crime profiler in the dark

Bai Haolin once again came to Baihu Park where the third victim of the serial throat cutting case was killed.

The victim of the third case was an unemployed and frustrated man. After he was fired by the company, he dared not tell his wife. Every day, he lost his life in a daze on the bench in Baihu Park, and the day he was killed was no exception.

In the first and second cases, the murderer chose a movie theater, and stepped on the spot many times in the early stage. Even though there were witnesses and surveillance videos in the movie theater, the murderer still avoided the monitor by "pretending to be a peacock" and leaving the safe passage. means to remove traces of oneself.The third case was the turning point of the serial throat-cutting case. The murderer moved the place of the crime outdoors, seeing that the victim was in a remote and unnoticed location, so he acted boldly, which was opportunistic.

Also starting from the third case, Bai Haolin entrusted Zhuang Xumao with full authority over the serial throat-cutting case because he wanted to investigate other cases. The murderer Wu Hua was caught by the profile of Zhuang Xumao who believed that the murderer had taken psychotropic drugs, which showed that there was nothing wrong with Zhuang Xusubaru's profile, and the case was officially closed after Wu Hua committed suicide by jumping off the building.

But is the case really closed?

According to Yi Yunzhao's investigation, Zou Jun had a very close relationship with Wu Hua, and he also admitted that he had met Wu Hua before his death. So was it Wu Hua or Zou Jun who committed the throat-cutting case?Or is it an alliance between the two?

With these questions in mind, Bai Haolin came to the scene of the crime in Baihu Park.

It is a bench on the tree-lined path in the park. The bench faces the lawn, which is more than ten meters wide, separating the park from the road. Behind the bench is a one-meter-wide walking path, with plants planted on both sides of the walking path. There are many trees, which can protect the surrounding area from the heat of the scorching sun, so many people like to run along this walking path.

At the time of the incident, it was around [-]:[-] in the morning, which was the rush hour for work. In the park, there were only some old people boxing, gliding, and playing chess in the open square. This pedestrian path was almost a vacuum. homicide.

According to the police's investigation in the vicinity, the murderer most likely entered the park from the northeast, and fled quickly from the west after the murder. Unfortunately, because there is no surveillance system in the park, it is impossible to know the murderer's appearance, and even a decent witness was not found. And because the style of this case is quite different from the previous two cases, the police also suspected that it was the same person.

It has been many days, and the park has long since returned to its former tranquility. Even though there have been murders here, it does not prevent a couple from making love to each other on the bench.

Bai Haolin took out his mobile phone, opened a map app, set the location, and entered the address of Wu Hua's home. It showed that Wu Hua's home was about 7.6 kilometers away from Baihu Park; followed by Zou Jun's home, which was 4.3 kilometers away.

The municipal construction of TMX City is in place, and there are many parks. There is a small park within 5 kilometers, and according to the map, there is a place 3 kilometers away from Wu Hua’s home; look at Zou Jun, although his home is far from Baihu The park is much closer, but one kilometer away from his home is the seaside boulevard, which is known as a holy place for horse racing. Running along the coastline is much better than circling in the park.

Bai Haolin himself has the habit of running. He will run 3 kilometers 4-15 times a week, and the time is about 80 minutes. The place where he runs is the park closest to his home. Would a professional with the purpose of all-Malaysia go to Baihu Park so far?

In addition, even if the murderer saw the opportunity to strike, it was absolutely impossible for him to see the victim for the first time. He must have seen him several times for many days and felt that there was an opportunity. Otherwise, who would wear a knife while running?

So it is certain that the murderer should live nearby, but it cannot completely rule out the suspicion of Wu Hua and Zou Jun.

etc!Bai Haolin suddenly thought of something, if the murderer is really Wu Hua, and he has the habit of running, then there must be signs of long-term running on his body!

Thinking of this, Bai Haolin was shocked and called the Forensic Medical Examination Office.

"Forensic Medical Examination Office." It was Qin Siye who answered the phone.

"Doctor Qin, I'm Bai Haolin, can you check for me the autopsy report of the suspect in the serial throat-cutting case?"

"Okay, what do you want to check?" Qin Siye's voice came from the other end of the receiver typing on the keyboard.

"Did you check his knee at that time?" Bai Haolin asked.

"Knee?" Qin Siye stopped typing on the keyboard.

"The murderer is a person who has the habit of running, and long-term running usually leads to damage to the knee joint. I would like to ask you to see if any injuries caused by running were found during the autopsy?"

"Uh——No." Qin Siye found Wu Hua's autopsy report, "Because the deceased committed suicide by jumping off the building after the police arresters entered, we just confirmed that he was not caused by external factors such as being pushed down. After falling from the building and proving that he committed suicide, he didn’t even do many routine checks.”

"Routine inspection? That is to say, no toxicology inspection?"

"Well, Haolin, is there a problem with this case?" Qin Siye noticed the surprise in Bai Haolin's tone.

"I can't tell if there is a problem right now." Bai Haolin naturally wouldn't reveal too much, "I remember hearing Dr. Jiang say that she used to leave autopsy samples for re-examination?" Most funeral customs in TMX City are cremation, Although the ashes can also be tested for toxicology, there are many limitations, such as whether the ashes are sure to belong to the deceased, whether there are other people's ashes mixed in, the evidence may be contaminated, and most drug poisons will volatilize at high temperatures, so the test is incomplete. And other factors.

"Yes, we keep a few hairs of each deceased just in case, do you need me to arrange a toxicology test?" Qin Siye asked.

"Okay, sorry to trouble you." Bai Haolin secretly lamented Dr. Jiang's meticulousness.

"Don't be polite to me!"
