Zhao Shiyi and Captain Guo and others looked carefully. After a while, they couldn't help but give a thumbs up. However, even if they found out the letters were written by the same person, what good would it be? We still couldn't find the murderer.
As if sensing their expressions, I said, "It's okay. With the handwriting, we can get proof. As long as we can find a suspect and compare the handwriting, the evidence chain will be closed."
We left Zhao Xiaoxin's room. When we came down, all the police officers had returned, but they all said they hadn't found Xiaoxin. However, this was within my expectations. I suddenly saw a piece of information sent to me by He Xin, and a flash of inspiration struck me. But I couldn't reveal this matter yet, otherwise the murderer would definitely not admit it.
So I pretended to know nothing and continued to search the island with everyone. Zhang Keying has been following me. It wasn't until after 4 AM one day that we finally managed to get some sleep. We slept until more than 11 o'clock the next morning before most people woke up.
After waking up, Professor Huo asked us to gather in the hotel lobby. When we arrived, Professor Huo said to all the students present, "I'm very sorry to tell you that due to Xiaoxin's matter, this graduation trip will have to be canceled. But don't be sad, you can still stay at the hotel for these two days, but you cannot go out!"
When the students heard this news, they were very sad. But compared to one person disappearing here, no one complained. Seeing that there was nothing to do, they went back upstairs.
Zhang Keying and I naturally couldn't just spend these two days idly. Besides, Professor Huo's mention of two days was just a rough estimate. His main meaning was that we couldn't leave until Zhao Xiaoxin was found.
Therefore, if we wanted to leave Rainbow Island quickly, we had to find Xiaoxin as soon as possible.
When I walked out of the hotel, I saw Captain Guo busy. He led some people, sweating profusely, towards me. "Detective He, we've been searching for hours and still have no leads. Moreover, the kidnapper hasn't called Zhao Shiyi. I think it's not for money."
"It's been more than 6 hours. If it were for money, he would have called by now. I wonder why he's targeting Xiaoxin. Speaking of which, aren't Yu Zi and Zhao Xiaoxin in the same dorm? Is this related to them?"
As I spoke, Captain Guo seemed to remember something and immediately had people protect Yu Zi and the others, fearing that the murderer would attack them.
This time, we absolutely cannot let anyone else disappear. However, not far from the mailbox near the island's pier, I suddenly saw an envelope sticking out. It read: "For Mr. He Sheng's personal attention!"
This was actually a letter for me. I immediately became vigilant and took it to look at it carefully.
This time it was another terrifying message: "Detective He, it's me again. Are you very surprised? I'm telling you, Xiaoxin is just the beginning. At 2 PM, I will abduct another person. Haha, you can't stop me at all. If you can't prevent this from happening this time, I will take both of their lives. Think about it yourself. I will make you feel utterly useless from now on. As long as they die, you will lose all confidence in solving cases. Haha, I just want to see your utterly despairing expression! This time, it's the same as usual, don't let anyone know about the matter between you and me, otherwise I will immediately execute them!"
I observed that the handwriting was exactly the same as on the previous letters. It was indeed this person. If we were to judge by writing habits, I believe it should be from a male, though it's not impossible for a woman with masculine characteristics.
As I put away the letter, someone called me from behind. I turned around and found it was Zhang Keying. She asked me what I was doing. I didn't dare to reveal the matter of the letter, otherwise I would be going against that guy's wishes, and I couldn't let him execute them.
"Nothing, Keying. Be careful lately. We are all on guard. The murderer will probably abduct more people!"
"Didn't you receive another warning?"
I thought about it but didn't dare to say anything. In the end, I gave up. We had guarded so tightly before, yet people were still taken away. This time, I didn't want to trouble Officer Guo and the others.
However, at 1:50 PM, Gao Mingqiang suddenly called me. His tone was very anxious: "Team Leader He, something's happened. Captain Liu is missing!"
"What? Weren't you guys together?"
"We only had time to set off just now. Captain Liu was with us, but before boarding the ship, we couldn't find him. A female police officer said that before boarding the ship, she didn't know what happened and left on a motorcycle alone."
"Could it be, could it be that she also received a threatening letter?"
I said in horror. Gao Mingqiang frantically asked me about the threatening letter, but I didn't answer. It wasn't until I reacted that I yelled, "Don't come over. Immediately dispatch to find him. I'm coming back now!"
I left these words and immediately found a speed boat to go back to Guangming City. Zhang Keying also followed me.
After a while, we returned to the dock in Guangming City. Xiahou was waiting here. Seeing us arrive, he led us into a police car: "We are already investigating the surrounding road sections. He Xin is checking using mobile phone signals, but found that the last place Captain Liu used his phone was nearby. It seems he turned off his phone."
"Earlier on Rainbow Island, we checked Xiaoxin's mobile phone signal, and the result was also that we couldn't find anything. Damn it, this kidnapper is too cunning!"
Xiahou didn't know what happened to us on the island. I had to tell him. After knowing, he said, "He actually dared to notify you that he was going to kidnap someone? How arrogant. This is the first time I've encountered such a criminal!"
"That's right. Well, we have to find Liu Yuning as soon as possible!"
We followed the dock and searched the surrounding area. This time, because it was Captain Liu who was missing, Director Zhang dispatched hundreds of criminal investigators to us and contacted many police officers from nearby police stations, all to find him.
Near a road by the dock, I carefully observed and indeed found traces of motorcycles passing by. According to the direction of the tracks, Liu Yuning had likely headed towards Kaiming East Road not far away. However, there was a fork in the road about a kilometer away. Gao Mingqiang and I came to the nearby traffic management bureau. Theoretically, we could see her passing through the surveillance.
Sure enough, with the help of several traffic police officers, we saw Liu Yuning riding a men's motorcycle speeding through the area at 12:11 PM on June 9th. In the information provided by the dashcam footage in the vicinity, it was found that after passing through Kaiming East Road, she directly entered Zhongshan Road nearby. The entire process was basically captured. Finally, we found her getting off the motorcycle in a very remote place, and there was no more surveillance footage.
