The forensic wife is very nice to me

"Xiao Cong, call expert Cao Fan from the forensics department. There are some mysteries that need his help to solve." Qiu Lan raised her eyebrows and spoke in a calm tone.

"Yes." Assistant Xiao Cong put down the things in his hands, walked to the table, and prepared to contact the forensics department.

But at the same moment, the phone rang.

It's Cao Fan's call.

"Hello, Expert Cao." Xiao Cong turned on the hands-free button and greeted politely.

"Hello, Xiao Cong, is Dr. Qiu here? We found something in the evidence collected at the scene yesterday. I think it should help Dr. Qiu's judgment." A deep voice came from the receiver of the phone.

When Qiu Lan, who was standing next to the planing table, heard this, she put down the equipment in her hand and strode to the phone.

"Expert Cao, I'm Qiu Lan. I was just about to call you. I wonder if the substance I asked you to test yesterday has any results?"

"I was just about to tell you that I found Bill's hydroxyacid at a concentration of two percent in a sample of gasoline in the barrel yesterday."

"And the white substance on the surface of the oil layer is the product of its esterification, Bill Hydroxy Acid Diester Celery."

"This substance has a high-strength thermal insulation effect."

Qiu Lan and Cao Fan said this sentence almost in unison.

"Doctor Qiu is really amazing. He can answer this question so quickly. If I didn't know that you are a forensic doctor, I would really think you are a genius in chemistry." Cao Fan praised him affirmatively.

To be able to skip the stage of being a forensic assistant at a young age and directly become an official forensic doctor of the police department's forensic department is already very remarkable.

In the previous two cases, Cao Fan saw Qiu Lan's excellent thinking ability and logical analysis ability, and he couldn't help admiring her.

"Expert Cao is overrated, and I have only read such books before. Forensic medicine, I need to know more about it." Qiu Lan responded to him modestly, and then turned her attention to the case.

"By the way, as far as I know, bier hydroxyacid diester celery is also very corrosive, and it also confirms why wounds that take three to five days to rot will rot within a few hours after death. It just appeared."

"Expert Cao, thank you very much." Qiu Lan frowned, suddenly enlightened.

After hanging up the phone, she lowered her eyes, thinking silently in her heart, and kept murmuring.

"Bill hydroxyacid diester celery, this substance has not yet been specifically calculated by international authoritative organizations or experts for its heat preservation effect. How can we judge the death time of the deceased?"

Xiao Cong, who was standing aside, frowned, thinking about this question together.

Suddenly, Qiu Lan's eyes flashed, and she thought of a method that had been used in scientific verification.

"Xiao Cong, the inspection of the corpse is almost finished, there is only some finishing work left, you don't need to worry about it for now, you go to the market here to find me a piece of pork liver and pork belly at least eight centimeters thick. "

"it is good."

Although Xiao Cong didn't know what she wanted these things for, but since she said so, there must be her intentions.

In the next half an hour, Qiu Lan made a record of the final inspection of the corpse, then sewed up the corpse, and then sent it back to the freezer for frozen preservation.

By the time she finished all this, Xiao Cong had bought everything back.

They found a transparent glass sink and added another two thousand milliliters of gasoline.

Finally, Qiu Lan found a heater and heated the liver to 38 degrees and the pork belly to 37 degrees.

These data are exactly the same as those of the human body.

"Doctor Qiu, what are you going to do?" Xiao Cong helped her with these things, but he was still puzzled, so he couldn't help asking.

"This is a reduction method. The composition of the pig liver is not much different from that of a human liver, and the pork belly represents the fat layer and muscle layer wrapped around the liver."

Qiu Lan picked up the pork belly, wrapped a circle around the pork liver, cut off the excess, and finally sewed it up.

"Look, although the appearance is quite different, is it the same as the structure of the human body?"

She pursed her red lips, and methodically added an appropriate amount of bier hydroxy acid diester celery, which just formed a solution with a concentration of [-]%.

"Xiao Cong, for the next time, you have to stay here and measure the temperature of the liver every 5 minutes until the temperature of the liver drops to about 32 degrees."

"I understand." Xiao Cong nodded, his admiration was beyond words.

He originally thought that the case this time was more complicated than the previous ones, and the work of determining the time of death was even more difficult, but Qiu Lan's small solution solved all the problems.

Qiu Lan gave a few simple instructions, then turned and walked into the laboratory.

While waiting, she made a small piece of tissue that had just been cut from the corpse into a slide and examined it carefully under a microscope.

There is indeed no green part.

Afterwards, she conducted a test with a chemical experimental agent, and it was confirmed that there was no copper oxide on it, which meant that the rusted copper wire Henry discovered yesterday was indeed not a murder weapon.

The experiment went on for more than two hours, and after Qiu Lan packed up all the experimental supplies, Xiao Cong also got the results.

This result was very surprising.

"Doctor Qiu." Xiao Cong excitedly walked up to Qiu Lan with a notebook, his eyes shimmering, "It is true that the deceased did not die an hour before the discovery."

"I measured the temperature of the liver. After three hours and 5 minutes, the liver temperature dropped to 32 degrees. This process lasted for 8 minutes."

"In other words, it took about three hours. According to the situation at that time, the deceased should have died three to four hours ago."

"The time we checked was five o'clock in the afternoon, that is to say, the time of death was between one o'clock and two o'clock in the afternoon, and the time when a fight occurred or was beaten was between eleven o'clock and twelve o'clock in the noon."

All things suddenly became clear and the mysteries were solved.

As for why beer hydroxyacid diester celery appeared in the gasoline in the oil drum, and how the corpse was put in, all these issues must be dealt with by the serious crime team.

However, Qiu Lan's identification results have given them a lot of help.

"Xiao Cong, send a copy of our autopsy report to Police Officer Xu, and tell him the time of death we judged, as soon as possible."

After dealing with the corpse, Qiu Lan changed into the surgical gown, lit the incense, lay down on the swivel chair and closed her eyes to rest for a while.

The wall clock on the wall was ticking, and she glanced up at the hands.

It's already one o'clock in the afternoon.

She hasn't had a sip of water or eaten since morning.

The gurgling sound of her stomach did not allow her to sit indifferently in the office any longer.

Qiu Lan stretched, put on her coat, and walked to the cafeteria.

But just as she got off the elevator and walked out of the elevator door, a black shadow passed by, and someone patted her shoulder lightly.
