Hello, Miss Ann!

"Simon, the victim, was found by the park staff at about 11 o'clock last night at the riverside near the forest park. When he was found, the estimated time of death was between 3 and 6 hours, that is, between 5:00 and 8:00 last night.

Fu Hao, the victim, was found in the back street of Chinatown at about 10 o'clock last night. The bleeding volume of the wound was not large. The wound was sutured after operation. It is estimated that the time of the murderer's crime was about 2-4 hours, that is, between 6:00 and 8:00 last night.

Kendall, the victim, was found unconscious in the reference room of the hospital at 8:00 this morning. The victim is an ophthalmologist and basically does not need to stay in the hospital for night shift. Unless there is an operation, the victim did not have the operation yesterday, so the victim left after work at 6:00 p.m. yesterday. However, from the hospital monitoring, it was not found that he had left the hospital yesterday. It is likely that he has been in the hospital.

From the places where they found them, we divided them into point a (woods), point B (Chinatown) and point C (hospital).

ABC three points on the map presents an equilateral triangle, one point to another point, only 15 minutes drive, 30 to 40 minutes walk.

The three cases occurred at similar times. From the suture of the wounds of the dead and the injured, it can be seen that the same person did it... "

Bai Chun stands in front of the whiteboard. While he is explaining, his mobile phone shakes. He looks at it. It's an Jing's message.

"Back to the hotel, tomorrow morning there will be surgery, rest first! Don't be too tired. You will be lazy when you should be lazy, but remember to hide when you are lazy. Don't let the old urchin find out! good night! I love you. "

After reading the information, Bai Chun's mouth rose, but was soon replaced by a serious expression. He continued, "obviously, ABC's three points are not the first scene of the crime.

The police went to the victim's home and found a gas leak. They also found that the bathroom of the victim's home had been cleaned. A group of blood stains were found in the bathroom. After examination, it was the victim's blood.

Obviously, the victim's home is the first scene of the crime. "

Bai Chun pauses and writes A1, B1 and C1 on the whiteboard to mark the first scene of the three cases.

Bai Chun continued, "the victim Fu Hao loves mahjong. Every afternoon, he habitually goes to the mahjong hall near Chinatown to play mahjong, which ends around 5:00 p.m. but yesterday, his family found that the victim did not go home on time, so he began to look around 7:00 p.m. until about 10:00 p.m., someone found the victim unconscious in the back street of Chinatown.

The victim's home, the doctor's office, and the mahjong hall they often visit are all on the street next to Chinatown. The victim's home is in the opposite direction to the Chinatown back street, but why is the victim unconscious in the Chinatown back street?

The owner of the mahjong Hall said the victim left at about 5:30 yesterday afternoon.

At about 6 o'clock, the victim's Apprentice saw the victim passing by when he was proofing in the shop and was walking towards his home.

Therefore, between 6:00 and 7:00, the victim was arrested on the 100 meter street of the hospital's home, and committed the murder in a certain place near Chinatown, that is, circle B1.

When the typhoon came, it rained heavily and the number of people going out was less.

If the victim was not found last night, judging from the bleeding condition of the victim's wound at that time, in less than half an hour, the victim would die due to excessive bleeding.

Look at the other victim... "

Bai Chun pauses for a moment, drinks his saliva, clears his throat, and continues, "the victim, Kende, left work at 6:00 yesterday afternoon, but he was not found to leave the hospital. He was found at 8:00 in the morning. Judging from the wound situation of the victim, it was caused within 2-4 hours, so the prisoner committed the crime between 4:00 and 6:00 in the morning.

One possibility: the prisoner arrested kender after work and hid him somewhere in the hospital. After the completion of the other two cases, the prisoner returned to the hospital and attacked the victim again.

Maybe two: after two cases, the prisoner found the victim, committed the crime, and took the victim back to the hospital. "

"There is little difference between the two possibilities!" Some say.

"The difference lies in the different locations of the first crime! There is also the order first or last! " Bai Chun pointed to the triangle area of the map and continued, "now I set the target to a (Simon), B (Fu Hao), C (Kent).

If it is the first, the order of the crime is CBAC; if it is the last, the order is ABAC.

First: the prisoner starts from the hospital and starts to commit crimes one by one. First, he hides target C in the hospital, then finds target B to commit the crime. Finally, he finds target a dead at home and commits the crime, and then returns to the hospital to commit crimes against C.

The premise of CBAC is that the murderer may have an acquaintance with a, because there is no fighting trace found in a's family, so the acquaintance is more likely to commit a crime. Moreover, the murderer lives close to a, so the possibility of neighbors is high.

But there are some differences in ABAC's premise. The murderer and a and C are acquaintances, but the murderer's residence will be closer to C.

After: there are also two kinds of murders, 1. A, B, a, C; 2. B, a, CBai Chun looks at the people below with a puzzled expression, and draws several connection points on the whiteboard, "1. The murderer sneaks into a's residence, turns on the gas valve, and then finds B to commit the crime. After returning to a's residence to commit the crime, Bai Chun returns to a's residence to commit a crime.

2. After committing a crime to B, the murderer accidentally found a carbon monoxide poisoning and died, and then took a to place a to throw his body, and then found C to commit the crime.

However, the second possibility is very low, because a's residence is a two-story apartment. There is a large amount of carbon monoxide leakage on the first floor. The door leading to the room on the second floor is closed, and the bathroom is also in the room. Moreover, the doors and windows on the first floor are closed and the windows on the second floor are open, which is obviously the crime of the prisoners. "

"If we find out the order of the criminals, we can infer the general position and direction of the prisoners.

A's residence is close to San Francisco hospital and C's is close to general hospital.

If it's CBAC's crime order, it's very likely that the prisoner is a San Francisco hospital doctor.

If it's ABAC's crime order, the prisoner is a general hospital doctor.

The obvious characteristics of prisoners are: 1. Adult men, about 30-40 years old; 2. Doctors and clinical surgeons are more likely; 3. They are related to medical institutions; 4. They are acquaintances with the dead and the injured. "

Bai Chun pondered for a while and continued, "now, the criminal's motive is not clear. Revenge, interest, banter, or other motives are possible. As can be seen from the previous cases, the prisoner is an organized high IQ criminal. It's not difficult to find him, but it's hard to catch him... "
