The criminal police inquired about Zeng Ji again. Zeng Ji stated: "I took the express train back to Nanguang City at Dongyang Station. ”

Based on his statement, the police checked with the conductor of the train and replied that they had no impression of the passenger, Zengji.

As a result, the police detained Zeng Ji. According to Zeng Ji's confession, the police found a staff member with a square face and about 40 years old in the luggage storage area of Nanguang Station for verification, and the staff replied: Receiving a large number of passengers every day, there is no impression of Zeng Ji.

The police task force determined that the playwright Zeng Ji was a suspect in the murder of Wu Ying based on the following aspects: Zeng Ji had an unclean relationship with Wu Ying, and while her husband Xiao Long was out to participate in a sailing competition, he went straight to a hotel in Dongyang City to open a room and cheat. Although Zeng Ji confessed that he did not hide this fact, he said: In the process of watching the fireworks show from the hotel's rooftop square, he did not notice Wu Ying's sudden disappearance from his side. The statement doesn't make sense.

Assuming that Wu Ying went somewhere alone, he would definitely greet Zeng Ji before leaving. Regarding this, the suspect Zeng Ji himself said that it was incredible. Even if you run into an acquaintance on the rooftop square, you will inevitably return to the room to meet him afterwards for fear of exposing the fact that you have opened a room with Zeng Ji in the hotel and escape for a while. What's more, Wu Ying's luggage and tow box remained intact in the hotel room. This phenomenon, together with Zeng Ji's confession, made the police feel that the suspect was full of suspicions.

However, the fact that Wu Ying disappeared from the rooftop square was not known to a third person, only the confession of the suspect Zeng Ji. Besides, he didn't report to the hotel in time. From checking out at the main service desk at about 8 o'clock the next morning, to setting off from the hotel with his girlfriend's luggage and his own luggage trailer in both hands, he didn't reveal a single tone to the hotel's general service desk.

According to the police, the suspect's behavior was extremely unnatural. Of course, it's not that I can't understand Zengji's excuses, it's because of the secret tryst trip, so I can't tell anyone, including the front desk. But the female companion Wu Ying is gone, and she herself is not familiar with the place in Dongyang City, and her eyes are black, Zeng Ji should know about this situation. She left the rooftop square without saying goodbye and did not return to her house in Nanguang City, so it should be assumed that something major had happened to her. Strangely, Zeng Ji did not take any countermeasures. It stands to reason that Zeng Ji should at least inform the hotel attendants of the situation and ask them to help find it throughout the hotel. However, he didn't even fulfill this minimum obligation, and just called the front desk and said, "Madame seems to be out, may I ask her if she has any message." The staff at the front desk also said that there was no impression that he had called to inquire, and that he left the hotel as if he had fled the next morning.

Arriving at Nanguang Station, Zeng Ji entrusted Wu Ying's luggage tow box to the station's luggage storage for safekeeping. Why didn't he take Wu Ying's luggage tow box home and leave it at the station instead? Maybe the luggage tow box can't be disposed of at will, or maybe it will show clues sooner or later if it is thrown somewhere, but I want to wait until the wind has passed to go to the station to retrieve the luggage tow box before disposing of it. Moreover, he has not gone to the station until now to retrieve the luggage tow box of the deceased Wu Ying.

What's more, the body of Wu Ying, who was strangled to death by Zeng Ji with a rope, still appeared in the woods and clearing near his house.

According to the analysis of the criminal police, Zeng Ji's most suspicious action was on the 17th of returning to Nanguang City.

His nanny said: "Zeng Ji returned home at about half past twelve at noon on the 17th, and when he arrived home, he looked exhausted, and he was still carrying the brown suitcase he brought with him when he went on a trip.

Zeng Ji himself said: "I rested at home for a day during the day. I left my house at around 6 p.m. and took a taxi to a movie theater, which took about two hours. After that, I went out into the street, climbed to an open-air beer shop on the roof of a building, drank three cold beers, and took a taxi back home around 11 p.m. ”

Zeng Ji explained: "There are a lot of people in the cinema and the open-air beer shop, but I don't meet a single acquaintance. ”

After investigation, the cinema and the open-air beer shop were indeed full that night, especially the open-air beer shop was shoulder to shoulder, and the waiter of the open-air beer shop reported that there was no impression that Zeng Ji had come at all. The female conductor at the ticket window of the movie theater, the female ushers in the venue, and the audience also reported that they had no impression of Zeng Ji. Generally speaking, as long as there is nothing particularly noticeable about his appearance and no strange words and deeds, his ordinary appearance is like air and should not leave any impression on the people around him. The movie "Disappearing" is a film that has been in theaters for a long time, and Zeng Ji is very likely to have seen it before leaving for Dongyang City. Assuming that he stated the plot and images of the movie, it does not absolutely prove that he watched the movie on the night of the 17th. The taxi driver reported that he did not have the appearance of the passenger Zeng Ji in his memory. In short, the above situation does not constitute a condition for him to have no time to commit the crime, nor is it a condition for him to claim that there is no time to commit the crime, and it is logical to assume that Zeng Ji deliberately disguised himself.

Zengji lives alone, and the nanny comes to his house during the day and leaves his house in the evening. Zeng Ji returned home after leaving the cinema and the open-air beer bar on the evening of the 17th, and he was completely alone, and no one would know about him or ask him what he had done. Suppose that at about 8 o'clock that night, according to the pre-made murder plan, he lured Wu Ying to his house for a while, and then took her for a walk in the nearby woods after 11 o'clock, and then strangled her......

The police task force believes that Zeng Ji had a motive for killing Wu Ying. Often, once an unclean relationship with a married woman occurs, it is easy to give rise to such cases. A woman's extramarital affair is due to her husband's treachery, which is enough to make her indulge in the man outside and burn her own life, and immoral and unhealthy behavior is always accompanied by a sweet sense of despair.

In this regard, men are too protective of themselves, and extramarital affairs often go the opposite way at first, and then often reverse 180 degrees afterwards. Because, men are afraid of women hysterically pestering. The ending is mostly due to the development of events that are out of control, and they fall into a desperate situation where they have to let the woman they once loved disappear from their side permanently. So far, there have been countless cases like this, especially among middle-aged men of culture, who often hate endless emotional entanglements.

What is the situation in this case? First of all, why did Zeng Ji return to Nanguang City from Dongyang City alone? Secondly, why didn't Wu Ying continue to spend the night with Zeng Ji at the hotel in Dongyang on the night of watching the fireworks show?

Isn't this the result that Zeng Ji originally wanted and carefully designed for this? That is to say, if they went to the hotel in Dongyang City together to steal joy and then returned to Nanguang City together, the traces of the crime of murdering Wu Ying would be clearly visible. Assuming that Wu Ying never saw her again after her sudden disappearance from the rooftop square, then Zeng Ji was dismissed from suspicion of killing Wu Ying. For this reason, Zeng Ji deliberately left the hotel in Dongyang with Wu Ying's luggage tow suitcase, took the express train back to Nanguang City, and then left her luggage tow box at the luggage office of Nanguang Station. He did this entirely to forge the illusion that Wu Ying had suddenly disappeared from that hotel in Dongyang.

According to this plan, Zeng Ji may let Wu Ying go to other hotels in Dongyang City alone. In terms of Wu Ying, what Zeng Ji said, there is no doubt that he blindly believes and follows blindly.

However, the hotel in Dongyang could not confirm that Wu Ying had walked out of the gate, and it was crowded that night due to the large number of tourists who went to the rooftop plaza to watch the fireworks, even if the female travelers staying at the hotel were out.

The above is the reasoning of the police task force on the criminal traces of the suspect Zeng Ji.

However, there are also objections to this reasoning: although it is generally logical, there is no empirical evidence. Not only that, but there may also be accomplices. Assuming that Zeng Ji had a motive to kill Wu Ying, then the person who had a stronger motive than him to kill Wu Ying was not Wu Ying's husband Xiao Long? If Xiao Long had known in advance about his wife's itinerary and destination for his wife's secret date with Zeng Ji, it was entirely possible that he would have killed his wife and blamed his rival Zeng Ji.
