Detective Li Changyu said there was still a chance that YINGYING ZHANG would survive?

Deng Hong, a famous lawyer in China who cares about the YINGYING ZHANG case, discussed the case with Dr. Li Changyu, a Chinese detective and an American criminal expert, this morning, and revealed Dr. Li Changyu's views on the YINGYING ZHANG case to reporters. It is believed that there is still the possibility of survival, but we should go all out to find all clues and find Zhang's whereabouts as soon as possible.

Lawyer Deng Hong told reporters that when the YINGYING ZHANG case happened, Li Changyu was preparing to give a lecture in Eastern Europe. Before leaving, he received help from the Illinois police investigators, and Li Changyu put forward ten suggestions for solving the case. Later, the FBI took over the case, but did not continue to participate because of giving lectures in Eastern Europe. However, since the case involved the safety of overseas students in China, he immediately learned about the latest progress through the media after returning to the United States. He said that although the suspect was arrested, the case was not solved until the whereabouts of YINGYING ZHANG were found.

Li Changyu said that there are three motives for kidnapping cases. One is money, which is used to extort money from family members; the other is that gangs kidnap opponents for illegal transactions in exchange; and the third is to meet abnormal sexual needs. In this case, the motive is probably sexual demand. In the case of sexual kidnapping, 90% of the victims are women, while the traditional suspects are white men, aged between 25 and 37, with high IQ, who have suffered sexual setbacks or abuse during their growth.

Li Changyu said that most suspects put their victims in hidden places to vent as sex slaves, and a few cases killed the victims immediately after satisfying their sexual venting. If the victim was hidden in a place to be a sex slave, the suspect has been arrested now. Unless someone helps him take care of the victims, the longer it takes, the less chance he has of survival. Therefore, the police should try their best to find the whereabouts of the victims in recent days.

Li Changyu, who has handled countless cases of missing persons for more than 50 years, put forward some suggestions for finding clues about missing persons, such as drawing a search circle from big data such as the suspect's car, refueling times, gas station videos, the location of the suspect's mobile phone and the location of the suspect's credit card, and carefully searching the places where he has stayed, worked and lived to see if there is a secret room, basement, other cars and victims in the trunk of the car.

Li Changyu said that this perverted kidnapper is often not just a crime, so investigators must investigate the place where he once lived and worked, and understand his modus operandi. These criminals usually have psychological problems, and they will return to the scene as sympathizers. On the one hand, they will know the situation of the case, on the other hand, they will get psychological pleasure from it because the police can't solve the case.

Regarding how to protect themselves, Li Changyu suggested that, first of all, criminals often win the trust of victims, such as claiming to be policemen and professors, and then they will deliberately provide some help, such as free transportation and taking the initiative to buy drinks. We must guard against these seemingly kind behaviors and insist on seeing their documents clearly; Second, don't act alone. Criminals often target some single women. Furthermore, don't trust strangers, and don't casually enter the homes of strangers or people who don't have deep contacts. Many serial killers gradually gain the trust of women or children and lead them to their homes or hidden places they set up to start their actions.

I hope YINGYING ZHANG is still alive. Pray!
