Professor Yang Chengxun, a well-known authority on criminal investigation technology who is known as the "originator of China's polygraph industry", shouted that Sun Mou (later renamed Sun Shiyan), who was considered by netizens to be the biggest suspect in the Zhu Ling case of Tsinghua University, to conduct polygraphs.
Professor Yang Chengxun said that in the case of no substantial progress so far, the truth can be found by polygraph detection. The principle of polygraph is to protect innocent people, and it is better to let go of a bad person than to wronged a good person. We should get justice for Zhu Ling and her family, there is always a truth to things. ”
Many years have passed since Zhu Ling's poisoning case, and Zhu Ling has also passed away with regret, but the suspect is at least at large. At first, people focused their suspicious eyes on Zhu Ling's classmate Sun, but there was no conclusive evidence. If there is a suspicion, if there is a polygraph technique, why not adopt it? If it is proved that Sun is indeed a suspect, Zhu Ling can be given justice, and Zhu Ling can really rest in peace; If it is proved that Sun is indeed not suspected of committing a crime, he can also return Sun's innocence and not live under suspicion.
We hope that this case will not become an unsolved case, we hope that every case will not become an unsolved case, as long as there is a little clue, as long as there is a little turnaround, we can not let it go, as long as there is a glimmer of hope, we can all give it a try, do not let go of a bad person, do not wronged a good person, would rather let go of a bad person, than wronged a good person!
