingerprints on the wooden box before throwing it away; second, A small amount of blood was found on a section of the rope, which was not Shi Tianxing's. This kind of straw rope is prone to barbs, which may be left by the barbs piercing the murderer's hand; third, Xiao Li from the third department said today When packing Shi Tianhai's body bag, I found a drop of mercury inside."

Qin Yang: "Mercury? Isn't mercury highly poisonous? Could it be that the murderer wants to poison Shi Tianhai to death with mercury?"

Bai Yumo explained: "No, mercury poisoning is generally chronic. Acute mercury poisoning can only be caused by inhaling a large amount of mercury vapor in a short period of time. Death. Moreover, mercury is a toxic heavy metal, and it is impossible for ordinary people to get such a large amount of mercury."

Qin Yang nodded, so it is so.

An Mu thought for a while and said, "Maybe the murderer is as unaware as we are. When it comes to mercury, the average person's reaction should be poisonous. Isn't there mercury in the thermometer? Just buy a few more thermometers."

Bai Yumo blinked, "This possibility cannot be ruled out."

"Ah..." Bai Luo yelled loudly, and several people jumped.

Bai Yumo: "What's wrong?"

"Look," Bai Luo said, pointing to the playing video, "this person is not Shi Tianhai!"

Hearing Bai Luo's words, several people quickly gathered around,

Bai Luo played back the video for everyone to see, "I just thought it was weird, Qiu Feng's ward is in the middle of the building, next to a staircase, the elevator is on the far right of the corridor, and the camera is installed above the elevator, Shi Tianhai Every time I take the elevator up and down the stairs, only one time after one o'clock in the morning, I actually took the stairs, and I used the stairs to go up and down the stairs. So I checked it a few times, this person looks very similar to Shi Tianhai, The jacket is also the same style. I didn’t notice it at first, but I found it after a closer look. When this person left, the door of the opposite ward just opened, and you can see that the shoes on this person’s feet have reflective strips, which should be sneakers, flats Shoes and the like, if I remember correctly, Shi Tianhai should be wearing a pair of leather shoes."
