The Forensic Doctor Better Than a Detective-Chapter 150 - 134: Return to the Scene of Death

"However, if the fingerprints on the bottle match those on the knife handle, then Zhang Biao’s death appears to be quite unusual."

For a moment, Zhang Yean did not react.

"Mr. Li, what do you mean?"

Li Jian said in a deep voice, "If Zhang Biao is the murderer, then his death is not simple and might not be accidental."

"Not accidental?"

Li Jian continued to analyze, "It’s also possible it’s a suicide out of guilt."

"But regardless of the possibility, we must clarify it."

Li Jian and Zhang Yean seemed very optimistic, as if they were confident about the bloodstains on the glass bottle.

However.

Compared to their optimism, Jiang An seemed preoccupied.

In Jiang An’s view, although there was a bottle of wine and a pack of snacks in the cabinet, it felt too clean.

The cabinet of an adult bachelor, surprisingly so tidy, without even a few miscellaneous small items.

Jiang An found it somewhat unusual and was very puzzled internally.

Seeing Jiang An still dazed, Li Jian walked over and patted him on the shoulder.

"Jiang An, maybe you were thinking too much just now."

"For a bachelor, it’s normal not to be good at tidying up like girls. It’s normal to have many clothes on the bed."

"Moreover, there’s an air conditioner installed in this room. Maybe the deceased liked to turn on the air con in summer and sleep under a thick blanket."

After a slight pause, Li Jian said, "Let’s go! Let’s quickly take the wine bottle back to the lab, get the physical evidence earlier."

Jiang An looked at Li Jian, said nothing, and followed him out of the security room.

minutes later, the three returned to the criminal investigation team.

As soon as they entered the lab, Zhang Yean immediately got to work.

She first placed the liquor bottle from Zhang Biao’s cabinet in the fingerprint visualization chamber to display the fingerprints on the bottle.

Li Jian accompanied her the entire time.

minutes later.

Zhang Yean opened the glass cabinet, took out the glass bottle, and it was evident that there were many fingerprint marks on the side of the liquor bottle.

Zhang Yean said, "Mr. Li, from the fingerprint marks on this glass bottle, it fits very well with the behavior of picking up the bottle with the right hand and pouring wine.

Li Jian nodded; he extended his right hand, making a wine-pouring gesture.

Then he asked, "Can the time when the fingerprints were formed on the bottle be determined?"

Zhang Yean shook her head, "Mr. Li, it’s impossible to compare the time the fingerprints were formed."

"However, based on my personal experience, from the visualization results just now, I think the fingerprints weren’t formed long ago."

Li Jian looked at the visualization chamber, somewhat puzzled, "Is there a particular reason for this?"

"Mr. Li, because the shorter the time the fingerprints are formed, the clearer the fingerprint visualization."

"The fingerprints on this glass liquor bottle look very clear."

Next, Li Jian turned to pick up the red liquor box and found the packaging date at the sealing.

"This wine has been sealed for 9 months."

Zhang Yean nodded, "Since it’s been so long, the fingerprints on this glass bottle could hardly have been formed before the sealing."

Li Jian nodded, saying, "Zhang Yean, immediately compare these fingerprints with the ones on the bottle."

Immediately, Zhang Yean turned and left for the evidence storage room.

minutes later, she returned wearing gloves with the dagger in hand.

Then Zhang Yean placed the dagger and the liquor bottle onto the lab table and bent over to carefully observe.

After a short while, Zhang Yean shook her head.

"Mr. Li, the patterns of these two fingerprints do not match!"

"Are you sure?"

"Absolutely sure!"

After thinking for a while, Li Jian said, "If the blood test on the bottle is entirely consistent with the genetic analysis on the bones, it can rule out Zhang Biao as a suspect."

Zhang Yean nodded, saying, "Mr. Li, I’ll immediately compare it with other fingerprints collected at the site." 𝘧𝓇ℯ𝑒𝓌𝑒𝑏𝓃𝘰𝘷𝘦𝘭.𝒸ℴ𝓂

"Good! Thanks for your hard work!"

Meanwhile.

Chen He was leading another criminal investigation officer to continue the on-site inquiries.

There’s only one road from the restaurant back to the construction site; it’s not far, just a 30-minute walk.

The two of them visited all the shop owners along the way and collected each individual’s fingerprints.

During the investigation, the fellow officer said, "Mr. Chen, do you think there’s a possibility that Liu Jun was secretly killed by an enemy?"

Chen He turned and glanced at him, saying, "Killed by an enemy? Have you been watching too many movies?"

"Even if he was killed by an enemy, it shouldn’t happen at the construction site."

"Besides, not just anyone can enter a construction site."

"Mr. Chen, while the main entrance of this construction site is strict, other areas of the fence can be accessed."

"From a spatial perspective, the possibility you mentioned indeed exists."

"However, our understanding of Liu Jun’s personal status shows he was somewhat frivolous with men and women but had no bad habits."

"No criminal record in voting or fighting."

Just as he finished speaking, the fellow officer said, "However, Liu Jun did have an STD; from that point, I don’t think he was a good person."

Chen He turned his head and said, "Regarding his STD, Liu Jun himself hadn’t figured out how he got infected."

"When he was being treated at the hospital, he repeatedly asked the attending doctor why he caught the disease."

"Mr. Chen, could it be possible he wasn’t honest with the doctor? After all, such a disease is quite shameful."

Chen He said, "If it was the first time he saw the doctor and was embarrassed, claiming he didn’t know how he got the disease might be understandable."

"However, during the subsequent treatments, there was no need for him to keep harping on that question, asking it every time he visited the doctor."
