"This, I don't know." Su Tong was stunned, after seeing the video in the mailbox, she came in, and didn't call Xu Sa to ask too much, "What's wrong?" Did you think of something? ”

"No ......" Wen Yan frowned and shook his head, what Wei Sen said to him before made him always care about it, he thought that the tests that Wei Sen said were to let him help him cover up some evidence.

In the investigation of the case, he has not found any inevitable evidence related to Wei Sen, but now the appearance of the video has made him feel that the words Wei Sen said before are likely to have something to do with these videos, so he asked more.

Su Tong knew that he didn't want to say it as soon as he saw Wen Yan's expression, so he shook his head helplessly, "Wen Yan, we are friends, friends forever, so I will believe you no matter what." Investigating the case, I will persuade Xu Sa again......" After speaking, he left.

In the office outside, He Xingchen and Zhou Li were huddled in the corner, the two were still discussing the video just now, and when they saw Su Tong coming out of the interrogation room, they hurriedly got up.

"Officer Su, just now the person from Mr. Chen's side called, saying that the autopsy report of the body in the reservoir has come out, and he has a few questions he wants to talk to us." He Xingchen pointed to the phone next to him and asked, "Do you want to go, or will I ask them to wait until Team Xu comes back." ”

"No, I'll go right away." Su Tong didn't think about answering, turned around and went upstairs again.

The murderer committed four murders in just two days, and left very little evidence, how cautious and clever the murderer was.

If they don't catch the murderer from the only clues as soon as possible, I'm afraid they will fall into the hands of the murderer, which will make everyone's suspicion of Wen Yan even heavier.

Thinking of this, her steps upstairs were a little faster.

The forensic room seems to have a lunch break 365 days a year, and the forensic doctors can always be seen walking around in white coats.

Su Tong familiarly pushed open the door of Chen Lao's office, and saw that Chen Lao had just taken off the white coat on his body, and when he saw her, he only glanced at her lightly, and said lukewarmly, "The autopsy report is there, you can read it yourself." ”

Su Tong nodded to Chen Lao hurriedly, said hello, and picked up the information.

Compared with the previous two cases, although there is a lot of evidence that indicates that the murderer is the same person, the murderer has a very big change in the way he kills.

For example, in the first two cases, the murderer did it in the victim's home, and before killing the deceased, he tortured the victim in a cathartic manner, and his blood was everywhere.

But the later cases are different, although they were all drowned, but the traces of torture are significantly less.

She even had a special look at Lin Mei's corpse, except for some traces of struggle, there was nothing else on it, and it looked like the murderer was more like a cold-blooded killer with a clear purpose.

Chen Lao's autopsy report has always been written concisely and clearly, without superfluous nonsense, but this time, the autopsy report is surprisingly lengthy.

Su Tong glanced at Chen Lao strangely, did not speak, and his doubts were written in his eyes.

"Don't look at me like that, old man." As if he had expected her movements, Chen Lao said without raising his head, "There is a problem with this case, the body has been soaked in water for so long, and there are many conclusions that I can't confirm, so I can only put it forward for you, and you can consider it." ”

Chen Lao's skills are well-known in the city bureau, and allowing him to say such ambiguous words can only show that the evidence in this case is indeed very vague.

"Thank you, Mr. Chen." Realizing that things were more difficult than he imagined, Su Tong's mood became more and more heavy.

The autopsy report mainly analyzed the death of the corpse, and the column of the cause of death was the same as Su Tong guessed, saying "drowning", but in the confirmation of identity, it made her a little surprised.

"Elder Chen, what do you mean when you say you can't confirm the identity of the deceased?" Su Tong thought about it and asked, it stands to reason that the previous victims came to the city bureau to report the case, and the city bureau has collected their fingerprint records, and it should be very simple to check their identities.

But now they say they can't verify their identities?

"What else could it be." mentioned this old man Chen was angry, "The two victims are very similar in age and appearance, their fingerprints have been processed again, and their blood types are the same, except for DNA testing, there is no way to tell who is who." ”

"I have submitted the application for DNA testing, but there have been a lot of cases in the city bureau in the past two days, and the results have not come out so quickly, so I can only write this result for you."

The fingerprints on the hands of the corpses were processed? Why is that? Su Tong recalled the discussion with Xu Sa in the reservoir today, according to their previous guess, the murderer threw the body in the reservoir, which should be to lure everyone out of their serious crime team.

Since it is only for such a purpose, there should be no need to dispose of the fingerprints of the corpse, unless the other party has other ulterior secrets.

Suddenly, an idea flashed through her mind, Su Tong squeezed the hand holding the information tightly, looked at Chen Lao a little nervously, and said nervously, "Old Chen, I have another question for you......"

"What to ask and not to ask." Chen Lao was amused by her sudden seriousness, and said half-jokingly, "I treat you as half an apprentice." ”

Su Tong smiled reluctantly and asked the question in his heart, "Old Chen, will putting the corpse in the water affect the judgment of the degree of decay of the corpse?" ”

"Su Tong, are you suspicious...... Old Chen's expression froze, and he immediately understood the guess in Su Tong's words, "Impossible, the water in the reservoir does not contain special chemicals, and it has no effect on the preservation of the corpse." Moreover, I have also seen the corpse of Su Qing's girl, if there is her in those two corpses, I can recognize the old man at a glance. ”

"Su Tong, I know that your serious crime team wants to find Su Qing's body as soon as possible, but there are some things that can't be rushed." Chen Lao sighed and said meaningfully, "Many things still need to be fundamentally started. ”

After speaking, he went out with his purple clay pot teacup.

Su Tong stood in the office of the forensic office for a long time before going downstairs with the autopsy report.

What she didn't know was that in the short half hour she had been gone, there had been a mess downstairs.

Su Tong left with his front foot, and Xu Sa came back with his back foot, and the first thing he did when he came back was the formal interrogation of Wen Yan.
