Pay tribute to Zhang Xin, the "divine pen Ma Liang" in the criminal investigation community

A pen made the suspect in the silver case appear in his original form, which was Zhang Xin, who was called "Ma Liang of the Divine Pen", but he had already left us and died at the age of 58 at 19:00 on October 20, 2018. But his portrait will always dissect how many people have been killed for us.

In 2016, the Gangmun 8.05 series of rape and murder cases of women was broken, and the criminal suspect Gao Chengyong was successfully arrested by the public security organs in the commissary of a school in Baiyin City, and after preliminary examination, he confessed to the crime of killing 11 people. At present, the trial of the case is proceeding in an orderly manner. In the process of investigation of the case, there was a group of portraits depicting the appearance of the suspect, and the CCTV reporter exclusively interviewed Zhang Xin, a special criminal investigation expert invited by the Ministry of Public Security who participated in the investigation of the case, that is, the portrait, and he told the little-known story that occurred in the investigation of the case.

The criminal investigation circle "Ma Liang" has cracked more than 700 major cases

Zhang Xin is a senior criminal technology engineer of the Shanghai Railway Public Security Bureau, the first batch of eight specially invited criminal investigation experts of the Ministry of Public Security, and the chief simulation portrait expert of China. From the police for more than 30 years, he has devoted himself to the study of analog portrait technology, and assisted the police in solving more than 700 major criminal cases of various types through simulation portraits and analytical reasoning.

A pen that makes the serial murder suspects appear in their original form

In 2002, there was a series of homicides in Xining, and because of the presence of witnesses, the Qinghai police thought of Zhang Xin. They hope to use the magical brush in Zhang Xin's hand to outline the true face of the criminal suspect.

Zhang Xin worked there for less than four days before finishing the portrait. Relying on the portrait provided by Zhang Xin, the Qinghai police quickly locked down the suspect, and the case was solved in ten days. Just as he was preparing to leave Xining, the Gansu police came to Xining and found Zhang Xin, hoping that he could help paint a portrait of baiyin's series of cases.
