crime profiler in the dark

"Then what does she usually do in the dormitory?" Bai Haolin asked.

"I spend most of my time on my phone."

The three girls didn't give any clues. Principal Zhang saw that they were fine and sent them away. Seeing this, Bai Haolin excused himself to go to the bathroom and left the principal's office. He caught up with them and said to the girl with ponytail:

"Sorry, can I ask you two more questions in private?"

The other two girls consciously left first. The girl with the ponytail didn't know what the police were looking for her, so she shrank nervously. Bai Haolin smiled: "You didn't do anything wrong, I see what you have What I want to say is that you actually know something about Li Mei, but it’s just not convenient to say it just now, right? Is it because Principal Zhang is here?”

"We are all afraid of hurting others by saying the wrong thing." The girl with the ponytail replied in a low voice.

Bai Haolin understood that she was worried that the tragedy like the class teacher would happen again, so he said: "I am a policeman, not a reporter. We have to verify every word you say, and we will not disclose the important clues of the case to the public. , so you don't have to worry about it."

The girl with the ponytail nodded.

"Has Li Mei dated anyone?" Bai Haolin asked.

"I don't know, it's just that one day, when I went back to the dormitory to get something, I heard her talking on the phone on the balcony, and she spoke in a very sweet tone."

"What did she say?"

"I can't hear clearly, I can only vaguely hear words like 'I'm so happy' and 'Wait for you'."

Li Mei has a boyfriend?Is it the murderer?Bai Haolin secretly felt strange: "Who is she talking on the phone with?"

"Hearing her tone of voice on the phone, it should be with her boyfriend. I don't know who it is. I took my things and left without asking her. It's just—" The girl with the ponytail hesitated. speak.

"Just what?"

"Actually, Li Mei and I used to talk because the bed was facing each other, but she changed later."

"How to say?"

"She didn't play with her mobile phone very much before, but then she became, um—" The girl didn't know how to express it. She thought for a while and said, "Do you know IMG?"

"IMG?"

"Well, an application software on the phone, used for chatting, it has a function to find people nearby."

"You mean Li Mei uses this chat software to communicate with others?!" Bai Haolin seldom plays with his mobile phone. The mobile phone is just a communication tool for him. He really doesn't know about such a new thing as IMG.

"It's very possible. Because I also play games by myself. Once when I went out to eat with Li Mei, I heard her mobile phone ringing. The sound was the notification sound when IMG's text message arrived. It was very special, and I recognized it immediately. At that time I also asked her who sent it, and she said it was a very interesting person nearby."

Internet dating? !That's how the murderer found her? !So it looks like the murderer is from the town?Li Mei was killed just for responding to his message?Bai Haolin thought to himself, and asked again, "When did this happen?"

"Probably a month after school starts."

"Okay, thank you."

Bai Haolin quickly returned to the principal's office, just as Fang Xiang and Police Officer Liu also came out, Bai Haolin roughly recounted what the girl with the tail had said, and Fang Xiang said excitedly:

"Great, I'll immediately apply to retrieve all the chat messages on Li Mei's IMG!!" Li Mei's cell phone is among the police evidence, and they only checked the communication records and text messages, not IMG. application software.

Fang Xiang immediately called the Technical Inspection Office of the Support Department and reported the matter to Sergeant Chen at the same time.

The trip was fruitful. In addition to finding out how Li Mei contacted the murderer, he also heard a strange nursery rhyme. These two clues can deepen the understanding of the murderer.
