The police arrived quickly and cordoned off the scene.

Since Lu Qiqi is the criminal policeman of the City Bureau's Criminal Police Brigade and the first person to discover, she shouldered the heavy responsibility of the investigation without hesitation.

Lu Qiqi was very excited. It could be said that this was the first time she played such an important role in a homicide investigation. She felt that she was one step closer to success.

Hua Xiaochen also entered the scene as Lu Qiqi's friend and an important witness at the scene. He quietly observed the scene.

The victim was a young woman who was the first to enter the store. She was stabbed to death and thrown in the toilet cubicle, her body just blocking the cubicle door.

The young woman's purse and some items in the bag were turned out and thrown next to the toilet. The money in the purse was gone, and there was a blood-stained dagger with these things, and no fingerprints were extracted from the dagger. .

There is also a window on the wall of the toilet cubicle, and outside the window is a deserted alley.

Lu Qiqi was reasoning: "In my opinion, the murderer is probably a thief who wanted to steal the victim's property through the window. After being discovered by the victim, he killed the victim hastily, and then took the money and fled the scene."

The more Lu Qiqi thought about it, the more she felt that her reasoning made sense, so she immediately gave an order: "Go out and investigate if the passers-by have seen any suspicious people fleeing from here!"

When Hua Xiaochen saw that he was about to suffer, it was completely different, so he hurriedly said: "Wait a minute, I have a bit of a disagreement."

Lu Qiqi stared at Yuan: "We are handling the case very seriously, please don't bother unrelated laymen."

Hua Xiaochen said helplessly: "Officers, I think the murderer should be someone from the store, not someone from outside."

A middle-aged male policeman in his 30s asked, "Why does this brother think so?"

Hua Xiaochen pointed to the window of the cubicle and said, "Look at this window, it's so clean. If it was a thief who killed passionately, there should be a lot of blood stains on the window, so the window wouldn't be so clean."

Lu Qiqi retorted dissatisfied: "Maybe the thief wiped the windows clean after he got out!"

Hua Xiaochen tapped his brain: "A brain is a good thing, I hope you have one too. Would a thief who would leave a murder weapon at the scene clean the windows so carefully?"

"You!!!" Lu Qiqi blushed with anger.

The middle-aged male policeman nodded thoughtfully: "You make a lot of sense."

Hua Xiaochen saw that this person was quite capable: "So I think the murderer should be someone from the shop, and someone who has gone to the toilet."

Lu Qiqi refused to accept it and said, "Captain Zhao, don't trust him. I've also gone to the bathroom. Am I a suspect too?"

Without waiting for Team Zhao to answer, Hua Xiaochen replied first: "Of course you are not. You ran out as soon as you entered the toilet. No one would shout out immediately after killing someone so stupidly. Besides, the time you entered was too short, and the time for committing the crime was too short." not enough."

Team Zhao nodded: "Xiao Lu, do you still remember who has been in the toilet?"

Lu Qiqi blushed and shook her head: "I don't remember."

"This is troublesome, I can only ask the boss." Zhao team is going to find the boss.

Hua Xiaochen is happy, she doesn't remember and there is a buddy, buddy has a super memory, has a photographic memory, and remembers the order of going to the toilet clearly.

"I remember very clearly that the victim was the first to go to the toilet, then this college student, after the college student was this middle-aged eldest sister, and after the eldest sister was this burly man. These are the few people."

"Then you mean that the murderer is among these three?" Team Zhao looked at Hua Xiaochen.

"That's right, the murderer is among these three people, and the murderer and the victim still know each other!" Hua Xiaochen said firmly.

Lu Qiqi asked curiously: "How do you know that the victim and the murderer knew each other?"

"Because the victim has been looking at her watch since she came in, obviously waiting for someone. When she went to the toilet, she asked the boss where the toilet was, but when the boss said that the toilet was shared by men and women, she said she knew. This shows that the victim In fact, I have been to this store and know where the toilet is. When she asked the boss where the toilet is, she was signaling to the person she was waiting for to come to the toilet. But she didn’t expect that she would be killed in the toilet by the person she was waiting for. inside."

Lu Qiqi looked at Hua Xiaochen in surprise, her eyes widened: "Why do you remember so much? How come I don't know anything?"

"Because I have brains, but you don't." Hua Xiaochen looked at Lu Qiqi with a smile.

"You!!!" Lu Qiqi was furious again.

"Okay, stop making trouble." Zhao Dui said with a smile, "Mr. Hua, how do you think the murderer committed the crime?"

Lu Qiqi said first: "Since the murderer knew the victim, he must have tricked the victim into the toilet cubicle, then locked the cubicle, killed the victim, climbed from above to the next cubicle, and climbed out from above."

It seemed like this was the case, but Hua Xiaochen always felt that something was wrong, so he continued to observe on the spot.

Among the three people who have been to the toilet, college students and middle-aged beautiful women should be able to climb from the top of the cubicle. Only the burly and strong man can't climb from the top of the cubicle because his body is so strong. Go through that little gap.

Lu Qiqi was very excited: "In this way, only a middle-aged beautiful woman and a college student are suspected. We only need to check the victim's interpersonal relationship and see which of these two people she knew, and we can basically know the murderer. Who is it?"

Captain Zhao was a little moved, but he hadn't made up his mind yet.

Hua Xiaochen always felt that the matter was not that simple, and just now the forensic doctor said that there were strangle marks on the victim's neck, probably the murderer first strangled the victim's neck with a rope, and then killed the victim with a knife.

Lu Qiqi suddenly made a new discovery: "Captain Zhao, come and see, there are two ropes on this college student's seat."

Zhao Dui walked over quickly, and Lu Qiqi continued: "This should be the rope used to strangle the victim. Then, as I expected, this college student is the murderer."

Lu Qiqi continued to reason: "The college student and the victim knew each other before, but because of a dispute over something, they made an appointment to negotiate in this coffee shop. Unexpectedly, the college student had murderous intentions, and after following the victim into the toilet, he first strangled her with a rope to let her go. She couldn't cry out, then stabbed her to death with a dagger. Finally, she crawled out through the gap in the ceiling of the cubicle."

After speaking, Lu Qiqi glanced at Hua Xiaochen provocatively, and then walked towards the college student: "Be honest, you are the murderer in this case!"

The college student was terrified and panicked: "No... no, I used this rope to bind books. I didn't kill anyone! I was wronged!"
