"Stop!" Su Tong's face was pale, and he made a gesture at him not to come over, "I believe you, don't come over!" ”

Until now, she still felt the urge to vomit when she remembered the situation that day, and she didn't want to really vomit on the spot.

Xu Sa took out a plastic bag from the pocket of his coat, carefully put the soil in, and then turned the surrounding soil around it along the pit where the body was dug up.

Everything smelled and he felt that there was something wrong with it, so he put it in the evidence bag, and was ready to take it to the appraisal department after returning to the city bureau for firmness.

Su Tong looked at his serious expression, he didn't want to stand still, but he didn't want to touch the soil, so he simply went around to see if he could find some other clues.

The two did not discuss a word during the period, but they performed their duties and cooperated very tacitly.

Two hours passed in a flash, Xu Sa collected several generations of sample soil, and Su Tong also found some suspicious traces in the forest.

"On the left side of the forest, there are several traces of dragging, I suspect that the murderer left a ...... when he brought the three deceased to this place" Su Tong showed the photo he took to Xu Sa,

"I heard from the captain of the second team that when they dug up the three victims, the three victims were lying in the pit side by side." Su Tong gestured, "This also shows that the murderer buried the three victims in this place at one time, without doing separate treatments." If you look at this mark on the photo, both in terms of width and depth, it looks like three people being pulled side by side......"

Xu Sa didn't pick up her phone, just tilted her head and looked at the photo with her movements, "Are you sure that the murderer dragged the three victims here side by side?" ”

"If you think about it, the three victims are all men, and they have been kept in captivity for a period of time in front of them, and their weight has also decreased, but the weight of the three adult males is still not to be underestimated."

"At least, I can't do it, and I have to pull three big men side by side to this far......"

Moreover, the victim will have to dig a pit and bury people in the future, unless the victim's energy is very strong, otherwise this will not be possible at all.

Su Tong was stunned, and felt that Xu Sa had some truth in what he said, "But this trace appeared in the forest, don't you feel suspicious?" If it wasn't the killer dragging the victim to leave a trace, what could it be? ”

When she saw this trace behind the forest just now, she had a feeling that this trace must have something to do with the case.

"Well, I don't know yet." Xu Sa groaned slightly, "In this case, you immediately make a call to the trace examination department and let them come and take a look." ”

"Also, if the two of us guess this thing, I don't know what year and month it is." Su Tong shrugged his shoulders and called honestly to inform the people in the trace examination department.

After the two surveyed the scene, they decided to go back to the bureau first, meet Wen Yan's side, and see if He Xingchen's investigation of the camera had any results.

In the car, Su Tong closed his eyes and pretended to sleep.

Speaking of which last night she was on vacation, only she knew that she watched the surveillance video for most of the night, and did not fall asleep until it was almost dawn.

Today, she ran outside all day, and it was not easy for her to survive until now.

Xu Sa didn't bother her, only turned up the air conditioner in the car a few degrees, and turned on the music, so she concentrated on driving.

Not long after they returned to the city office, lightning and thunder thundered in the sky outside, and it rained heavily.

"Is this weather also to match the current situation of our Serious Crime Team?" Zhou Li leaned against the window, "We are all about to die of worry about these cases now, and we don't know when the rain will pass......

"Now that the rain is falling, it won't be too far from the sunny day." Xu Sa walked in slowly with his hands in his hands and glanced at the situation in the office, "Yes, everyone is here." ”

"Boss! I have important clues to say! As soon as Chen Hui saw Xu Sa, he walked over quickly with the documents he wanted from the First Mental Hospital, "It's about the deceased's ex-boyfriend I was investigating, I found out that that person lived in the ward next door to Qin Jun when he was receiving treatment, and the two had contact in their usual activities!" ”

Xu Sa and Su Tong's hearts were at the same time, this was not good news to them.

Xu Sa turned the documents in Chen Hui's hand and looked at them silently.

In the document, in addition to the case, there are also screenshots of some surveillance videos, from which he can clearly see that Qin Jun is talking to a man with his head down.

I thought that the expressions of the two people looked a little abnormal, so this picture looked a little scary.

"This Qin Jun, shouldn't he really be a murderer?" Everyone who heard everything looked at each other, and they all felt that their worldview was refreshed.

Can a mentally ill madman really accomplish such an elaborate murderous plan?

"Theoretically, it's possible." Wen Yan suddenly spoke up, "I have seen Qin Jun's case and communicated with him, he only has some mental problems, but his cognitive ability to the world and his ability to act are normal. ”

This is also the reason why Qin Jun would say something that sounds inexplicable but is actually very logical.

"Then, will we continue to investigate this case?" Zhou Li looked at Xu Sa blankly, and then looked at Wen Yan.

Since the murderer is Qin Jun, wouldn't it be over if they directly asked Sun Ju to interrogate him?

"Check!" It was not Xu Sa who answered, but Su Tong.

"Everything Wen Yan said is only theoretical, and the reason why a theory is called a theory is because its implementability is uncertain." Su Tong took a deep breath and said slowly, "And those paintings found in Qin Jun's ward, as direct evidence, I always think that there is something in them that we haven't found out yet." ”

"So, no matter whether Qin Jun is a murderer or not, as long as there is any suspicion, we will investigate! We can't let go of any murderer, but we can't blame any good person! ”

Even if there is a little bit of evidence that proves that Qin Jun may be innocent, then she must insist on investigating.

Su Tong's words fell, and everyone looked at her in a daze, and then under Xu Sa's leadership, a loud applause rang out.

"Officer Su, that's a good point!" He Xingchen, who didn't know when he came over, looked excited, "What you just said, can you say it again in a while?" I want to copy it down as a warning for me in the future! ”

Su Tong's face turned red with embarrassment, "I'm just talking casually, everyone is taken seriously......"
