Li Fan went out, Zhang Han lowered his head again, and looked at the paper on the desktop.

This time, it is rare to see the photo of Levan's father again.

Seeing this, Zhang Han's heart suddenly moved, if there were ghosts poisoning in the Public Security Bureau, the person who poisoned him this time was very likely to be the same person who poisoned Li Fan's father back then.

In this case, this person's age should not be small......

Zhang Han immediately took out his mobile phone and dialed Li Fan's phone number.

Soon, there was a "click", the door opened, and Li Fan walked in from the outside.

"What's the matter?" Levan asked.

"Which of the three people who are cooking is older?" Zhang Han said.

"It's an old fritter." Levan said.

"Old fritters...... Which ......?" asked Zhang Han.

"It's Cui Bin who delivered lunch. What's wrong? Levan said.

"I think he's the most suspicious." Zhang Han said.

"He ......," said Li Fan with a look of disbelief, "is it impossible...... Although the old fritters are a little slippery and lazy, they are also the reason why they are about to retire, and they are still very good......"

Zhang Han then asked, "Then who do you think is the most suspicious of these three people?" ”

"This ......" Levandon was dumbfounded, as if it was any one, and he was not very suspicious......

But Levin said: "I think it should be young and easy to be bought...... Su Donghua just graduated less than two years ago...... Personality looks frizzy...... Some people in the action team said that he was very lazy...... Being able to deliver food this time is obviously not in line with his style...... So I think he's suspicious...... Maximum ......"

"If your father was also poisoned...... Could the person who was poisoned back then be the same person as the person who poisoned today......" Zhang Han said.

"This ...... This ...... "Levandon was stunned.

Who said no, if it's the same person, the person who is the most suspicious must be the old fritter.

The other two are not up to the mark in terms of age. At the time of my father's death, there were two other people, one was estimated to be still in high school, and the other was about the same age as himself.

"I think let's start with the older ones." Zhang Han said.

"Okay, I'll go find the old fritter now." After Li Fan finished speaking, he turned and walked out of the room.

Zhang Han waited in the room, and after a while, Li Fan came in from outside.

"The body was returned." Levan said.

"Okay, let's take a look at the corpse again." Zhang Han said.

He and Levan walked out of the office and into the autopsy office.

The body was wrapped in a bag, and the coroner was there with no one else.

Levan was tired of the coroner opening the bag, and the body was not wearing anything, and the abdomen had been dissected.

The coroner stood aside and said, "Madam, Dr. Zhang, I have completed the preliminary autopsy and found no problems. Now you need to have a deep examination of gastric juice, so please use your own toilet. ”

"I'm in trouble." Levan said.

The coroner nodded, turned to the side, sat down at the test table, and got busy.

Li Fan looked at Zhang Han and said, "What are you going to do?" ”

"I'm just doing an experiment, I'm not sure." Zhang Han said.

He then reached into his pocket, pretending to pull a silver needle out of his pocket. He pierced the silver needle directly into the corpse's Tianchi acupoint.

Tianchi acupoint is an acupuncture point on the hand syncope yin pericardial meridian, and Zhang Han also gave Quting acupuncture to the hand syncope yin pericardial meridian before. However, Zhang Han does not have acupuncture as an acupuncture point, which is really because it is not very convenient.

The Tianchi point is in the gap between the fourth ribs, an inch outside the head of the road. Between men and women, acupuncture is really not suitable.

This acupuncture point is called Tianchi acupoint, the reason for this name, is because the acupoint is located on the outside of the roadhead, and the road head is the high terrain on the surface of the human body, and the acupoint is also located at the high terrain, that is, the heavens. The substance in the acupoint is the high-temperature water vapor from the pericardium through the acupoint, and the heat dissipation and cold drop to the ground after the acupoint is the water, and the qi and blood of the acupoint are both at a high level and the water through the water, so it is called Tianchi.

Li Fan saw Zhang Han acupuncture on the corpse next to him, he was stunned for a moment, and then realized that Zhang Han should have used a silver needle to test the poison. On TV, it's often like this.

After a minute, Zhang Han pulled out the silver needle, but the silver needle was still in its true color, and it was not black at all.

Seeing this, Li Fan couldn't help but shake his head secretly, it seemed that he hadn't found it.

Zhang Han was also a little disappointed, originally thinking that if the toxins in Zhu San's body could not be completely discharged and were not in the gastric juice, it was very likely to remain here in the Yin Pericardium of the Hand. And what can be used as storage is basically the Tianchi Acupoint.

Now there is no ...... found in the Tianchi Cave

Hey? That's not right......

Zhang Han immediately realized that the poison that the silver needle could detect was generally containing sulfide. If there is no sulfide in it, it is undetectable.

This drug, which can cause a heart attack, does not necessarily contain sulfide, so the silver needle is obviously useless. Modern technology is required for laboratory testing.

So, Zhang Han looked at the coroner over there and said, "Coroner." ”

"What's the matter?" The coroner paused and asked.

"Can you please help me test this silver needle?" Zhang Han said politely.

"Bring it." The coroner said.

Zhang Han walked over and handed the silver needle to the coroner.

The coroner didn't take it by hand, but just asked Zhang Han to put the silver needle into the vessel next to him, and then poured in some liquid. He smiled and said, "I really didn't expect that I would be fortunate to help Dr. Zhang do the test." ”

"You're welcome, my medical skills are still not as good as modern technology. I don't know, how long will it take? Zhang Han said politely.

"About half an hour." The coroner said.

"I'm in trouble." Zhang Han said.

He walked back to Li Fan's side, and it just so happened that at this moment, Li Fan's mobile phone rang.

Li Fan took out his mobile phone and answered, and said, "Hey, Sister Chen?" …… Good, good...... I'll go over ...... now."

After hanging up the phone, Li Fan said goodbye to the coroner and beckoned Zhang Han to come out.

When he arrived in the corridor, Li Fan whispered: "I asked people to retrieve the video of the meal delivery, and I didn't find anything unusual about those three people. ”

"Didn't find it...... By the way, what about Cui Bin? Zhang Han asked.

Li Fan said: "The person has already left work, I just called him, saying that there is something in the team, let him come for a trip." Su Donghua and Ma Guoning should both be on duty in the team, but in order not to startle the snake and not to wronged people, I went to the monitoring room and asked people to check the video of the meal delivery in the morning, noon and evening. The people in the monitoring room didn't see anything abnormal, so let's take a look. ”

From the words, Zhang Han could still hear that Li Fan still didn't seem to want to believe that the old fritters were poisoned.

Zhang Han hesitated for a moment and said, "Do you know Cui Bin's home?" ”

"Of course I know, I've been there before." Levan said.

"His house is not far from the sheriff's office, how long does it take to get there?" Zhang Han asked.

"It's not too far, about 15 minutes by car." Levan replied.

"How long has it been now, why haven't you come yet?" Zhang Han asked again.
