On the evening of the 16th, Officer Cao sat in his office, looking at the DNA comparison report in his hand and fell into deep thought, sending samples for testing: hair, blood type: type O match 100%, and the sample matched 100% with the deceased's DNA.

Clips flashed in my mind such as visiting Zheng Jun's residence, dumping the body, and identifying the body, and a name kept appearing in my mind: Lin Ling.

After the identity of the deceased was confirmed, the police officers checked Zheng Jun and Lin Ling's call records, WeChat records, online shopping records, ID cards, accommodation registration, and ticket booking records.

Zheng Jun has a complicated social relationship, has a wife, a lover, in addition to a lover, he also has an ambiguous relationship with a female colleague and a female student.

And Lin Ling is simply a blank piece of paper, there are no colleagues who are too close, only one best friend, that is, Wu Fang, who accompanied her to identify the body, most of her parents and relatives are in her hometown, she doesn't talk about WeChat, and rarely calls. This veritable Mrs. Zheng lives a pure-hearted life with few desires, neither greedy for material things and spending money, nor fond of vanity and showing off her wealth.

The intuition of the criminal police for many years always made him feel that Zheng Jun's wife, a woman named Lin Ling, was a little strange, but he couldn't tell what was strange. If social relations are so simple, what is her time for? Wash your hands and make soup, do laundry and clean up the house?

Everywhere polite, well-behaved, and calm, even if he knew that his husband was murdered and saw the tragic situation of the charred corpse, he was restrained in his grief, and he was not overly out of shape.

Since he was so calm, Officer Cao had the ugly scar on Lin Ling's wrist in his mind...... Self-harm? What caused her to harm herself?

Officer Cao rubbed his temples, got up and paced to the window, looking at the bright lights of M City, the lights emitting a warm and penetrating light, and in the shadows that were not illuminated, crimes might be happening.

At this time, the phone in the office made a noisy and piercing sound, tearing apart the silence of the night, Xiao Wang on duty picked up the phone, and his expression became more and more serious: "Female corpse? What is the specific address? Okay, don't lie, protect the scene, we'll be there right away. ”

"Team Cao, Room 1602, Unit 2, Building 5, Lido International, found a female corpse"

Lido International? Officer Cao repeated, by the way, in Zheng Jun's wallet found at the scene of the dumping of the body, there was a supermarket receipt, Wumart Supermarket Lido International Branch. The shopping time was two months ago, and I wondered at the time, the supermarket will definitely be visited in a week or two, who keeps the shopping receipts two months ago?

Officer Cao and the police officers rushed to Lido International, quickly evacuated the crowd of onlookers, pulled up the cordon, and asked the security guards about the specific situation.

"Officer, my surname is Wang, is the security guard in charge of this building in this community, you also know that this is a high-end community, come out and go in to use access control, these days the residents of the 16th floor reported that there is a smell, we cleaned up the garbage in the corridor and the door, or more and more smelly, neighbors repeatedly complained, we came up to check again, found that the smell was emitted from room 1602, knocked on the door and no one opened, found the tenant's contact information from the property, dialed over, no one answered. In desperation, we opened the door with the spare key of the property, and as a result, "The security captain said this, stammering.

"Don't be afraid, speak slowly," Officer Cao comforted.

"Officer, I pushed open the door and there was a foul smell, I walked in and took a look, I saw, I saw, I saw, there was a corpse lying in the bathtub in the bathroom, it was too scary, a jar of water was black, red, black, red, stinking, black and red hair was sticky, sticking to the rotten face, all rotten, black and red skirts" Captain Wang spoke incoherently, and when he said this, he glanced at the direction of the room with palpitations. It looked as if a corpse would run out and strangle him.

Officer Cao arranged for the police officers of the Technical Section, the Trace Investigation Section, the Forensic Medical Team, and the Criminal Investigation Team to carry out an orderly on-site investigation at the scene of the crime, collect evidence, obtain surveillance video, and visit and investigate the surrounding neighbors, supermarkets, properties and other places and personnel related to it.

On the afternoon of the 17th, Officer Cao got the autopsy report, summarized the results of everyone's investigation in all aspects, and immediately held a case analysis meeting.

"Two bodies were found in our city one after another, because the two deceased had an intersection before their deaths, the two cases have been officially merged into a serial murder and cremation case, the superior leaders attach great importance to it, we are limited to solve the case in a week, and today we will convene an emergency meeting, let's summarize clues and re-sort out the case." Officer Cao said solemnly

"Team Cao, the colleagues who stayed at the scene this morning to investigate found a secret compartment behind the deceased's bedside painting, which contained a warehouse lease agreement and key, which Li Wenwen signed a month ago. Xiao Wang and Xiao Zhang are rushing to this warehouse in the southern suburbs of M City. ”

Officer Cao looked at Xiao Liu with a smile, with praise and affirmation in his eyes, Xiao Liu was very useful, and he was encouraged and continued with confidence:

The identity of the deceased has been confirmed, Li Wenwen, female, 24 years old, came to M City three years ago, worked as a front desk in an advertising company, because of her good image, there is no shortage of men to pursue, and the relationship between colleagues is average, especially female colleagues have a sense of distance from her, may usually be too ostentatious to show off their wealth, and they are fashionable and love to dress up, so female colleagues are jealous of her" Xiao Liu said this, glanced at Xu Ran, and sure enough, he saw Xu Ran with a disdainful expression, in the rental room, Xu Ran saw that the deceased had such a brand-name bag, luxury goods, Rolling his eyes, he said that the deceased must be a junior, or the mistress of an official, a woman, she is so jealous!

"The deceased lived alone in Lido International, the rent was paid annually, the deceased pursued material enjoyment during his lifetime, eating, using, wearing, and wearing famous brands, and her front desk salary was unaffordable" Xiao Liu paused when he said this, and emphasized: "Someone must fund her"

Officer Cao nodded and asked the forensic team, "Is the time of death and the cause of death determined?" ”

Officer Zhang of the forensic medical team said: "The time of death of the deceased was seven days ago, that is, around May 9. This is close to the time of Zheng Jun's disappearance and murder, and Zheng Jun's lover is the last person we know of to see Zheng Jun, and the time was 8-9 a.m. on May 8. Because Zheng Jun's body was highly incinerated, it is impossible to accurately determine the time of death, and he may have been killed after his disappearance. ”

"Two sets of fingerprints were collected from the deceased's rented house, and in addition to the deceased's fingerprints, the other set of fingerprints belonged to Zheng Jun, and there was no trace of a third person. The cause of death of the deceased was that the artery of the left hand was cut with a sharp weapon, and he died of excessive blood loss, the knife was shallow on the left and deep on the right, the murder weapon was a fruit knife held by the deceased's right hand, the right arm was on the right edge of the bathtub, and the fruit knife was on the ground directly below the right hand. Only the fingerprints of the deceased were on the handle of the fruit knife, and the alcohol content of the deceased's body was higher than normal, and he should have been alcoholic on the day of death. ”，

Officer Cao frowned, pinched his chin with his hand, and pondered the wording of Officer Zhang of the forensic team.

"What's the progress in the technical section?" Officer Cao raised his eyes and looked at Xiao Li of the Technology Department.

Xiao Li said: "I checked the WeChat chat records of the deceased before his death, QQ, and Weibo, of which Weibo was updated before 22:42 on May 8: I can't stay together in the bright light, and I'd rather die together." Love that is not accepted by the world can only be justified by death.

"Due to the limitation of Tencent's server storage space, we can only retrieve WeChat records within seven days, find the deceased's mobile phone in the rental house, and restore the WeChat chat records stored in the mobile phone through technical means, and store the WeChat records for more than a year, we are also screening from near and far, most of them are daily conversations with family members, the highest frequency is Zheng Jun, Wang Xiang, Jia Rupeng's dialogue, the deceased had an improper relationship with these three men before his death. There are also many men who send messages to the deceased, and the frequency is not high, a few times a week, or a half. Now WeChat is still investigating, I watched it all night yesterday, and I only read the record for half a year" Xiao Li is a little crying and laughing, and now there is a feeling of spying on other people's privacy. ”

After Xiao Li finished speaking, Officer Cao nodded thoughtfully, indeed, if you want to check WeChat, you have to get the data stored on your mobile phone, and there is too little information on Tencent's server. Zheng Jun, Lin Ling's previous investigation seems to be just the tip of the iceberg. Where did Zheng Jun's phone go?

Everyone saw that Team Cao didn't say a word, and whispered below:

"Maybe I killed Zheng Jun and committed suicide again."

"It's hard to say, maybe the adultery will be revealed, and both of them will be solved by which lover."

Everyone, you and I, actively discuss the facts of the case. At this time, Officer Cao's phone rang suddenly, and everyone was silent, looking at Officer Cao's uncertain expression when he answered the phone.

Officer Cao put down the phone and said, "Let's go, go to the warehouse on the outskirts of the city, there is a major discovery over there." ”
