It makes sense for the delivery boy to appear at the crime scene, right?

In the toilet, the innermost door was hidden, and blood had already flowed to the bottom of the steps.

Su He slowly pushed open the door and saw that it was the woman who was sitting next to him earlier.

The woman was on her knees, leaning against the wall, with wounds on her neck and bleeding from her chest and stomach.

From the time the woman got up to go to the toilet to the time the body was found, it took more than half an hour, why did no one find it during the period?

The police were questioning the person who first found the body, a trainee in subject two, and she found that blood was flowing out, the door was locked at the time, and she found through the crack in the door that there was a dead person inside.

The woman was killed, the toilet door was locked, how did the murderer do it?

Su He carefully checked the door lock, there were traces of prying with a blade on it, he walked to the side room, pulled the door, took out the key, and with a gentle flick, the door was locked.

The murderer masters a certain lock picking technique!

Apart from this, Su He found nothing else, and not long after, Zhou Bing came over with a forensic doctor.

"Su He, what's going on inside?" As soon as Zhou Bing looked up, he saw Su He.

"Today's subject 2 exam, I just finished it... Ah, I thought you asked why I was here..." Su

He found that Officer Zhou had skipped the topic directly, so he said positively: "A woman was killed, I suspect that the murderer knows a little lock picking skills... There was a power outage here before, it should be man-made ... By the way, the victim's bag is at the staff, I'll go get it. "

Open the bag, inside is the woman's ID card, Wang Qian, 34 years old.

The police did not find the victim's mobile phone at the scene and contacted the family through the ID address.

Not long after, a man led a little girl to arrive, the man knelt on the ground and cried silently, the little girl also cried when she saw this, crying and shouting: "Dad, I want mom... "

Uncle police, don't arrest my mother... At night, my father goes to work, and my mother wants to sleep with me..." The

onlookers couldn't help but secretly wipe their tears, there was a homicide case, the entire subject two exam site was blocked, and the police registered and checked suspicious people one by one.

The police immediately retrieved the surveillance video, but found that there were twelve minutes missing halfway, apparently the murderer took advantage of the gap between the power outages to commit the crime.

Zhou Bing turned his head and glanced around and asked, "What about Su He?"

Rong Xue was sorting out the information, looked up and said: "Su He said that he couldn't help and went to deliver takeaway."

While riding a bicycle, Su He thought, the system rewarded advanced lock picking skills, was it just for the moment in the toilet just now?

If it is still useful for this case, how can the clues be sought?

"Ding, you have a new takeaway order, please deal with it in time."

The weather is getting hotter and hotter, today's maximum temperature has reached 33 °, Su He with a popsicle in his mouth, climbed up to the sixth floor in one breath.

"Hello, Meituan Takeaway!"

Su He's phone call was not answered, and knocked on the door.

After waiting for a minute and no one opened the door, Su He knocked on the door while calling.

After waiting for another two minutes, Su He still had two lists in his hand, and seeing that the time was running out, he sent a message to the customer.

"Hello, your takeaway arrived, no one answered your phone calls and knocks, I returned the takeaway to the merchant."

Delivery often encounters this situation, some customers fall asleep after ordering takeaway, and if they can't be contacted, Su He will report to the platform and return the meal to the business.

He had also tried to leave the meal directly at the door before, lost the meal once, and after receiving bad reviews and complaints, he did not dare to do it again.

Su He walked downstairs, and at this time a man with a mask walked upstairs and passed by him.

After going downstairs, Su He got into the battery car and suddenly found that there was an advertisement for unlocking the battery car next to him.

It wouldn't be such a coincidence, would it?

Su He still has two lists in his hand that he has not sent, and if he doesn't leave, he will time out.

Su He was just about to leave, the phone called, it was the customer who did not answer the phone just now, let Su He send it.

Helplessly, Su He had to run again, and the man who opened the door was the man who went upstairs just now, he said that he temporarily took a job of unlocking and forgot to bring this mobile phone.

Gave away the next two lists, and the last one overtimed and deducted him three dollars.

At this time, Rong Xue's phone called.

"Su He, there was another murder in the Huapu community, a man and a woman died..." When

Su He rushed to the scene, the downstairs was already full of people, and Rong Xue handed Su He a pair of shoe covers and gloves.

As soon as I entered the door, there was a corpse, a middle-aged man, covered in blood, with multiple wounds on his body, and the police were taking pictures.

The room was disheveled, with blood everywhere, and a female corpse lying on the sofa in the living room, with several wounds on the back of her neck and back.

On the wall of the living room, the suspect also left a blood book.

Four big words: blood debt and blood payment.

All the policemen were doing their jobs, and Su He wandered around inside, and found that he couldn't help anything, so he went downstairs and mixed into the lively crowd.

"Two dead, a newlyweds, just a few days after getting married, I don't know who is so ruthless

..." "I thought it was two people quarrelling, I just walked out the door, and there was no sound, I didn't expect to kill..." Su

He listened to the gossip for a while, and did not hear anything useful, sighed, he found that this criminal investigation consultant was really a little redundant.

In the two years that he was an assistant policeman, in addition to maintaining order, he fought wits with small traders and hawkers, and he did not know anything about criminal investigation, and the system rewards him for skills in life, and solving cases was not at all.

Looking at the time, at two o'clock in the afternoon, Su He suddenly remembered that he had not eaten lunch, so he came to the canteen of the Public Security Bureau.

At this time, the cook and waiter were resting, Su He walked into the back kitchen to heat up the meal, there were two murders in the morning, most of the police in the public security bureau were dispatched, and there were more leftover meals at noon.

After eating, Su He packed five more copies, walked out of the public security bureau and gave three copies to Dong Yong and them, and came to the hospital with the other two.

As soon as she walked upstairs, Su He heard the nurse's sister talking about the murders that occurred in the morning, both of which occurred in places with many people, and the news spread quickly.

"The woman who was killed in the toilet of the second subject is Wang Qian, a nurse in the orthopedic department, and I don't know who she offended?"

"I heard that she was stabbed a lot, and the one who can do this must be her husband... It's possible that her husband found out that he was cuckolded..." "

Don't talk nonsense, Wang Qian and her husband have a good relationship... I have the latest news here, Wang Qian's best friend, pediatric nurse He Jiru and Director Tang Mu of the orthopedic department were killed at home..."

"Ahem!" A nurse looked up and saw Su He standing there motionless, and hurriedly lowered her head and whispered: "Death delivery man Su He is here, he has been looking at us, everyone don't look at him... This morning, someone photographed him also taking subject two..."
