At the end of 1999, a series of killings occurred in Shijiazhuang City, Hebei Province and Taiyuan City, Shanxi Province. Killers wandered around these two places and killed 2 people in one month.

In p>1999, the police in Shijiazhuang City, Hebei Province received a report from the public that seven people from two families were killed in the same way in just two days. The victims were all killed by the murderer with a hammer from the back of the head. According to eyewitnesses, on the day when he saw a worker in overalls, such as a maintenance worker, holding a toolbox in the corridor, he knocked on the door in the name of account opening personnel and the warrant door, and then cut the signature list with a hammer by the head of the household to the victim's head, and then all the people at home.

When the police investigated the scene, they found that the cash and some valuables in the victim's home were missing, so the police concluded that the murder might be a burglary. The death in Shijiazhuang attracted public attention, and the police began to investigate the whole city. However, a few days after the investigation began, the same news came from Taiyuan City, Shanxi Province.

Subsequently, the same murder happened in Yuci, Shanxi Province. The murderer's modus operandi was completely consistent. The police concluded that the three men were the same murderer, and the three men * * * launched an arrest operation together. The three police stations also set up expert groups. First, they asked the witnesses in Shijiazhuang carefully, but the experts found that everyone's description was somewhat different. Some said that the murderer was round-faced, in his twenties, and was not tall. Others said that the murderer had a square face, was in his thirties and was more than 1.8 meters tall, which puzzled the police.

After constant comparison, the police came to the conclusion that it was working hours, the lights in the corridor were dim, and no one noticed the murderer very carefully, so there was a certain difference in judgment.

Then news came from Taiyuan City, Shanxi Province, and the murderer began to attack again. On the weekend morning, the boy's father is not at home, his mother is doing housework at home, and he goes out to play with the children around him.

while he was playing, he heard a lot of noise at home. He thought his mother had gone out. But Xiaobian's mother never made such a loud noise when she went out, especially when there were many old people living in the community.

He looked out from his neighbor's balcony and saw a man coming out of his house. He ran home and found his mother lying in a pool of blood.

The soldier told the police that he saw the murderer finally leave by bike. The police immediately checked whether anyone had lost his bike, but they didn't receive the report, so they concluded that the murderer might have a place.

The murderer is in his thirties, of medium build, about 1.75 meters tall, with sparse hair. He was wearing overalls and carrying a toolbox when he committed the crime.

These murders make the public panic. In order to solve the case more quickly, the Third Police issued a lot of announcements, hoping that the public can assist in the investigation and report suspicious people immediately.

this time, a lawyer called the police and told them that a client who came to consult him looked like the murderer they said.

The lawyer said that the day before, a man in his thirties came to his office and asked for some legal knowledge. The lawyer said that he was asked to come over the next morning to continue discussing the follow-up matters, but the man told him that he had something to do tomorrow and would come one day.

The next day, the lawyer's father was a doorman in the office and was brutally murdered.

Then the police collected fingerprints from the paper cup that the murderer drank. During this period, the murderer asked many questions about futures trading. The police thought he would sell it again, so they waited in the futures market.

After waiting for three days, the murderer Li Long was finally arrested.

After fingerprint comparison, Bruce Lee admitted his crime. He said that he owed a large amount of debt, and he was afraid of the constant demands of creditors, so he wanted to rob. After robbery and murder, he fell in love with this way to vent, so he started a series of crimes.

In August p>2, after trial, the suspect Bruce Lee was sentenced to death. Even if he was sentenced to death, he could not compensate for the deaths of 2 victims.
