Her head stabbed for no apparent reason, and her eyes shook. Her brain was shrouded in blood, and the puppet in front of her seemed to suddenly grin a strange grin at her.

“... Sister-in-law... You save me.... I'm so miserable...."

"What's wrong?" Xing Yi saw that something was wrong with her, and secretly stabilized her falling body.

“.... I'm fine. Feeling the reassuring power coming from her shoulder, the blood red in front of Qiao Qian's eyes gradually faded, and the puppet in the painting returned to normal.

"How many of you painted something?"

The boss is a man with shoulder-length hair, who walked out of the back room on a pair of flip-flops, and came out with his eyes still glued to the screen of his phone.

"Boss, these paintings of you...."

Deng Ming hadn't finished speaking, and the boss replied without raising his head,

"These paintings are not for sale, but are collected by our store. You can look at the painting tools. "The owner of the painting shop is not very enthusiastic about business, and his spirit seems to be a little decadent.

"Has anyone come to you lately and bought a lot of painting materials?" Xing Yi asked straightforwardly.

"This.... There are more people who come to buy it, how do I remember it? The boss replied nonchalantly, his eyes still looking at his phone.

"Of course you can't remember if you buy less, but if you buy more, you will definitely have an impression." Xing Yi took out his police ID card and put it on the table, "Please cooperate." ”

The shopkeeper glanced at the documents, and when he saw the word criminal investigation, a surprise flashed in his eyes, he swallowed his saliva, and finally put down his mobile phone.

"I want to think about it.," he rolled his eyes seriously, and said slowly, "It's true that two people have bought a lot of things. ”

"What kind of two people?"

"Business in my store has been sluggish, but they really buy a lot. Half a month ago, there was a woman with a hat and a mask, 25 years old, very thin and tall, with long hair. There was a strong smell of cheap perfume on my body,"

"Two weeks ago a young man came to buy it, and he was very thin and tall, wearing a hoodie and a black wide-brimmed hat, and he felt very sloppy and unkempt."

"Do you have surveillance in this store?" Deng Ming then asked.

"There's one at the door, I can export it." The boss pointed out.

"I'll go with you." Deng Ming took out the USB flash drive and followed the boss into the inner room.

"So our murderers, two .....?" Yu Meng was a little stunned.

"At the moment, he can only be considered a suspect." Qiao Qianwen said lightly, her eyes unconsciously glanced at the portrait of the puppet on the wall, and her heart twitched tightly.

The lower left corner of the portrait is marked with the word "W.j" in bright red color.

"W.j...."A trace of doubt flashed through Qiao Qian's mind, and she took out the rose picture she had just bought from the paper bag, and the lower left corner of the picture was also marked with the same signature in blood red.

Xing Yi hung up the phone and said to everyone, "Let's get ready to go back to the bureau, Yang Yi has found out the news." ”

"Thank you for your cooperation, and if you have any news, please remember to contact us."

"Okay." The shopkeeper nodded busily.

"Slow down, you guys."

When the group and two cars drove out of the parking lot, a light rain was already falling in the sky.

Deng Ming's black Land Rover drove in front of their coupe, and as the rain began to fall, their speed became slower and slower. Turn left at another traffic light and you will see the Criminal Investigation Bureau building.

Xing Yi glanced at Qiao on his side, who had not been quite right from the beginning.

"Now you can tell me about it."

A look of surprise flashed in Qiao Qian's eyes, and she looked at him sideways.

"Say what?"

"About the painting that just made you disarmed."

“.... It's nothing. ”

"You know it's useless to try to hide it from me."

Xing Yi thought that this little woman would fight with him again, but she was just silent for a while, withdrew her eyes and looked out the window, and said quietly,

"Every painting is alluding to the scene of a homicide, isn't it..... And that doll is a picture of the death of my high school friend..."

He was slightly stunned, others didn't notice, but he obviously felt a slight tremor mixed with her indifferent words. She was scared.

If it weren't for her, Xia Chu really wouldn't have died.

Qiao Qianwen forced herself to stop thinking and closed her eyelids a little tiredly.

"If there's something you can't solve, come talk to me. Always welcome. ”

"I'm not a criminal." She opened her eyes slightly and closed them again, "And you're just an expert in criminal psychology." ”

He chuckled, "Who told you that I only studied criminal minds." ”

"Forget it, you're useless to my dying heart." Qiao Qianwen opened her eyes, "Living things, you are better than me, dead things, I am better than you." ”

Xing Yi only raised his eyebrows slightly and said nothing more.

"Okay, then you go to the forensic office first, I have to go to the director's place."

-----

Forensic Doctor's Office.

As soon as she returned to the forensic office, she immediately put on a white coat and gloves and a mask, and entered the deplaning room.

She first opened Shen Hong's corpse cabinet.

Regarding the results of the autopsy, she knew that there would be no mistake, but she did ignore one point, which was something that the previous murderer had not had.

She searched through the corpse for any subtle and unnoticeable parts, and finally found a tiny mark between Shen Hong's toes and thumbs.

Sure enough, it was W.J. again.

There was a crisp knocking sound, Qiao Qianwen looked sideways, and through the long glass of the unplaning room, Xing someone, who had changed into a police uniform, was looking at her. There was also Deng Ming standing next to him with a smile on his face.

"Sister Qiao asked me to test this painting." Yu Meng carefully placed the painting on the table, "The paint for this painting is indeed human blood." And the blood type just happened to match one of our corpses here. ”

"By the way? That's just a coincidence of the same as some TV dramas. Deng Ming was a little unconvinced.

"And yet, it's such a coincidence." Yu Meng glanced at him helplessly, "The pigment is RH-negative AB blood, and Shen Hong happens to be of this blood type." ”

"When Sister Qiao was inspecting Shen Hong's body, she found that there were several recovering pinholes in the crook of her arm." Yu Meng added.

"Pinhole...."Deng Ming shuddered, "I thought she was taking drugs, it turned out that she was drawing blood to make paint!" Bloody enough .... offended a pervert, and she ended up too miserable. ”

"By the way, Dr. Joe." Xing Yi suddenly turned his words to her, "Just now you went to learn about the planing room again, looking at your appearance, did you find something?" ”

I can't hide anything from him... Qiao Qianwen raised her eyebrows slightly, reached into her pocket, and handed them the pictures she had just printed out from the computer one by one, explaining them in passing.

"Dr. Joe, you mean that the murderer made a secret mark on the body?" Deng Ming frowned and looked at the photo in his hand.

"Yes." Qiao Qianwen looked at a few people and was very sure. "This is a picture that was just taken, and there is one for each body. And it's all between the thumbs of the left foot. ”

"W.J...."Xing Yi looked at the mark and curled his lips slightly, "Do you think it's strange?" ”

"It's quite strange...."Deng Ming and Yu Meng looked up at him at the same time, and said in unison, "What's strange?" ”

He smiled and looked at Qiao Qianwen, "Such an arrogant murderer who loves to show his works, but engraved his signature in such a secret place, for fear of being discovered.... Isn't it strange? ”

"Hmm... Another thing that is also very strange is the signature. Qiao Qianwen continued, "I re-flipped through the dissection report that the teacher had written before, and there was no record of w.j engraved on the corpse at all. That is to say...."

"In other words, this murderer has committed crimes again after many years, but he has some strange habits." Xing Yi continued.

"But, I wonder, could it be that he changed his modus operandi?"

Xing Yi looked at her and shook his head slightly.

"Such a well-planned murderer would not risk changing his modus operandi. He is not stupid, leaving his signature is equivalent to one more risk factor for us to find him. ”

"Team Xing." Yang Yi pushed the door in his black briefcase.

"Well, you're just in the right place." Xing Yi nodded slightly.

"Brother Yi!" Deng Ming stepped forward excitedly, unable to suppress his curiosity and asked, "Brother Yi, what did you find?" ”
