After thinking for a moment, Lin Lei turned his head and asked the Fujimoto police: "Fujimoto police, the forensic doctor of the Tokyo Metropolitan Police Department judged that the time of death of the deceased was between nine and ten o'clock in the morning, right?"

Fujimoto nodded and said solemnly, "Detective Lin, that's exactly the case. The medical examiner at the Tokyo Metropolitan Police Department uses the latest technology in the United States to determine the time of death based on the stomach contents. The last time the deceased ate was at 7:30 a.m. on the day of the killing, and during the meal, he was in the hall on the first floor, except for the hangover Takashima and the late Zhao Yi, everyone else saw ......"

Qiao Yan immediately asked, "Is it DSF technology?"

Fujimoto's eyes lit up: "I heard them say that it seems to be DSF technology. ”

Qiao Yan glanced at Lin Lei and explained: "DSF technology is the latest technology in the United States, and the time of death detected with this technology is very accurate. It is much more certain than the traditional detection of gastric contents to estimate the time of death. For example, the traditional method generally tests within 72 hours of death, and the final time of death is a presumed time. But the time of death derived by DSF technology is a definite time, not a speculation. ”

Lin Lei understood as soon as he heard it, today's technology is changing with each passing day, and technology is developing by leaps and bounds - it seems that Ms. Qiuike's death must have been within an hour between nine and ten o'clock, neither early nor too late.

"Who has an alibi?" asked Lin Lei.

Fujimoto replied, "Strictly speaking, there is no one. Because Hirota, Ito, and Kurokawa all went out before nine o'clock, but between nine and ten o'clock, they all came back. Hirota came back at nine-ten-year, and went out again at nine-twenty-point. Ito returned home at 9:30 and left at 9:45. Kurokawa returned home at 9:48 and left at 9:59. Several other people were in the apartment from nine to ten o'clock. ”

Lin Lei knew that the time Fujimoto said was verified through monitoring, and it was obviously very accurate. Lu Yun took out a small notepad at this time and wrote down the time when these people returned to the apartment and left. These time points are very important, and they may be important clues to solve the case in the future.

"Boss, judging from the current situation, when the murderer committed the murder, there was someone in the apartment!" Qiao Yan frowned and said.

Lin Lei nodded, took out a piece of chewing gum from his pocket, chewed it slowly, and said: "This shows that the murderer is an acquaintance, and the murderer was in the deceased's room at the time and did not make the deceased feel in danger." ”

Lin Lei was right, there were no traces of a fight at the scene, and as long as the deceased called for help, he would definitely be heard...... None of these are these, and the murderer should have been taken by surprise and killed with a knife.

Lin Lei walked into the apartment, and everyone rushed in.

302 The room where Ms. Qiu Chi was killed was cordoned, but Lin Lei did not enter the room, but looked at the entire apartment.

Each room 101, 102, 103 is a separate room with bathroom and shares a living room and kitchen.

Lin Lei walked into Zhao Yi's room 101 and smelled a smell as soon as he entered the door.

It's an indescribable taste, or to be precise, it's a mix of N flavors. That's what the scruffy boys' dormitory smells like.

Zhao Yi's socks were still littered everywhere, and the quilt cover had turned yellow and smelled musty. The ashtrays were full of cigarette butts, and the computer desks were full of stacks of take-out lunch boxes, some of which contained leftovers, and computer headsets were littered on them......

Obviously, none of this has been touched, and it has remained the same since the incident.

"Detective Lin, because the evidence in the case is not too sufficient, the scene is intact. Fujimoto explained.

Lin Lei nodded and hummed softly.

Lin Lei then looked at room 202 again.

That's right, room 202 is the room of the housewife Ito.

The dossier shows that the police made a major discovery in Ito's room.

Zhao Yi's shoe prints appeared in Ito's room, and in the bathroom basin of Ito's room, the victim's DNA blood stains were tested.

In this regard, the police believe that Zhao Yi wants to blame Ito.

The reason is very simple, if it was Ito who killed someone, how could she run to her room to wash her hands in Zhao Yi's shoes?

Do you know that there were people in the apartment at the time of the murder, and the murderer was covered in blood and swaggered from the first floor to the second floor in other people's shoes?

It's too dangerous!

A more reasonable explanation is that the murderer finished killing people and waited until everyone else had left before he came out of the scene and arranged the rest of the matter.

After 12 noon that day, everyone left the apartment, and Zhao Yi was the only one in the apartment all afternoon.

No matter how you look at it, Zhao Yi's suspicions are the biggest ......

Lin Lei then checked everyone's room, and there was nothing new.

After the incident, the police carefully inspected everyone's rooms and found no other clues related to the case.

Lin Lei came to the door of room 102 - this is the scene of the crime, the room where Ms. Qiu Chi was killed.

Lin Lei didn't mean to go in, but said to Qiao Yan: "I'll leave it to you here, we'll wait for your news outside." ”

Qiao Yan is a forensic doctor and carries a forensic suitcase with her.

Qiao Yan took a deep breath, nodded and said, "I understand, Boss." ”

She put on gloves, foot covers, and a head covering, and entered the scene with a suitcase.

Qiao Yan took out all kinds of the most advanced instruments in the suitcase and began to investigate the scene again.

Lin Lei waited quietly, looking at Qiao Yan intently.

Professional people do professional things, this is the principle of Lin Lei's work.

The scene of this case is very important, Lin Lei is not a forensic doctor, nor is he a fairy, he must let Qiao Yan investigate the scene and strive to find something.

After about an hour, Qiao Yan came out of room 102.

Without waiting for Lin Lei to ask, Lu Yun preemptively asked, "Qiao Yan, have you found anything?"

Lin Lei also set his sights on Qiao Yan.

Qiao Yan shook her head and replied with some frustration: "Boss, Sister Yun, there are no new discoveries, my investigation is similar to what the police wrote in the file......

After a pause, Qiao Yan continued: "But there is one thing that I think is a little strange, that is, that group of Zhao Yi's shoe prints are too abrupt. ”

"Abrupt?" Lin Lei's eyes lit up.

Qiao Yan nodded and replied, "The blood stains at the scene have been processed - there are traces of mop mops on the floor......"

Lu Yun immediately understood what Qiao Yan meant: "Since the murderer cleaned up the scene, why didn't he clean up the shoe print......s?"

Lin Lei's brows twitched slightly, and he was silent.

Fujimoto, who had not spoken, said: "We have also seen this point, and we believe that the murderer mopping the floor mainly to cover up the bloodstains, not footprints. There is a risk that the blood will leak outside and be found. ”

Lin Lei's eyes deepened......
