Follow-up support soon arrived, although he was curious about the scene of the corpse, but because of his inconvenience, Zhu Jiangjiang still chose to wait obediently by the side, and returned to the public security bureau with the police car that completed the evidence collection first.

After Shi Chong, who returned to the police station, arranged the investigation, he did not immediately interrogate the owner of the V40, but slipped out of Zhu Jiang Jiangti, who was nesting in the mortuary, as soon as possible.

"Tell me, how did you get to the second street of building materials?"

Shi Chong crossed his arms and leaned on the office chair, although his expression was relaxed and casual, Zhu Jiangjiang would not really treat him as a little sheep.

"I researched the location of his body before and assumed that the places where the body was dumped did not overlap. Qinglong City is so big, except for the previous six points, if the murderer still commits crimes in the next few days, I calculate that it is most likely to be this area. Zhu Jiangjiang drew a circle on the map.

"In this area, there is less flow of people and less surveillance, and it meets his aesthetic standards, so I thought of Building Materials Second Street. So I asked Lan Bo to install a small program for me, but I didn't expect ......" Although Zhu Jiangjiang was calm on the surface, he was actually panicked.

The drama spirit had nothing to say in the end, so he simply spread his hands and let Shi Chong make up for his own brain.

"I didn't expect you to learn probability and criminal psychology so well, you guessed it right at a glance, it seems that it will inevitably trouble you to solve big cases in the future."

Shi Chong glanced at Zhu Jiangjiang with a smile, and he didn't know whether he believed her words.

"Okay." Zhu Jiang Jiang smiled sweetly back cheekily.

Just as the atmosphere was a little frozen, there was a knock on the office door.

"Captain, the suspect's information is here. The suspect's gloves, apart from bleach and alcohol, only have his own DNA. A hot beauty walked in, it was the only police flower in the team, Wang Xiaofeng, nicknamed "Queen Bee".

"Uncle Da and they searched the suspect's vehicle and found a black plastic bag on it, which was extracted after 502 and found that there were traces such as the footprints of the victim Lu Annie, which should have been used to package and transport the victim." Queen Bee reported the progress of the case to Shi Chong.

"Samples of Lu Annie's hair and fingerprints were collected in the V40 compartment, which is enough to prove that Lu Annie should have been in the suspect's car before she was killed. At the same time, there is also a mobile phone signal blocker in the car, which may be related to the disappearance of the victim's mobile phone signal. ”

"There was only a sample of Anne Lou's hair in the car? Did the other six victims compare? Shi Chong's hand flipping through the file paused.

"No, we have compared the rest of the hair samples with the six victims one by one, and there is no match for the time being, let's re-examine it carefully." The queen bee shook her head.

"He bought the V40 two years ago, and the place where he dumped his body was far away from his residential address, he had to have his own car and find a way to find the transportation he used before."

The current situation is very bad for them -

After Shi Chong realized that the murderer liked to appreciate his masterpiece, he asked Lan Bo to search all the surveillance near the dumping site, but only found something from the surveillance near the dumping site of the first deceased and Wang Manli;

The residual DNA sample from the first deceased matched the suspect;

There is also this evidence that Lu Annie left in the car.

Other than that, there is nothing else.

Because the suspect likes to use a mobile phone signal blocker, his own mobile phone and the GPS positioning of the V40 are not accurate, and the trajectory of his movements cannot be used as evidence.

A conviction in court cannot be based on conjecture alone, and it is too difficult to link the suspect to seven cases based on such a little evidence.

Now we can only hope that the suspect will take the initiative to confess to the case, or Lin Zihan's team will find more evidence at the suspect's home.

"Let's go, we'll meet him." Shi Chong grinned.

"We?"

said that it was us, but in fact it was Shi Chong and another member of the criminal investigation team who went in, and Zhu Jiangjiang just stayed in the corridor of the interrogation room to watch the interrogation.

The "White Lover" killer, whose full name is Bai Qing, is a nurse working in the People's Hospital.

Being a nurse gives him access to short-acting anesthetics and sleeping pills, and his amateur orders create more opportunities for him to come into contact with victims.

Except for Wang Manli's case, the other six cases occurred in the days when he was resting at home, and there was no alibi.

On the day of Wang Manli's crime, it happened to be his time to get off work, and the community surveillance filmed him driving out that night.

But I don't know if they are sure that they can't find more evidence, and in the face of Shi Chong's aggressive questioning, Bai Qing behaved very calmly and did not enter the oil and salt.

"If, I mean, if you are the murderer, why bother to cut the victim's wrists repeatedly instead of killing the victim directly, which is more time-saving?" Shi Chong asked a different question.

"Do you know how amazing the feeling of a pulse can be?" Bai Qing raised his handcuffed hands and kissed his wrists with a look of fascination.

"You don't know. I once saw a woman who slashed her hand so simply that the filthy blood kept pouring down the ground and her little child was watching. ”

"Obviously, she betrayed her family first, but she didn't suffer the pain, she walked away with a smile."

A sarcastic expression flashed on Bai Qing's face, and he was obviously smiling but acting extremely cold.

"How good do you think it feels to cut the veins? Shouldn't those who are terminally ill be grateful to the murderer for allowing them to be easily delivered? ”

"You're saying they're all sick? Do you think they all deserve it, and that dying is liberation? Shi Chong asked in a low voice.

"Who's to say it isn't?" Bai Qing smiled, his fingers slid over the faces of the victims lined up on the table, and his hands couldn't help but pause as he passed Wang Manli.

"It's a pity that sometimes in life, there are inevitably some imperfections."

Zhu Jiangjiang seemed to have thought of something, and did not continue to watch the interrogation, she had a bold idea that urgently needed to be verified.

"Master, the sixth victim of the 'White Lover' case, is her body still there?"

"Yes, it should have been taken away yesterday, but the victim's family has not appeared."

Seeing that she was anxious, Yang Bolin didn't ask anything, and motioned to Dalong to help her pull out the body she wanted to use.

Zhu Jiangjiang put on gloves, sprayed the chromogen evenly on Wang Manli's wrist, and then illuminated it with a green light, but found nothing.

Undying, she changed her hand again, this time it was the scarred hand-

Under the green light, a broken lip line appeared on the edge of the staggered wound!

"Found it!"

Zhu Jiangjiang was so excited that he hurriedly raised his full-spectrum camera to take a picture.

The same method was concocted and verified on Lu Annie's body, but not surprisingly, there were no marks on Lu Annie's wrists.
