The female forensic doctor is coming to the bowl

Chapter 55

Qu Mo went directly from the crematorium to the rental house, and saw Zeng Yirou was also there.

"It's been half a month since I started the haircut, and many traces have disappeared. All the places in the house have been carefully washed, and we asked Dr. Zeng to do a blood test," Lu Li explained.

Qu Mo nodded, leaned close to Yirou to have a look.I saw her sprinkle a spray-like thing on the wall, and after a while, a blue-green fluorescent substance appeared.

"This is the luminol reagent, which is mainly used for blood testing in modern criminal investigations. It has long been used in criminal investigations abroad, but it is still a preliminary attempt in our city." She explained to Qu Mo, "Team Qu should have seen it abroad. .”

"Well. Luminol reacts with hemoglobin, showing blue-green fluorescence. This detection method is extremely sensitive, and can detect blood with only one part in a million. Moreover, the blood that has been treated with luminol contains The genetic material DNA has not been destroyed, and it can be extracted for identification." Qu Mo did not expect the domestic technology to develop so fast, and he was gratified in his words.

Yirou expanded the scope of spraying reagents, and soon made a gratifying discovery.

"Doctor Zeng, what do you think?" Qu Mo asked the blood-spattered walls and floors.

While taking a blood sample, Yirou replied: "The blood splatter is obvious, and it was caused by repeated blows to the head of the deceased with a blunt instrument."

"Oh? Why is it a blunt weapon attack?" Lu Li asked suspiciously.

There is no dead body here, no murder weapon, how can you make such a judgment based on blood stains alone?
"The arterial vessel ruptures, and due to the pressure generated by the contraction of the heart and the retraction elasticity of the arterial vessel wall, the blood spurts out, forming blood splashes in the shape of an exclamation mark on nearby objects, with their tips pointing towards the spraying direction." He explained softly, "If you are injured and bleed from repeated blows with a blunt instrument, blood splatters can also form, but the size and shape are different, and the distribution is scattered."

Qu Mo heard a little more appreciation in her eyes. This girl who majored in forensics can study forensic evidence to such an extent, which shows that she has worked hard on weekdays.

"The provincial bureau will soon send a group of forensic personnel to our bureau, and then Dr. Zeng won't have to be so busy. But it's a pity that Dr. Zeng is so proficient in forensic evidence." Lu Li nodded when he heard Yirou's explanation.

"I'm just self-taught, and I don't pay attention to professional talents. I can only use a few of the equipment in the bureau. It's really wasted. Yesterday, I saw them tidy up the second floor of the office building opposite. , probably for the newly established forensic department." Yirou packed the blood sample, "Go back for testing and analysis, and it will take three days at the fastest to get the results. But—" She paused, looking at Qu Mo .

"According to the large amount of blood found at the scene, it is estimated that it is enough to cause the death of an adult. But-is this person really Li Jiantian? Isn't he a murderer and a fugitive?"

After hearing this, Lu Li looked at Qu Mo, which was exactly the doubt in his heart.Received Qu Mo's call, he was like Zhang Er's monk who couldn't figure it out.

"Not only did he die, but he also turned into ashes!"

Qu Mo's words stunned everyone, and Meng Zhe suddenly realized, "The Li Minghao that Cai Yong said was Li Jiantian? Then who killed Cai Yong?"

The case seemed to be getting more and more complicated and confusing, which made everyone confused.Back at the police station, Qu Mo immediately took everyone to a meeting to sort out the case again.

"Team Qu, please tell everyone, what's going on? Now everyone is confused, how are you going to solve the case?" Meng Zhe couldn't wait to ask.

"It was your unintentional sentence that reminded me."

"Me?" Meng Zhe looked at Qu Mo with a blank face, "What did I say?"

"Li Jiantian has been missing for half a month. I can't see anyone alive or dead. At that time, I felt very strange. Your unintentional 'turned into ashes' made me suddenly understand. I think of your career as Cai Yong, and I think there must be something tricky in it. , I want to go to his company to check again.

Unexpectedly, I happened to meet Xiaofang and Wang Debiao quarreling, and the date on the invoice was exactly half a month ago, which made my doubts more and more serious.When I arrived at the crematorium and saw the watch on Wang Dehua's wrist, I was even more sure that Li Minghao was Li Jiantian. "

"Watch? Although that watch is valuable, you can't be sure it's Li Jiantian's?" Meng Zhe asked suspiciously.

Qu Mo took out a newspaper from a month ago, opened the financial section, and there was a photo of Li Jiantian on it.On his wrist, he wore that watch, exactly the same.

"Patek Philippe, a top luxury brand. This is a limited edition of this brand, and only [-] pieces have been released in the world. Obviously, Li Jiantian likes this watch very much and always carries it with him. Look!" Qu Mo said again Take out a few old newspapers, which have an exclusive interview with Li Jiantian.The clothes are different, but he always wears the watch.

Everyone looked at the newspaper, and immediately fell in admiration for Qu Mo.Ordinary people read newspapers just to pass the boring time, but he did not expect to find clues to solve the case from them.Even a small inconspicuous detail, he can still find it still fresh in his memory. His observation and memory skills are really impressive!
"Cai Yong is the most suspected of Li Jiantian's death, so who killed Cai Yong?" Meng Zhe's question made everyone fall into deep thought.

At the scene of Cai Yong's death, the murder weapon was left with Li Jiantian's fingerprints on it.Moreover, the murderer obviously used a key to enter the house, or Cai Yong opened the door, and Cai Yong entered the bedroom with his back facing the murderer, without any precautions. All this shows that an acquaintance committed the crime.Then, besides Li Jiantian, who else is so familiar with Cai Yong?
Since Li Jiantian died half a month ago, who made the call that Liu Wanru received ten days ago?

"Liu Wanru deliberately concealed the fact that he knew Cai Yong, and said that he received a call from Li Jiantian asking for a divorce. It is very likely that the key to Cai Yong's house was given to Li Jiantian, and the person who can get the key from Li Jiantian and get his fingerprints ..." Lu Li paused at this point, his eyes darkened, "Only Liu Wanru!"

"But the night Cai Yong was killed, she had evidence of her alibi." Wang Renfu frowned, watching with the witness's testimony in his hand.

"But I think the testimony of the witness just shows that she has a serious suspicion." Qu Mo asked Wang Renfu to read the testimony to everyone.
