The two walked around but didn't find any good place to rest. Han Xu looked at the big hotel in front of him, "Get a room?" Song Jiaer ignored him, "It's noon, is it necessary to get a room to rest for a while?" "I think," Han Xu touched the back of his head, "It's necessary." "Go away, go back to the car and rest for a while!" Song Jiaer said unhappily. Han Xu had no choice but to follow the policewoman in the car for a while. After waiting for the sun to pass at noon, the two set out to investigate the case again. In fact, when encountering a case, most of the time, criminal investigation is done day and night, which is very hard. But when it comes to Song Jiaer, she doesn't look tired at all, but is in high spirits. Han Xu has to admire this.
Maybe some people are born to do this job. Han Xu drove all the way and followed the navigation to the vicinity of the second crime lighthouse. This is a scenic spot in Yancheng, very close to the famous Golden Coast Beach. The crime lighthouse is within the scope of this scenic spot. The scene is still cordoned off. It has been a while since the incident. Song Jiaer followed Han Xu's steps and said, "Victim No. 2 Gong Li left the hotel on the 7th and disappeared. Her body was not found until the 18th. The autopsy report from Xizhi showed that the victim Gong Li died around the 16th. So from the 7th to the 16th, there were almost 9 days. Could Gong Li have been imprisoned by the murderer like Victim No. 3?" Han Xu stopped and replied, "It is very possible! Victim No. 2 may have been imprisoned for about 9 to 10 days, but Victim No. 3, according to Xiao Xiao's autopsy report, was likely imprisoned for a longer time. But the question is, why was Victim No. 1 Liu Lisha killed on the day she disappeared?" "Yes, and the blunt force injury on the back of Victim No. 1 Liu Lisha's head was caused by a brick, which is different from the other two victims. Could it be that these cases were not committed by the same murderer?" Song Jiaer seemed to have found the key point. Han Xu nodded and said, "I originally guessed so, but there are still many doubts that cannot be explained." "What doubts?" Song Jiaer asked curiously. "For example, the three cases all seem to be murders on the surface, and the target selection is surprisingly consistent. The victims are roughly between 25 and 30 years old, and they are in good condition. What's more strange is that each victim has injuries, but no male genetic material has been extracted. Are these just coincidences? If the murderer is not the same person, these doubts are also difficult to explain, and they don't make sense logically." After Han Xu's analysis, Song Jiaer was overwhelmed, too complicated. "Then how should we investigate?"
Han Xu smiled and said, "We have very few clues now. In addition to the drop of blood you extracted, there is only a brick. So, we have to investigate the crime scenes and people involved in the three cases and collect more valuable clues." Song Jiaer understood, no wonder Han Xu asked her to investigate the case together. The main purpose was to re-investigate the two crime scenes. The second lighthouse where the crime occurred stood like a postcard on a seawall that extended to the sea. This seawall is a tide-proof and wave-proof embankment built along the tidal estuary and the edge of the coast. Its function is to defend against the invasion of tides and wind and waves. From a distance, the No. 2 lighthouse looked like it was wearing blue and white clothes, hidden between the sea and the blue sky, with a romantic atmosphere. So this lighthouse has also become a check-in spot for many couples. The chains next to the seawall are full of various love locks. Han Xu leaned down curiously and checked the words left on the locks one by one. So-and-so and So-and-so, the seas run dry and the rocks crumble! So-and-so and So-and-so, forever! So-and-so and So-and-so, die together! XX and OO, stay in prison forever! "What's so good about this?" Song Jiaer had no romantic cells at all. She frowned and looked at these love things, a little confused. "Are you made of wood? Don't you know what romance is?" Han Xu sneered. "What's the use of romance?" Song Jiaer replied disdainfully, "Can you help us investigate the case?" "Hey, how do you know how to investigate the case? Do you need me to write a report for you and transfer our second team?" Han Xu said bluntly. "Really?" Song Jiaer was actually excited, "A man should keep his word!" Han Xu ignored someone and walked straight to the No. 2 lighthouse. It was only a few days after the incident, and it was still in the blockade period, and there were no tourists sightseeing and taking pictures. After showing his ID, Han Xu led Song Jiaer into the scene. Obviously, the murderer still took the water route this time. After checking the surveillance video of the beach scenic area all night, Lao Zhang concluded that no suspicious persons were found. Even if it is inferred that the murderer took the water route, or the sea route, some work must be done. Although Lao Zhang found nothing, he also proved from another side that the murderer had a boat. All three cases happened at the lighthouse, and the murderer took all the waterways. No matter how you look at it, these are all serial murders committed by the same murderer. But Han Xu always had a hunch that told him that the case was not that simple.
With doubts, Han Xu came to the entrance below the lighthouse. "It was locked here. The murderer used a large wire cutter to violently cut the copper lock, which shows that he was quite strong." Song Jiaer said the previous inference. Han Xu nodded, "Is the person who reported the case the administrator here?" "Yes," Song Jiaer said without any pause, "The person who reported the case has been working in the scenic area for more than ten years. When he came here for routine inspection on the morning of the 18th, he found that the copper lock had been cut off. When he went in, he found Gong Li's body." Han Xu looked at the case pictures shared by Xizhi and spoke out his doubts, "The second case is very special. The murderer did not fix the victim on the top floor of the lighthouse like the first and third cases, but directly threw the body on the bottom floor. Although there are many cuts on the victim's back, no matter in number or depth, they are far less brutal than the first and third cases!" "What do you mean, this is very likely not the first crime scene, but just a place to dump corpses?" Song Jiaer analyzed the key point he wanted to say from Han Xu's words. "Smart," Han Xu continued, "and the lighthouse here is obviously different from the other two. This is a place for couples to check in." "What do you mean?" Song Jiaer didn't understand. Han Xu explained, "This time the murderer seemed to have deliberately let people find the dead body earlier." "Is he provoking us?" "I don't think so." Han Xu seemed to think of another possibility...
