The two went back upstairs.
Guan Feng followed Lao Yang to the bedroom window.
Old Yang pointed to the markings they had made with a marker and said, "Look! The first fingerprint was found here."
Guan Feng looked at the black mark, frowned, and said, "The other party must have climbed up from here." He then stuck his head out to look at the lower part of the outer wall and asked, "Have you extracted any footprints?"
Old Yang nodded and said, "The drone found some climbing traces below, but extracting them is a bit complicated. We've taken some photos for now. Captain Guan, take a look?"
Guan Feng took the photo, carefully compared it with the shoe print pattern, and then nodded and said, "The shoe print pattern matches Li Yang's. It's hard to judge other aspects based on the photo alone, but the other party should have climbed up from here."
Old Yang said, "We'll set up the ladder here right away, and a more detailed footprint will be available this afternoon."
Guan Feng said, "I'll have it appraised again later."
As they talked, the two walked to the bedside.
Old Yang pointed to the bedside table and said, "This is the second fingerprint!"
Guan Feng stepped forward to examine it, recalling the marks left by Li Yang pulling open the cabinet door. He nodded and said, "It must have been left by him opening the cabinet door. But if that's the case, why would he climb overboard from the bedroom instead of the living room?"
“Normally, the first step for a burglar is to ensure their own safety and not be discovered by the homeowner. It’s rare to see someone like him who goes straight to the point.”
Old Yang pondered, "Perhaps he's afraid it will take too long? He's in a hurry?"
Guan Feng slowly walked to the window, looked at the latch on the window, and shook his head, saying, "I don't think so! A habitual thief like Li Yang would definitely do the details of scouting the place in advance and even making sure the owner is asleep. He must have calculated the timing as well. He wouldn't make such a mistake! Let's wait for the technical department to come up with the results and see when Nishimura Miko actually died!"
Old Yang nodded: "That's the only way."
Guan Feng patted Lao Yang on the shoulder and said, "Let's go downstairs and see what happened during their interrogation. Li Yang probably knows the answer to this question best."
The two went downstairs and heard sounds of interrogation coming from inside.
Guan Feng wanted to train a few people, especially Gao Dacheng, a "quasi" expert-level expert who was on the verge of a breakthrough, so he didn't go in to disturb them, but patiently listened at the door.
Seeing this, Lao Yang laughed and said, "Captain Guan, no wonder you are the youngest squad leader in our Hua'an. Putting everything else aside, your patience in training your subordinates is something other squad leaders should learn from. I'll have to spread the word when we get back; this is much harder than solving a case."
Guan Feng laughed and said, "Old Yang, stop making fun of me!"
Ten minutes later.
The details of the crime have all been clearly explained.
Since dropping out of school, Li Yang has become even more idle. During this time, he hooked up with a hostess at a KTV. In addition, he lost a lot of money gambling, so he thought of returning to his old ways, revisiting the campus, and setting his sights on these foreign teachers.
Foolish and rich!
This is Li Yang's assessment of these people.
In his words, he had stolen twice before, amounting to several thousand yuan, but these people were so careless that they didn't even realize their money had been stolen.
Upon hearing these words, Guan Feng led Lao Yang into the interrogation room.
Gao Dacheng and the others greeted Guan Feng when they saw him.
Guan Feng waved his hand and looked at Li Yang, asking, "Li Yang, why did you enter through the bedroom? Normally, if you're going to steal, the first thing you should do is make sure you don't wake the victim when you enter, right? Don't you think it's dangerous to enter directly through the bedroom?"
Li Yang said, "It wasn't that I wanted to enter from the bedroom! It's just that she had closed all the living room windows, and it was too much trouble to unlock them, so it was better to enter from the bedroom! Plus, I saw from the outside that she was already asleep, so I dared to climb in."
Guan Feng frowned and asked, "You said the lock in the living room is locked?"
Li Yang nodded and said, "Yes, otherwise why would I violate the principles of theft? Who would break into a bedroom directly? If that woke up the homeowner, it would be a big case!"
Guan Feng was surprised by Li Yang's answer.
He thought of Yoshiko Nishimura's pollen allergy.
If the other party closed the window or even locked it because of this factor, then it's understandable.
She was still worried, so she had air purifiers in both the bedroom and the living room.
These thoughts flashed through his mind, and then he asked Li Yang, "How did you know the victim was asleep?"
Li Yang said, "When I opened the window, the other person didn't move at all, not even with an expression. My intuition told me that she was fast asleep. When I went in, I smelled alcohol in the room, and I realized that she must have drunk a lot of alcohol and fallen asleep!"
Guan Feng asked, "You smelled alcohol? That means the room wasn't well-ventilated, right?"
Li Yang nodded and said, "Yes, the window was closed, but there was no latch."
Guan Feng asked, "When you went in, did you smell any floral fragrance? Like osmanthus?"
"The scent of osmanthus?"
Li Yang was taken aback, then shook his head and said, "I can't smell it!"
Guan Feng nodded, a bolder guess forming in his mind.
He said to Li Yang, "Any other details? About the victims?"
Li Yang thought for a moment, then shook his head and said, "Nothing much! It feels similar to other theft cases, except that she was sleeping very soundly, but otherwise there's nothing else."
Guan Feng asked, "This shouldn't be your first time burglarizing a foreign teacher's apartment, right? Which apartments did you burglarize before?"
Li Yang said, "There is one household on the second floor, which should be the next-door neighbor, and there is also one household on the third floor, so that's the two households."
Guan Feng said to Liu Shengguo, "Shengguo, you and Zhao Yang take the person back to the station and explain these things clearly. The others continue the investigation."
As they were talking.
Guan Feng's phone rang.
I received a call from forensic pathologist Lao Zhang. Through the autopsy, we found that the time of death was between 11 pm and 11:30 pm last night, and the direct cause of death was asphyxiation.
Guan Feng asked, "Old Zhang, could this suffocation you mentioned be caused by pollen allergies?"
Old Zhang nodded and said, "Yes! That's one of the possible reasons. If the pollen density is high, it may cause respiratory problems when you have an allergy."
Guan Feng said, "I remember there's usually an emergency medication for this kind of situation, right? You can spray it on and it will relieve the symptoms."
Old Zhang said, "Yes, there are usually β2 receptor agonists, beclomethasone, and budesonide nasal spray, so you can check the scene again to see if there is one or more of these drugs."
Guan Feng nodded, and after hanging up the phone, he asked Gao Dacheng, "Dacheng, did you find any pollen allergy medication at the scene?"
"hay fever?"
Gao Dacheng asked, "For example?"
Guan Feng then rattled off a series of drug names.
Gao Dacheng shook his head and said, "We found some roxithromycin and such, but we really don't have any of the spray you mentioned. Captain, it's really strange that you're saying this! It's pollen allergy season, and it's flowering season now, how could we not keep some of this kind of medicine on hand?"
