"Perfume?" I frowned.

Jiang Tingbai nodded and said to me seriously: "I did smell a faint smell of perfume. ”

"Is it consistent with the perfume in Liu Xiaoqian's satchel?" I asked, a little excitedly.

Jiang Tingbai recalled it carefully, and a "hiss" sound came out of his mouth.

"I'm not sure, the heavy rain washed and soaked made the smell a lot lighter, but it is certain that there is a perfume smell, but whether it is consistent with the perfume in Liu Xiaoqian's satchel has to go back for testing." Jiang Tingbai was also a little unsure, and said lightly.

"A Huazi cigarette butt with the smell of perfume on it, does it mean that the murderer is a woman?" I thought about it and asked him suddenly.

"If the perfume is inconsistent with the one in Liu Xiaoqian's satchel, it can be proved that the cigarette butt came from a woman, but it cannot be ruled out that the murderer had perfume on his hands when he buried the satchel." Jiang Tingbai analyzed seriously.

After listening to him, I hurried up to his words and said my thoughts: "So at least one thing is certain, this cigarette butt was left by the murderer after burying Liu Xiaoqian's backpack." This also shows that the murderer left from this road after helping Liu Xiaoqian commit suicide! ”

Jiang Tingbai stopped, looked at me with a very serious expression, and at the same time let out a very deep voice: "So, the murderer came by car." ”

"That's right, the murderer went down the mountain through this road, and since the cigarette butts can be thrown here, it means that the murderer's vehicle must have been parked at the foot of the mountain!" After I finished speaking, I looked back in the direction we had come, and the police car we had parked at the foot of the hill.

"It's too much of a coincidence, it was raining heavily, and the murderer drove here and met Liu Xiaoqian, who wanted to commit suicide?" Jiang Tingbai looked at me in disbelief.

"There may be another possibility that the murderer was called by Liu Xiaoqian, but we investigated Liu Xiaoqian's mobile phone and did not find out who she had contact with yesterday." After I finished speaking, I added: "Maybe I contacted and deleted the chat history...... I hope that the Technical Investigation Department can fully restore the clues in Liu Xiaoqian's mobile phone. ”

Jiang Tingbai nodded, and I took the technical team and continued to walk towards the upper reaches of the Qinghe River.

After walking for about five minutes, we saw a gazebo in the distance. However, there is no concrete road leading to the gazebo from us, which means that we have to walk through the woods to get to the gazebo.

This is the reason why we did not investigate the cement road in the first two investigations of the crime scene.

The technical team immediately carried out on-site investigation work on this forest.

A short time later, I received a call from the Technical Investigation Section.

"Brother Qin, my side has completed the restoration of the mobile phone information, the content of the social software is still being recovered, and I have temporarily restored the browser access records that he deleted." Xiao Xuan's somewhat immature voice came from the phone.

"What webpages has Liu Xiaoqian browsed?" I asked immediately.

"It's all suicide pages, I'll take a screenshot of it for you and send it over." On the phone, Xiao Xuan hesitated for a moment and said slowly.

A minute later, Xiao Xuan sent me a screenshot of Liu Xiaoqian's mobile phone browser access record.

The above one blew my mind:

What way to commit suicide without pain?

Are sleeping pills available at pharmacies?

Does it hurt to cut your wrists?

How many floors can you fall to your death by jumping off a building?

Arsenic.

What are the most effective ways to commit suicide?

……

I looked at the pictures on my phone, and my heart trembled a little, because the time span of these browsing traces is very long, the earliest one was half a month ago, and the most recent one was the day before Liu Xiaoqian's death.

She looked up so many suicide-related pages, which showed that she didn't want to live for a long time.

This also further proves that this case is a suicide case, except that a second person appeared to help her complete the suicide.

"Such a young girl in the flower season chose to commit suicide so resolutely, her heart must be very desperate." After I finished browsing the pictures that Xiao Xuan sent me, I took a deep breath and slowly closed my eyes.

"Old Qin! There are footprints here! ”

A call pulled my thoughts back, and when I looked back, in the woods around me, Jiang Tingbai was waving to me.

I hurriedly walked into the woods and walked briskly in the direction of Jiang Tingbai: "There are footprints?!" ”

"Look!" Jiang Tingbai pointed to the ground and looked in the direction of his finger, and sure enough, there was a footprint.

It's just that this footprint is very shallow, but judging from the formation of the footprint and the collapse of the soil, the soil here was very wet when this footprint was formed.

In other words, this footprint was formed in the rain.

The technical team immediately collected the footprints and expanded the search area to continue searching for other clues.

"Great, if there are footprints, it will be of great help to us to lock up the suspect." I couldn't suppress the joy in my heart and said with a smile.

Jiang Tingbai also breathed a long sigh of relief, and said slowly: "Now that there are footprints, it means that we have traces to follow, plus the Huazi cigarette butt that I just found on the side of the road, there are more and more clues." ”

I nodded vigorously and said seriously: "This is indeed good news, my intuition tells me that we are getting closer and closer to the truth of Liu Xiaoqian's suicide case." ”

"That's right." After Jiang listened to Bai, a look of bitterness suddenly appeared on his face, he looked at the footprints on the ground, and said slowly: "It would be good if Zhang Mengyu's case could also have clues, after all, this is a suicide case, even if it is to help commit suicide, but Liu Xiaoqian's subjective willingness to commit suicide is very strong, and the final court verdict will not be particularly heavy." But Zhang Mengyu's case is an outright homicide, and the murderer's methods are extremely cruel. ”

"Zhang Mengyu, alas, ......"

I was also a little lonely by Jiang Tingbai's words, Zhang Mengyu should have a happy family, and there is about to have a happy wedding, but now everything is gone.

Thinking of this, the joy of discovering the clues just now was swept away in an instant, and I began to worry again, because there was still no clue in Zhang Mengyu's case.

Xue Hang and Li Meng have been out to investigate for two days, and so far they have not sent back any valuable clues.

"The case is investigated, not out of thin air, don't think so much about it first, first investigate the case of Liu Xiaoqian's suicide, and then go back to investigate Zhang Mengyu's case, not to mention that Li Meng and Xue Hang haven't been following up." Jiang Tingbai smiled faintly and comforted me a few words.

Our third investigation of the crime scene can be said to have gained a lot, footprints, Huazi cigarette butts, and perfume smells are all clues that we can investigate.
