Wang Mengmeng's boyfriend was named Zhang Daqiang. He was extremely shocked when he heard that Wang Mengmeng had been murdered.
“How is it possible?”
“Impossible!”
When the police found Zhang Daqiang, he was booking a night with a few friends in an Internet cafe. Stayed for three days.
“The two of us had a quarrel. Isn’t it normal to break up after a quarrel? The two of us have been living together for more than a year. Everyone in the family has met. We originally planned to do it in the second half of this year. She went back to her hometown to get married during the Chinese New Year, so why did she..."
It turned out that according to Zhang Daqiang, he and Wang Mengmeng often quarreled, and they had quarreled and broke up before. This time it was mainly because Wang Mengmeng wanted to buy a new mobile phone, but Zhang Daqiang said that his mobile phone was still usable, so he didn't need to buy it for half a year until he returned home during the Chinese New Year holiday when the factory was on holiday.
In fact, Zhang Daqiang and Wang Mengmeng did not really break up. At that time, the two of them just had an awkward quarrel.
“He has a very good relationship with Liu Lingling. When the two of us had a disagreement, he went to live with Liu Lingling. We have done so several times. Liu Lingling and I also knew each other, but I didn’t give him a call that day. Liu Lingling is on the phone, behind I thought he had been living there.”
After Zhang Daqiang had a fight with Liu Lingling that night, the day before the incident, he left the house he and Liu Lingling rented and went directly to find two people. A friend went to an Internet cafe to stay up all night. This game lasted for three days. When the police found him, he was still playing games in the Internet cafe.
Zhang Daqiang knew Liu Lingling, Wang Mengmeng, and Zhang Lili. According to the police's prejudgment, the murderer might know three people, so the other party was suspected.
However, the surveillance in the Internet cafe showed that Zhang Daqiang never left the Internet cafe since he arrived, and there were network administrators and his friends who could prove it.
Zhang Daqiang did play in the Internet cafe for three nights and three days until the police came to find him.
There is a suspicion of committing the crime, but there is no motive and time of committing the crime.
At the same time, the Criminal Police Brigade’s on-site investigation has also made some progress.
At the crime scene, although not enough footprints, fingerprints and other valuable clues were collected, Lu Chuan found two footprints on the balcony of the room where the crime occurred that day.
Lu Chuan paid special attention to these two footprints, although from the footprints themselves, Lu Chuan could determine the approximate owner of the footprints.
But the relevant clues are not directly guiding.
Because it was not certain that these two footprints were left by the murderer, Lu Chuan gave the approximate height, weight and other characteristics of the two footprints and asked the Criminal Police Brigade to send people to all the rental houses. of men are screened.
However, no such situation has been found where there are people similar to the owner of the footprints.
I started collecting everyone’s footprints yesterday afternoon, and after comparing them for one night and half a day this morning, I found that none of the men in the rental houses matched the characteristics of this footprint.
After Lu Chuan got this information, he was not discouraged.
On the contrary, I am very happy.
Because if these two footprints do not belong to other male tenants in the rental house, then it means that these two footprints are most likely left by the criminal suspect.
And the other party actually left footprints on the balcony, which probably means that the other party entered the room through the balcony.
Sure enough, after having this suspicion, Lu Chuan took people directly to the crime scene for the second time at noon and made a discovery on the roof of the building.
The building where the crime occurred only has three floors. The room where Wang Mengmeng and Zhang Lili lived was in 303. On the roof facing this room, Lu Chuan and the others found two identical footprints and some traces of climbing. "It should go down from here."
Sun Biao said.
There are relatively fresh kick marks on the two footprints next to the edge of the eaves, and there are new friction marks on the waterproof paper above.
Based on these two footprints, Lu Chuan judged that the owner should be between 1.78 and 1.81 meters tall and weigh around 60 kilograms to 65 kilograms.
Wei Wei has some pigeon-toed legs, and the shape of his legs may be different from those of normal people. Wei Wei has some X-shaped legs, but they are not serious.
Just when Lu Chuan and the others were studying these two sets of footprints to identify the direction from which the other party came to the final rental house, Wang Zhaokai made a breakthrough in the investigation of the interpersonal relationship between the three people.
It turns out that about three days before the incident, Liu Lingling’s ex-husband came to Haizhou City to look for him.
“Bureau Lu, we just learned that Liu Lingling’s ex-husband came to Haizhou City from his hometown in the countryside a few days ago to look for Liu Lingling and want to remarry him. However, the two people did not reach an agreement after meeting and even quarreled. , Wang Mengmeng and Zhang Lili were by Liu Lingling's side at that time. Individuals even took action. Wang Mengmeng and Zhang Lili rented out Liu Lingling's ex-husband. Several people had conflicts a few days ago."
Not only that, Wang Zhaokai and another group of people were investigating the neighborhood. Another situation was discovered during road monitoring.
“When Liu Lingling and Zhang Lili left the rental house on the morning of the incident, they passed by the entrance of a supermarket. The supermarket had external surveillance cameras. We discovered that Liu Lingling’s ex-husband was actually present at the incident and had followed Liu Lingling that day. Two of them.”
"My suggestion is to conduct a focused investigation on Liu Lingling's ex-husband."
"After finding the other party in this way, first collect the footprints. I will make a comparison here to see if they are the same as the two found on the balcony. Are the footprints consistent?"
"Yes!"
Soon, Liu Lingling's ex-husband was found.
The other party did not leave Haizhou City, but found a small hotel not far from Liu Lingling’s rented house. When the police found him, Liu Lingling’s ex-husband was sleeping in the hotel.
Soon, Liu Lingling’s ex-husband Tang Jun was invited to the criminal police brigade.
Draw blood, collect fingerprints and make a footprint. After the process was completed, Tang Jun accepted relevant inquiries in the inquiry room.
“I didn’t go that day. Well, I just slept in the hotel. I wanted to remarry Lingling, but she didn’t agree with her going. I thought I would stay here for a few days, and then Tell her to consider the child. If you don’t consider me, what will happen when the child grows up?”
Chen Jiang raised his head.
"Tang Jun, I advise you to tell the truth. Where were you on the morning of May 12th? Was it in a hotel or somewhere else?"
Tang Jun continued without thinking.
"Comrade police, I'm not lying to you. I'm really in the hotel. If you don't believe me, ask the boss. I haven't gone out all day. I've been sleeping in the hotel." (End of Chapter)
