Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

"Zhang Fenglu? Please tell me more about him." Wang Shuai was overjoyed and immediately asked. Manager Liu recalled, "Zhang Fenglu, 50 years old, about 175 centimeters tall, weighing over 60 kilograms, with black and white hair, basically matches the description of the deceased you gave. He worked for our company for 3 years, mainly responsible for night patrols in several residential areas around Jianshe Road. A week ago, he suddenly resigned, saying he was going back to his hometown, and we haven't been able to contact him since."

"What kind of work clothes did he wear before he resigned?" Wang Shuai asked anxiously. Manager Liu immediately asked a staff member to bring out a set of the company's security guard uniform: "Our company's uniform is a gray long-sleeved T-shirt and dark blue work pants, exactly the same as what the deceased in your photo was wearing! Moreover, he usually wore black cloth shoes, saying that they were comfortable and suitable for long patrols."

This information thrilled Wang Shuai; the deceased's identity seemed to be confirmed. However, he remained vigilant and continued to verify the details: "Was there anything unusual about Zhang Fenglu before he resigned? For example, was he depressed, had conflicts with others, or was he experiencing financial difficulties? What was his exact address? Did he have any relatives?"

Manager Liu thought for a moment and said, "Zhang Fenglu is rather introverted and doesn't talk much. He was acting strangely a few days before he resigned; he was always sighing, as if something was on his mind. When we asked him what was wrong, he wouldn't say. He rents a place to live, but I don't know the exact address, only that it's near the Jianshe Road community. He doesn't seem to have any relatives in the area and lives alone." Manager Liu then provided Zhang Fenglu's employment registration form, which included his ID number, contact number, and emergency contact information, but the emergency contact's phone was constantly unreachable.

Wang Shuai immediately instructed his team to check Zhang Fenglu's household registration and residence information based on the ID number on the employment registration form. At the same time, he asked Manager Liu to provide Zhang Fenglu's photo and work ID for further verification. Manager Liu found Zhang Fenglu's one-inch passport photo and work ID in the company's employee files. The photo showed Zhang Fenglu with black and white hair and a haggard face, perfectly matching the deceased's physical characteristics.

At 8 PM, the team member checking household registration information reported that Zhang Fenglu, male, 50 years old, was registered in a neighboring city's county, but his registered address in this city was Room 101, Unit 3, Building 5, Jianshe Road Community, which was near the crime scene. Wang Shuai immediately led the team to the address to verify. Upon arriving at Room 101, Unit 3, Building 5, the team found the door locked and received no answer when they knocked. Wang Shuai contacted the landlord, who arrived and opened the door.

The room was cluttered and dusty, indicating it had been uninhabited for some time. The team conducted a thorough search and found several sets of grey long-sleeved T-shirts and dark blue work pants identical to those worn by the deceased in the bedroom wardrobe, along with several pairs of black cloth shoes, all size 42, matching the shoe size found in the shoe prints at the scene. On the living room table, they found Zhang Fenglu's ID card, bank cards, and a mobile phone charger, but did not find the corresponding passbooks for the phone and bank cards.

"The discovery of these items further confirms that the deceased is Zhang Fenglu," Wang Shuai said. "We immediately collected trace evidence such as hair and fingerprints from the room and compared them with the deceased's DNA sample and fingerprints. At the same time, we checked Zhang Fenglu's bank statements to understand his financial situation." The team members quickly started their work, collecting multiple hair and fingerprint samples and sending them to the technical department for testing.

At 9 p.m., the technical department reported that the hair and fingerprint samples extracted from the room matched the deceased's DNA and fingerprints perfectly. Zhang Fenglu's bank statements showed that for the past three months, his account had only received a fixed monthly salary, with no large inflows or outflows, indicating a relatively ordinary economic situation and no huge debts or abnormal financial transactions.

At this point, the deceased was officially identified as Zhang Fenglu, a former security guard from Chengxin Security Service Co., Ltd. However, Wang Shuai did not feel relieved, as there were still no leads regarding the suspect. "Zhang Fenglu's unusual emotional state before resigning suggests he may have had a conflict with someone or encountered some trouble. We need to focus our investigation on his work situation and social relationships before his resignation, especially the businesses and residents in his patrol area, as well as his colleagues, to find out if he had any enemies," Wang Shuai adjusted the direction of the investigation again.

At 10 p.m., Wang Shuai led his team back to Chengxin Security Service Co., Ltd., and questioned several colleagues who had a good relationship with Zhang Fenglu. "Zhang Fenglu was usually very hardworking, but he was too introverted and not very sociable. A few days before he resigned, I saw him arguing fiercely with another security guard in our company, Li Wei, in the duty room. I didn't hear the specifics of what it was about," a colleague recalled.

"Where is Li Wei now? What's his relationship with Zhang Fenglu like?" Wang Shuai asked. Manager Liu replied, "Li Wei is off duty today and should be at home. His relationship with Zhang Fenglu is so-so; they often argue about the division of patrol areas." Wang Shuai immediately obtained Li Wei's address and contact number and arranged for a team member to go and verify.

At midnight, the team members who went to verify Li Wei's situation reported back: Li Wei, male, 45 years old, 178 cm tall, weighing 70 kg, was resting at home between 11 pm the night before the incident and 2 am yesterday. His wife and neighbors testified to this, and his alibi was established. Li Wei's shoe size was 44, which did not match the shoe size of the footprints collected at the scene. In addition, he usually wore sneakers, which did not match the leather shoe prints and rain boot prints collected at the scene. He was temporarily ruled out as a suspect.

Subsequently, the team visited several businesses and residents within Zhang Fenglu's patrol area. All stated that Zhang Fenglu was usually conscientious and responsible in his work, friendly, and had never been involved in any violent conflicts, nor did they discover any unusual social connections. As of 1:00 AM, the investigation into the suspect had still not made substantial progress.

At this time, the autopsies of Zhang Kai and Xiao Lin had been completed, and the autopsy reports were being finalized. Wang Shuai, carrying the confirmed identity of the deceased, went to the Criminal Investigation Division to report to Lu Chuan. After listening to the report, Lu Chuan affirmed the work of Wang Shuai's team: "Although we haven't found any clues about the suspect yet, confirming the identity of the deceased is an important step in solving the case, pointing the way for subsequent investigations. Zhang Fenglu is a security guard responsible for night patrols, and his area of ​​activity is fixed. The suspect is very likely within his patrol area, or someone related to his work and life."
