Speaking of this, Lin Jiangbei glanced at the twelve people in the secret torture department with his eyes, and said, "Everyone, in order to prevent the poisoning suspect from secretly wiping off the oleander leaf powder on his hands, now please all stretch out your hands flat." I am not allowed to take it back until my inspection is over. ”

"Yes, yes, you guys stretch out your hands!" Du Chenghu waved his hand and ordered loudly, for fear that if his order was slow, the poisoned Wang Balamb would secretly wipe off the oleander leaf powder on his hand.

Since Du Chenghu spoke, whether they wanted to or not, none of the twelve members, including Chen Haitao, dared to slack off, and hurriedly stretched out their hands flat, for fear that they would stretch out slowly and be regarded as a poisoning suspect by the stationmaster.

Seeing that the twelve people stretched out their hands, Du Chenghu turned his head again, patted his thighs excitedly, and said to Lin Jiangbei: "You are really amazing!" Jiangbei, I can't complain that Professor Mao Xian said that you alone can promote the level of forensic medicine in the Republic of China for 20 years! If I were to look into this matter, I wouldn't have a clue at all. But for you, it was effortless, and it was easy to come up with such an ingenious solution! Hurry up and get started! ”

Speaking of this, Du Chenghu's face changed, he turned around and glanced at the twelve members of the torture department with a gloomy gaze, and said through gritted teeth: "Lao Tzu wants to take a look, which Wang Balamb dares to eat inside and out, is it really impossible to set up the family law of our intelligence department?" ”

"Okay, students will start right away!" Lin Jiangbei said to Du Chenghu, "However, Chief Inspector, the students have to state one thing first, that is, this method can only screen people outside the torture team. It is difficult to identify the four members of the torture team. ”

Speaking of this, he pointed at Gu Siqiang with his hand and explained: "Needless to say, Team Leader Gu, just now Secretary Chen asked him to go outside and get oleander leaves, and there will definitely be oleander leaf powder left on his hands." ”

Then he pointed to the other three members of the torture team, including Xu Zhiji, with his hand, "As for the three of them, their hands were stained with chili water during the torture, and the chili water contained cardiac toxins in oleander leaves, so the samples on their fingers would definitely react with the gallnut solution and appear pale green." ”

"But," Lin Jiangbei changed his words again, and said, "This method can help us identify whether the other eight people have oleander leaf powder on their hands." When the students questioned them just now, they all indicated that they had never touched oleander leaves, so if the sample taken from someone's finger showed a light green, then it meant that he was the poisoning suspect we were looking for. If there is no abnormal reaction in the samples collected, then it means that the suspicion of poisoning these eight people can be ruled out, and the poisoning suspect must be among the four members of the torture team. We just need to do a further screening among the four members of the torture team! ”

"I don't think there's a problem with this method at all!" Zhou Fengshan nodded heavily on the side and said, "Jiangbei, you can start now!" ”

In his opinion, even if the worst result occurs, it is a great success to narrow down the scope of poisoning suspects to four! I believe that Du Chenghu will also be satisfied with this result, after all, the workload of screening only the members of the four torture teams is much smaller, and it is relatively simpler, and more importantly, this can at least ensure the normal operation of the secret torture department, and will not paralyze the entire secret torture department because all the members are implicated.

"Principal Zhou, students start here!" Lin Jiangbei answered, walked to the water pipe in the stove room, unscrewed the water pipe, and put his hand under the water pipe to rinse.

While rinsing, he also explained to Zhou Fengshan and Du Chenghu, "Because the students' hands touched the oleander leaves just now, they should be rinsed first to avoid contaminating their samples when collecting samples from their fingers!" ”

Zhou Fengshan and Du Chenghu nodded and praised Lin Jiangbei's meticulous and serious work spirit. It seems that the professional forensic education is really different, at least the two of them did not consider the question of whether the oleander powder on Lin Jiangbei's fingers will cause contamination to the sample.

"That's right," Lin Jiangbei turned his head to Ye Luping and said, "Brother Luping, I have to trouble you to go to the pharmacy of the hospital to buy a bottle of gallnut solution and come back." You don't have to run too far, the 33 Hospital at the intersection of Nanshan Road and Liuying Road should have gallnut solution for sale. ”

Sansan Hospital was built by Qiu Jisheng, a famous doctor in Shaoxing, which was one of the few hospitals integrating traditional Chinese and Western medicine at that time, and traditional Chinese medicine agents like gallnut solution were one of the standing medicines.

"Okay, I'll go!" Ye Luping responded, turned around and ran out.

Lin Jiangbei had already rinsed his hands at this time, he shook off the water droplets on his hands, pinched out a handkerchief from his pocket with his fingers, wiped his hands clean, and took out a pair of white gloves from the infirmary and put them on carefully, and then said to Du Chenghu: "Inspector General, I have to trouble you to temporarily act as a student's assistant!" Help me carry the tray. ”

"No problem!" Du Chenghu took a step forward, picked up the tray with both hands, and honestly followed behind Lin Jiangbei as an assistant.

Lin Jiangbei was the first to walk up to Chen Haitao, smiled at him, and said, "Secretary Chen, I'm sorry, I'm offended!" ”

"It's okay! Work needs! Chen Haitao smiled generously and stretched out his hands cooperatively. He didn't have any opinion on Lin Jiangbei in his heart, because for him, this was also the best way to clear his suspicions!

Lin Jiangbei first took out a cleaned ampoule, added one-third of distilled water to it, and then took out a clean cotton swab, dipped it in the ampoule, and began to wipe it on Chen Haitao's fingers. Every time he wiped one of Chen Haitao's fingers, he would put a cotton swab into the ampoule and soak it for ten seconds, and then wipe Chen Haitao's next finger.

Three minutes later, Lin Jiangbei wiped Chen Haitao's last finger, soaked the cotton swab in the ampoule, and then took a pen to mark Chen Haitao's name on the ampoule, and then said: "Okay, Secretary Chen, your hand can be put down!" ”

Chen Haitao let out a long breath and put his hands down.

Lin Jiangbei walked up to the next person again, glanced up at him, and asked, "Name?" ”

"Zhong San is fat." The man hurriedly replied.

Lin Jiangbei took out an ampoule and asked while writing his name on it, "What are you doing in the torture department?" ”

"Guard!" Zhong San Fat Ping replied with his hands raised, "Responsible for guarding the prisoners in the basement cell." ”

Lin Jiangbei nodded, poured a third of distilled water into the ampoule with his name written, took a clean cotton swab, and began to sample on Zhong Sanpang's fingers......
