Chapter 1158 Deliveryman Sun Biao
As the meeting adjourned, the morning light filled the conference room, casting long shadows that crisscrossed across the files. While tidying up the autopsy report, Zhang Lin suddenly said to Li Ming, "The wine found in the deceased's stomach was 'Château Lafite Rothschild,' a 2010 vintage. Only five restaurants in the city sold it. This can pinpoint his activity range." Li Ming nodded, his grip on the enamel mug resolute: "Even if he sprang from a rock, we'll find his 'origin'."
The motion-activated lights in the corridor flickered on and off with the sound of footsteps. The marks of the argument on the whiteboard had not yet been erased. The words circled in red, such as "acquaintance crime," "military and police background," and "high-end consumption," gleamed coldly in the sunlight, as if pinning down several key coordinates for this shrouded case.
When Xiao Zhou's police car stopped at the glass door of "Kangtai Dental Clinic," the midday sun was shining through the window, casting glaring spots on the "Painless Treatment" sign. He clutched the ceramic filler composition report provided by the forensic doctor, his fingertips repeatedly rubbing the words "95% zirconium oxide content"—of the three clinics in the city that used this material, the first two had been investigated without success, and this small shop on the east side of Beishan Park was the last hope.
The clinic's disinfectant scent mingled with the sweet aroma of mints. A nurse in a white coat was wiping the dental chair with alcohol swabs, the metal instruments gleaming coldly on their trays. "We're from the criminal investigation team," Xiao Zhou said, flashing his badge as his gaze swept over the medical certificates on the wall. "We want to check male patients aged 35-40 who have used zirconia ceramic fillings since 2022, with a scar on their right eyebrow." The nurse paused, then turned and pulled a thick registration book from the filing cabinet; the edges of the pages were curled and wavy from frequent flipping.
“Zirconium oxide filling is an imported material, expensive, and not many people use it,” her fingernail stopped on the name “Sun Biao.” The man in the registration photo had a shallow scar on his right eyebrow and a faint black mole behind his left ear. “He visited on March 12, 2023, for root canal treatment and filling of his lower left second molar. At the time, he said he was a courier and had fallen off his motorcycle while delivering goods, injuring his eyebrow.” Xiao Zhou’s heart skipped a beat. The shape of the scar in the photo matched the skull reconstruction perfectly, and the location and size of the black mole were exactly the same.
“The contact number he left is this mobile number,” the nurse pointed to the number in the registration book. Xiao Zhou immediately asked Xiao Zhao to dial the number. A mechanical female voice came from the receiver: “The number you dialed is out of service.” He opened Sun Biao’s medical record. His past medical history stated “no special diseases,” which perfectly matched the forensic report that stated “no organic lesions.” The home address was filled in as “Building 3, Room 501, Beishan Community,” which is only 800 meters away from the park, consistent with the speculation that he was “familiar with the terrain.”
"When was his last check-up?" Xiao Zhou's fingertip traced the date "January 2024." The nurse suddenly remembered something: "He came to get his crowns replaced before May Day this year, saying he was worried about dental problems from long-distance travel. He also complained that someone had been following him recently, and that the packages on his delivery truck had been tampered with." Xiao Zhao, who was taking notes, asked, "Following? Who exactly?" The nurse shook her head: "He didn't go into details, just said it might be competition from other professionals, and told us to keep an eye out for suspicious individuals."
When they arrived at Beishan Residential Area, a yellowed electricity bill was pasted on the security door of apartment 501 in building 3, dated May 10th. When the property manager opened the door with the spare key, the rust clicked in the lock: "This family is quite strange. Sun Biao lives alone, usually leaves early and returns late, riding a blue motorcycle, always with a black briefcase in the back." Xiao Zhou's gaze fell on the coffee table in the living room; the leftover steak packaging was still in the trash can, the label indicating it was takeout from "Black Knight Steakhouse"—a perfect match for the contents of his stomach.
Three grey jackets hung in the bedroom closet, their fabric labels indicating 30% wool, matching the fibers found at the scene. The bottom jacket had a hole in the left chest area, and the missing button perfectly matched a black resin button found near the park fountain. "He tore it when he crashed his bike," the property manager added. "He said he was going to get it mended last month, but he hasn't had time yet." In the bedside table drawer, a pack of Zhonghua cigarettes pressed down on a business card: "Sun Biao, Global Financial Investment Advisor," with the words "See you at the park at 10 PM on May 14th" written in pen on the back.
Contacting Sun Biao's family proved more difficult than anticipated. The household registration system showed his parents had passed away early, and his only relative was his cousin, Li Qiang, who lived in a neighboring city. When the call connected, Li Qiang's voice was still groggy from just waking up: "Biaozi? He hasn't contacted me since May Day. He said he was working on a big deal, and if it went well, he could get a car..." When Xiao Zhou described Sun Biao's features, the other party suddenly fell silent, then choked up after a long pause: "The scar on his right eyebrow is from when he fell while climbing a tree as a child, and the mole behind his left ear has hair growing on it... You found him?"
DNA matching requires samples from immediate family members, so Li Qiang rushed to the Criminal Investigation Detachment that afternoon, his fingers trembling so much he could barely hold the cotton swab when his blood was drawn. "He's always been very competitive," Li Qiang said, tears dripping onto the lab report. "Delivering packages was just a temporary thing; he always said he wanted to work in finance, he even partnered with someone to speculate in stocks, and last year he said he was scammed out of hundreds of thousands of yuan..." Xiao Zhou suddenly seized on the key point: "Scammed? Does he know who the other party is?" Li Qiang shook his head: "He wouldn't say, just said, 'They're people in the underworld, I can't afford to mess with them,' but last month he said he was going to seek justice and told me not to worry."
The technical department's comparison results came out early the next morning. Li Qiang's DNA matched the deceased's genotype perfectly at 16 STR loci, with a paternity probability greater than 99.99%. "The deceased is confirmed to be Sun Biao, male, 38 years old," Xiao Zhou wrote the conclusion on the whiteboard, the red marker marks penetrating the back of the paper. "His apparent occupation was a courier, but he was actually involved in financial investment. In 2023, he suffered losses from stock trading and had a debt dispute with others. On the evening of May 14, he arranged to meet 'people in the underworld' at Beishan Park."
Xiao Zhao suddenly found a USB drive in the storage compartment of Sun Biao's motorcycle. The chat history in the encrypted folder showed that he had frequent contact with someone nicknamed "Scarface Liu". The last message was at 9:50 PM on May 14: "Have you prepared the money? Don't try anything funny." The other party replied: "See you at the usual place, bring the contract." Xiao Zhao retrieved "Scarface Liu's" phone number. The owner's information showed that he was Liu Zhiqiang, who had multiple prior convictions for extortion, was 178cm tall, and rode a black motorcycle. His footprints at the scene matched the description perfectly.
“Sun Biao’s identity as a courier was a facade,” Xiao Zhou stared at the word “contract” in the chat history. “He may have used his delivery business to engage in illegal financial activities, which Liu Zhiqiang seized upon to blackmail him. The meeting on May 14 was to pay money to avoid trouble, but it resulted in a dispute and he was killed.”
