Chapter 113 The Different Fourth Dead

The crime took place at the pond next to the Lingnan Gymnasium, which is very close to the school bus stop and the MTR station.When He Jiahui arrived at the scene of the crime, the body of the deceased had already been fished out of the pond.

He Jiahui stepped forward and took a look, and found that the deceased was a middle-aged man in his 40s.His hands and feet were bound and a dumbbell was strapped to his leg.

"The deceased this time was a bit older. He was in his 40s, so he shouldn't be a college student!" He Jiahui thought to himself, and felt a little puzzled at the same time.

He Jiahui bowed down and carefully checked the condition of the deceased.

Around the mouth of the deceased, there are some mushroom-shaped foam, which is one of the typical appearance characteristics of the drowned.

During the process of drowning, cold water enters the trachea, which will stimulate the tracheal mucosa, causing the trachea to secrete a large amount of mucus, and then form fine and uniform white foam.Because these foams are rich in mucus and have high stability, they are not easy to break, and will eventually attach to the mouth and nostrils.

At this time, Ma Jun also came to the front.

"Has the identity of the deceased been confirmed?" He Jiahui asked.

Ma Jun nodded, and introduced: "After identification by the alumni, the name of the deceased is Cai Zhixiang, and he is the director of the Property Management Office of Chinese University."

"Cai Zhixiang? Which three words?" He Jiahui asked immediately.

"Cai is the Cai whose surname is Cai, Zhi is the ambition with great ambition, and Xiang is the flying Xiang." Ma Jun replied.

"These three words don't contain water!" He Jiahui frowned.

The names of the three deceased before had the five elements corresponding to the method of death. According to the order of the five elements, it was water's turn this time. The deceased indeed died in the swimming pool, but there was no water in his name.

Ma Jun said, "Not only did the deceased not have water in his name, but he was not a member of the student union. This is different from the previous three deceased."

"Where's Zhang Xingjie? Aren't we monitoring him 24 hours a day? Has he escaped our monitoring range?" He Jiahui asked.

"It was impossible for Zhang Xingjie to come and commit the crime last night." Ma Jun continued with certainty: "At about 10:30 last night, Zhang Xingjie was sent to the hospital because of acute appendicitis, and then underwent emergency surgery, so he kept In the hospital all night."

"In other words, the murderer this time is definitely not Zhang Xingjie." He Jiahui fell into deep thought.

Ma Jun continued to ask: "We have targeted Zhang Xingjie before, but this time Zhang Xingjie is absolutely impossible to commit the crime. What do you think of this case?"

"I think there are three possibilities." He Jiahui stretched out three fingers and continued; "The first possibility is that Zhang Xingjie is not the only murderer, he also has an accomplice, this time he is the accomplice.

The second possibility is that we have mistaken the target, Zhang Xingjie is not the murderer, and now the real murderer has come out to commit the crime again.As for the third possibility, someone imitated the crime. "

"Combating the crime?" Ma Jun frowned, and began to think about this possibility.

He Jiahui continued: "We can think of the five elements to kill people, and other people may also think of it. Then it is possible to take the opportunity to imitate the crime.

However, we did not announce the detection of sevoflurane in the bodies of the first three deceased?If it was an imitation killing, then the murderer this time should not know about heptachlorane.

So we only need to test whether there is sevoflurane in the body of the deceased to know whether this case is a copycat homicide. "

He Jiahui said, looked up and looked around, and then asked: "Is there any surveillance around here?"

"How can there be surveillance on the pond?" Ma Jun also looked around, and then said: "There is Zhongzhitang Restaurant and Chung Chi College next to it. I will send someone to take a look. I hope the surveillance there can capture the pond. The situation here!"

He Jiahui continued: "The murder case this time is different from the previous three times. This time there was no fire, no typhoon, and no rain. The traces left by the murderer should not have been destroyed. Maybe it can bring us new clues." .”

……

The forensic doctor took the deceased's body back for an autopsy, the forensic evidence also began to collect information on the scene, and the police began to investigate the deceased's interpersonal relationship.

After some investigation, Ma Jun brought detailed information about the deceased:

"The deceased Cai Zhixiang, 44 years old, was the director of the property management office of the university. He was married. His wife was a bank employee. The couple had a good relationship. They had a daughter who was in elementary school.

The financial situation of the deceased was normal. He and his wife took out a joint loan to buy a house and repaid the loan on time every month.Apart from mortgages and credit cards, the deceased had no other debts, nor had he ever borrowed usury.

In addition, there were more than 20 deposits in the bank card of the deceased. It can be judged that the financial situation of the deceased was good, and his death should not be caused by financial disputes.

The deceased did not have any bad habits. He did not gamble, buy horses, or do drugs. He occasionally bought Mark Six lottery with his colleagues, but he never won a big prize.

The deceased lived a regular life, commuting to and from get off work on time, and his daily interpersonal communication was normal, and he had never had any feud with anyone.His usual social scope is mainly in school. "

"It sounds like this Cai Zhixiang is an ordinary faculty member, and his life has no bright spots at all!" He Jiahui nodded irritably. The more ordinary people are, the more difficult it is to determine the direction of the investigation.

Ma Jun continued: "We have contacted the deceased's wife, and according to her confession, at six o'clock yesterday afternoon, she received a text message from the deceased, saying that she wanted to have a dinner with her colleagues, and there was no need to wait for her to eat.

At around nine o'clock in the evening, she received another text message from the deceased, saying that we would go to sing together after dinner, and asked her to go to bed first, so don't wait for her.

After receiving the text message, the deceased's wife called the deceased immediately, but the other party did not answer, but hung up directly, and then sent another text message saying that the phone was out of battery.

When it was twelve o'clock in the evening, the wife of the deceased called the phone number of the deceased again, telling her that the phone was turned off. The wife of the deceased thought that the cell phone of the deceased had run out of battery, so she fell asleep by herself.

This morning, when the deceased's wife woke up, she found that the deceased still hadn't come back. She called the deceased's mobile phone, which was still turned off, and called the deceased's office, but no one answered.After that she went to work, and she didn't know that the deceased had been killed until she received our notice. "

"Did the deceased's mobile phone be found at the scene of the crime?" He Jiahui asked immediately.

"You really got to the point right away." Ma Jun continued, "We found the wallet and keys on the body of the deceased, but we didn't find the deceased's mobile phone."

"Could it have fallen into the pond?" He Jiahui continued to ask.

"Someone has been sent to salvage it, but nothing has been found so far." Ma Jun paused, and then asked: "I also asked the deceased's colleagues, and they said that there was no dinner party last night, and everyone left after get off work."

"That is to say, the mobile phone message received by the deceased's wife was probably sent by the murderer. After get off work yesterday, the deceased was controlled by the murderer, and then the murderer used the deceased's mobile phone to send a text message to the deceased's wife.

In this way, the wife of the deceased thought that her husband had dinner and singing with colleagues, so she would not suspect that the deceased had an accident, and would not come to the school to find someone or call the police, and the murderer would have enough time to sink the deceased into the water in the dead of night pond. "

He Jiahui pondered for a few seconds, then asked, "Where is the monitoring? Has there been any monitoring to capture the situation of the pond?"

Ma Jun shook his head: "There is no surveillance in the pond, so we can only go to the buildings around the pond to check, but nothing is found. No surveillance camera will be idle to take pictures of the pond."

He Jiahui continued: "Did the surveillance of the nearby roads capture the deceased or other suspicious people passing by?"

Ma Jun still shook his head, and said helplessly: "It's not that you haven't been to Chinese University. There are not many monitoring systems installed there, and they are basically installed indoors. On the road outside, where are you?" There is monitoring for you to check!"

The density of public cameras in Xiangjiang is not high, and the Chinese University is built on the mountain. The government allocated the entire mountain to the Chinese University. Where there is a flat place on the mountain, a building is built. The roads in the university , were also excavated from the mountains and forests, and there was no surveillance coverage.

Ma Jun continued: "The forensic evidence collected footprints and a set of wheel marks on the bank of the pond. It looks like it was made by a suitcase. It is estimated that the murderer used something like a suitcase to transport the deceased. to the pond."

"Suitcase? This may be the direction of investigation. If the person pushing the suitcase can be found, there may be clues to the murderer." He Jiahui said immediately.

"This is also more difficult." Ma Jun continued: "The pond where the incident happened is next to the school bus stop of the Chinese University, and opposite is the MTR Chinese University Station. Almost every MTR station stops, there will be someone pushing luggage It is almost impossible to check the boxes one by one."

"Can the source of the dumbbells tied to the deceased's legs be found? The gymnasium is next to the crime scene. Could the dumbbells come from there?" He Jiahui asked again.

"The dumbbells are old, and it is impossible to find out the source through sales information. I also asked Cannon to check the gymnasium, and no dumbbells have been lost in the gymnasium recently." Ma Jun replied.

The two fell silent at the same time. Although it did not rain this time and found traces left by the murderer, these traces still could not allow the police to identify the murderer.

At this moment, Ma Jun received a text message on his mobile phone.

Looking at the information on the phone, Ma Jun said, "The forensic doctor has the results. The time of death of the deceased was between three and four in the morning. The cause of death was suffocation caused by a large amount of liquid entering the respiratory tract, that is, drowning. Moreover, sevoflurane residues were found in the body of the deceased!"

"That can rule out imitation." He Jiahui nodded solemnly, and continued: "Since sevoflurane was detected in the body of the deceased, it means that this is also a serial murder case, and the murderer is the same person, or same gang.

But the problem is that this case is quite different from the previous three cases.First of all, there is no water in the name of the deceased, which means that the murderer has changed the logic of the previous crime.

Secondly, the deceased was not a member of the student union, or even a student, but a faculty member.This is tantamount to the murderer changing his habit of choosing the target of the crime.This is not common in serial murder cases.

According to my previous inference, the murderer targeted the student union, and then chose people with the five elements of gold, wood, water, fire, earth in their names, and used the corresponding five elements to kill them, but Cai Zhixiang's death overturned these two inferences at the same time.

So I have a new idea, the murderer is not targeting the student union organization, but the individual, that is to say, the murderer is going to kill these four people, but the first three victims happen to be in the student union . "

Ma Jun thought for a while, and then said, "But we have checked the relationship of the deceased, and they have no enemies. Why did the murderer target the four of them in particular?"

He Jiahui answered: "Serial murders, if the crime is committed against an individual, there are nothing more than two situations. The first situation is that every dead person is related to the murderer, and the murderer has a grudge against every dead person. Kill them one by one.

The second situation is that there is a correlation between individuals.For example, a murderer will commit crimes against people with certain characteristics in specific weather, specific time, specific circumstances, or specific circumstances.

Just like the famous rainy night butcher case, isn't that the case?And this type of criminals often have psychological problems or antisocial personality. "

"You mean, these four dead are connected? This connection is the motive of the murderer?" Ma Jun thought for a while, and then said:

"It's okay to say that the first three deceased were members of the student union, but the fourth deceased was the director of the property management office. He has nothing to do with the first three!"

"This requires us to investigate!" He Jiahui paused, and then continued; "Although Chinese University has more than 2 faculty members, everyone is in the same school after all, so it can be regarded as bowing your head and not looking up. .

Will the life circles of the four deceased have a common point of intersection?Will there be business contacts between the student union and the property management office?These may all be the connection of the four deceased. "

"It makes sense, let's go, let's go to Chinese University again!"

With a new direction of investigation, Ma Jun immediately revived.

……

This time, He Jiahui and Ma Jun came to the property management office, where the fourth deceased worked.The person in charge of receiving them was a teacher surnamed Wang.

After briefly explaining the purpose of coming here, He Jiahui asked straight to the point: "Mr. Wang, will the usual work of your property management office involve the student union?"

Teacher Wang replied: "Our property management office is responsible for the property management of the whole school. In addition to the routine work of removing garbage, repairing facilities, and maintaining equipment, it also includes the approval of venues for on-campus activities.

For example, if an exhibition or award ceremony is to be held in the school, then our property management office will be responsible for preparing the venue for the event.

Another example is that if a student organization wants to hold an event, it also needs to apply for a venue from us. After we approve it, they can use the corresponding venue.

There are many student organizations in our Chinese University, such as various interest and public welfare groups, which of course also include the student union, and the student union usually holds a lot of activities, so they often come to us to apply for venues. "

"Besides applying for a venue, do your business have any other connection with the student union?" He Jiahui asked again.

Teacher Wang thought for a while, and then answered: "There should be none! Our administrative departments are all serving students and faculty members. Apart from normal property management and event venues, we can't provide other services. .”

"Mr. Wang, can you give us a copy of the application for the event venue in the past year?" He Jiahui asked again.

"No problem, we have archives of the use of venues for all activities in the school, and I will find them for you immediately." Teacher Wang replied.

……

After returning to the serious crime team, He Jiahui began to review the information provided by the property management industry department.

There are more daily activities held in CUHK than He Jiahui imagined, and most of them are spontaneously organized by student groups.

For example, the photography club holds photography exhibitions every month, the science and technology club often has robot competitions, and the drama club needs to rehearse every week, all of which need to apply for venues.

And the activities held by the student union are indeed the most. Almost every week, there will be a themed activity, and when it is frequent, there will be two activities a week.

Suddenly, a field usage information entered He Jiahui's field of vision.

"There seems to be a problem with the use of this venue!"

　The location of the crime was changed from a swimming pool to a pond. I checked the map and found that the location of the pond is a more suitable place to commit the crime.
