Han Xu asked some more questions, all focusing on Guo Feng's actions in Yaoyang City on the day of the incident. Guo Feng didn't hide anything and answered them one by one. Han Xu used some small tricks during the questioning process. After repeated verification, he confirmed that Guo Feng was not lying. And these questions are consistent with the survey results from Xizhi. Except for Guo Feng, who stayed in the hotel room when he was drunk that night, the rest of his actions were witnessed by witnesses. So his suspicion can basically be ruled out. Xizhi Yu Tianfang also ruled out Guo Feng as a suspect. The reason is that there is no direct expressway from Yaoyang City to Yancheng. If you take the provincial highway, it will take at least 6 hours to drive. A round trip takes 12 hours. It is impossible for Guo Feng to enter the hotel room at around 7 o'clock on the day of the crime, return to Yancheng like a magic trick, then calmly commit the crime after 9:30, and finally return to Yaoyang City.
According to investigation data from Xizhi, Guo Feng ordered room service at around 2 . The hotel staff can testify that Guo Feng was in the room at the time and smelled of alcohol. The time when Guo Feng had no witness was from 7 pm to 2 am. There were only 7 hours in total, which was not enough to travel back and forth between Yaoyang City and Yancheng City. Therefore, based on the time of committing the crime, his suspicion can be ruled out. But Han Xu always felt that something was not right, but he couldn't explain it. After leaving Guo Feng's residence, it was already past 9 . After a busy day, there is still no breakthrough in the case and it is stuck at the same point. Li Le didn't even find out the identity information of victim No. 3. In the huge database of missing persons, there was no match for the source of the body. The case is indeed very difficult. As soon as the two got in the car, Song Jiaer couldn't wait to ask, "Did you find anything?" Han Xu shook his head, "Nothing has been found so far, but I always feel that this Guo Feng is quite suspicious." "No way, the way he looked just now didn't look like he was acting! What's more, he had no time to commit the crime. A round trip from Yaoyang to Yancheng would take at least 10 hours, and he only had 7 hours , there’s not enough time at all.” "What if he didn't drive?" Han Xu guided Song Jiaer's thoughts. "Don't drive?" Song Jiaer smiled, "If you take other means of transportation, it will be too late. I have taken the bus from Yancheng to Yaoyang, and it is much slower than driving by myself." "What about the land route?" Han Xu also smiled. "You mean by water? Unless he has a yacht." Song Jiaer was stunned for a moment, thought of another possibility, and immediately ruled it out, "No, Yaoyang is not near the sea, and there are no rivers. It is an inland city. Even if Even if he has a boat, he can't reach Yaoyang City because water is not feasible." Han Xu nodded, agreeing with Song Jiaer's statement. Before Han Xu could say anything else, Song Jiaer kept talking, "We don't have a direct flight to Yaoyang here, not to mention that it's often delayed. Although the flight is fast, it still takes a lot of time to get from the airport to the city. less time.
It would be too late to change the phone and it would be too troublesome. The last means of transportation is the train. The current express trains are fast enough, but they are all authenticated by real name. Xizhi checked Guo Feng's movement track and found no record of Guo Feng taking an express train. " Song Jiaer eliminated all means of transportation in just a few words. "You are right. On the surface, Guo Feng did not have time to commit the crime. However, his behavior is very problematic. I always feel that things are not that simple." "Forget it, let's not talk about this anymore, where should we go next?" Song Jiaer didn't realize that it was already very late, and she was not tired at all from work. "Auntie, it's already nine o'clock in the evening. It's time to go back to bed." Han Xu pointed at the time on his watch and reminded. Song Jiaer curled her lips and said, "Ah, it's already so late. Okay, I'll take you back." "How about we go have a drink?" Han Xu tried to ask. "No, don't bother my aunt. You can go back and drink with Chengzi." Song Jiaer drove the car, put it into gear and started, putting an end to someone's delusions. … By the time Han Xu returned to the rented place, it was already past 10 . Cheng Zi had already come back and was lying on the sofa in the living room watching TV. As soon as Han Xu entered the door, he asked Chengzi if he had discovered anything in the afternoon. Orange was wearing bear pajamas and didn't look back. "I put my clothes in the bathroom, and you took the time to wash them for me! Damn it, you don't know what the garbage dump smells like! Brother, I almost couldn't come back!" "Throw it in the washing machine and press the switch and it's done. Do I have to do this?" Han Xu was convinced. "What you promised this afternoon can't be ignored!" "Okay, I'll wash it for you. Tell me, have you found anything?" Han Xu also took off his coat and threw it into the washing machine. Cheng Zi chuckled and said, "I found it, is there any reward?" "How about breakfast for three days?" "Are you too stingy?" Chengzi cursed, "Five days, no more." "Deal!" Han Xu came out of the bathroom after pressing the power button on the washing machine. Hearing Chengzi's tone, he must have found something. Cheng Zi said as if he was taking credit, "I dug through most of the garbage dump, and finally got something. The bricks have been sent to the Trace Inspection Department. We will give you the news tomorrow." "Is there any blood on the brick?" Han Xu asked. Chengzi nodded, "There is a large piece of blood on it, but it has been contaminated. Chief Zhao of the Trace Inspection Department said that the surface of this brick is too rough, and it is almost impossible to extract a complete fingerprint. If you are lucky, you can extract some incomplete fingerprints. But it is very likely that they do not meet the conditions for becoming evidence."
Han Xu sighed after listening to this, which was also expected. After all, most fingerprints extracted at the scene are blurred, incomplete, deformed, and overlapping, and the fingerprint system in the computer simply lists similar fingerprints. To identify a fingerprint, you must rely on the naked eye to mark, compare, and identify dozens of similar fingerprints one by one to draw a conclusion. The fingerprints on the rough bricks are most likely incomplete. In fingerprint identification, if the fingerprint to be identified is not clear enough, or the number of clear lines is too small, it is difficult to become strong evidence. It should be known that 13 features are required to identify the identity of fingerprints, and 8 features are also required to deny the identity. If this requirement is not met, the identification conditions are not met. This is also the basic requirement of the fingerprint identification identity comparison principle. In other words, if the incomplete fingerprints extracted from the bricks found by Chengzi do not meet the conditions for being used as evidence, then they will have no value and will be considered as a waste of effort. "Let's wait for news, what if there is a miracle?" Han Xu still maintained his optimistic nature.
