Chapter 6 Their Greed (IV) Inference
After a whole night of waiting, everyone was exhausted and finally received two appraisal reports.
However, the results were disappointing, with both reports not matching the deceased.
Han Jianye immediately went to the Visual Reconnaissance Department to look for Su Wan, while Ye Bai focused his attention on the sheet wrapping the body.
Ye Bai noticed that the bed sheet was a thick coarse cloth suitable for all seasons, printed with a purple leaf pattern. It measured 240 cm by 230 cm, suitable for a 1.8-meter-wide bed.
He inferred that the deceased's family might be of average economic condition.
Then, he turned to Liao Wei and put forward his own opinion: "There is no blood on the bed sheet. This may be because the blood disappeared after being soaked in water for a long time, or the deceased was killed in another location, and the murderer then wrapped and tied the body with a bed sheet and dumped it."
Liao Wei nodded in agreement and added his own speculation: "Like you said, I think the bathroom is likely to be the first crime scene. The victim may have been killed while undressing to take a bath, or just took off his clothes and was only wearing underwear, or was killed while changing clothes by the bed."
Ye Bai looked at the photo carefully and found that the underwear worn by the deceased should have been bright red before it faded.
He suddenly had a bold guess: "The deceased was wearing red boxer briefs when he was alive. Is it possible that this year is his zodiac year?"
Liao Wei believes this speculation is possible, and further analyzed: "This year is the Year of the Pig in the Chinese Zodiac. If calculated according to the birth year, the deceased should be born between 1983 and 2019, and his actual age is 36, and his virtual age is 37. But I think wearing red underwear is not necessarily for the birth year. It depends on personal choice. I usually wear red myself."
Ye Bai raised the issue again: "Sister Shaozhen only said that there is a two-year discrepancy, which is the result of various factors. So the deceased could be 38 or 42 years old. I just guessed that this year might be the deceased's zodiac year, and this possibility cannot be ruled out."
After saying that, Ye Bai turned around and went to find Mai Shaozhen to confirm the age of the deceased.
Liao Wei followed closely and asked, "Where are you going?"
"I'm going to find Sister Shaozhen to confirm the age of the deceased again." Ye Bai replied.
At this time, Mai Shaozhen was concentrating on examining the head in her hand. She was a little surprised by the arrival of Ye Bai and Liao Wei.
After understanding their purpose, she pointed to the teeth of the skull and began to explain: "In fact, in addition to judging the age of the deceased by the pubic symphysis, we can also infer the approximate age of the deceased by observing the degree of wear of the teeth.
We usually classify tooth wear into nine levels. The tooth wear level of this deceased person belongs to the fourth level, and the corresponding average age is about 38 years old. This is not much different from the 40-year-old age of the deceased that we previously inferred from the pubic symphysis, with an error of only two years. ”
Ye Bai asked, "So, is it possible that the deceased was really 38 years old?"
Mai Shaozhen nodded in agreement: "Based on the current inference, this is indeed possible."
"Is it possible that the deceased was younger?"
"In comparison, the error in inferring age through teeth is larger and is easily affected by external factors, while the judgment of the pubic symphysis is more accurate."
Ye Bai nodded in understanding: "Okay, I understand."
Just as Ye Bai was about to leave, Mai Shaozhen called him: "Xiaobai, when are you free? I'll take you around the city."
Ye Bai wanted to refuse because he was not interested in shopping, but then he thought that as a local, Mai Shaozhen might be able to help keep an eye on the houses near the police station.
So he changed his mind.
On the way back, Liao Wei walked side by side with Ye Bai. He asked in surprise: "Are you really living in the same dormitory with Captain Han?"
Ye Bai nodded expressionlessly.
Liao Wei couldn't help but admire: "Great, you are really courageous."
He thought that his new colleague Ye Bai might not understand Captain Han's character, but he couldn't say it out loud for fear of scaring Ye Bai away.
At the same time, Han Jianye was also helping to watch surveillance videos in the visual detection department.
Since there are few surveillance cameras on the streets near the river and the surveillance video was taken more than a month ago, the search became extremely difficult.
Fortunately, the surveillance video at the intersection has a large storage capacity and can save 1 to 3 months of footage. Videos older than three months will be automatically overwritten, so they still have a chance.
Han Jianye analyzed: "The cement road along the river cannot accommodate large vehicles, so we mainly check small vehicles, such as cars, tricycles, and vans. Any suspicious vehicle that stays near the river for more than three minutes should be included in the list of key suspects."
He speculated that the murderer might be from outside the area and that the crime was committed by multiple people. They were unfamiliar with the local routes, so they might have been driving slowly while looking for a suitable place to dump the body.
Su Wan looked up and put some eye drops in his eye. He watched the surveillance video of the whole night, frame by frame, not daring to miss a single second, for fear of missing important details and having to rewind and watch it again. His eyes became red from staying up all night.
