Feng Sen chuckled: "There are indeed many cases in criminal investigation, the murderers are all killed due to mental illness, but it cannot be speculated that Zhao Rui has mental illness and killed his wife because of this, and there is no factual evidence to rely on." ”

"Didn't Brother Chu find broken hair in Aunt Li's inner cavity, as long as you compare Zhao Rui's DNA, if the result is consistent, isn't it the strongest and powerful factual evidence?"

Ye Fan's eyes were shining, and he felt that this was an excellent method, and there was room for refutation in other evidence, but the broken hair left in her body was irrefutable.

"You can't say that. Feng Sen swayed and did not praise Ye Fan's statement.

"Judicial handling of cases is to pay attention to procedures and legality, as far as all the evidence is concerned, there is no conclusive evidence pointing to Zhao Rui, and the police have no right to ask for Zhao Rui's DNA sample without the suspicion of a crime. ”

"Film and television literature is virtual, and criminal investigation pays attention to solid evidence, rigorousness, and cannot rely on intuition and assumption alone, which is a big taboo. "Feng Sen intends to teach Ye Fan the knowledge of criminal investigation.

"Zhao Rui is not a criminal suspect at present, the police do not have the cause to trace the other party's information, if the other party's information is obtained through improper channels, it is an illegal operation and violates the rights of citizens, even if it is really confirmed that Zhao Rui is guilty, he also has the right to appeal about the improper source of the evidence, and apply for the evidence to be invalid. ”

Ye Fan pursed his lips slightly, indeed, if the police and other judicial authorities can investigate citizens' information at will, won't the whole society be chaotic?

But the real reason for her suspicions about him could not be explained.

After a deep sigh, Ye Fan's deep eyes looked at Feng Sen and said, "If it can be proved that on the evening of April 26, Zhao Rui left H City and returned to Haicheng, right, can it be determined that there is a suspicion and an investigation?"

Feng Sen really didn't understand, why did Ye Fan hold on to Zhao Rui? In the previous conversation, she was obviously very sensible, but tonight she was a little ...... It's a disappointment.

At the time of the incident, Zhao Rui, as the closest person to the deceased, had already inquired about his whereabouts and confirmed that he took the high-speed train to the province and city on April 23, did not leave during the period, and returned to Haicheng on the afternoon of the 27th. ”

"Haven't you really left?" Ye Fan asked, and then said, "There is a situation that you may not know. ”

"At the end of February, the national middle school knowledge competition, G province won the second place in the overall score, the province held a commendation exchange conference in the province and city, and five students won the award, so Zhao Rui took five students to the province and city as the team leader, and went to the province and city for a total of five days. ”

"I asked the five classmates who went with me, and they all said that they didn't find any abnormalities in Zhao Rui during the five days, but on the afternoon of April 26, after a day's meeting, Zhao Rui went back to his room to rest on the grounds that he was not feeling well, and he didn't even eat dinner, and he didn't show up until after 7 o'clock in the morning the next day. ”

However, at about nine o'clock that night, there was a junior who was injured, and he thought that the teacher had medicine and went to Mr. Zhao's room to look for him, but no one opened the door after knocking for a long time, he thought that Mr. Zhao was asleep and didn't hear it. ”

"But what if it's not asleep, but not in the room?"

"Why is it so coincidental that he disappeared from everyone's sight from about 6 p.m. to 7 p.m. the next day on April 26, and it was during this time that Li Qiaojing was killed. ”

This is what makes her most suspicious, except for the unspeakable doubts.
