Yu Chihong looked around in shock, was the person who put the bomb vest on Jing Junbai also at the scene? But the crowd was mixed, and there was no clue at all.

Jing Junbai had already fallen into a state of madness, and he wanted to dismantle the bomb vest by himself, but this move immediately detonated the bomb, and the flames rolled in, forcing Yu Chihong to roll on the ground and dodge in time.

Before Jing Junbai could scream and scream, he had already turned into a fireball and fell to the ground, and the raging fire instantly devoured his upper body and burned it into charcoal.

Qiao Yan witnessed this terrifying process and stood in place, horrified. Yu Chihong got up from the ground, and there were screams of horror all around, but fortunately, the power of the explosives was not great, and it only killed Jing Junbai and did not hurt anyone else.

"I saw with my own eyes that the deceased was wearing a bomb vest under his blazer. The vest was equipped with a liquid bomb and a timing device on it. Wei Chihong recalled the terrifying scene, and was still annoyed in his chest, and he watched the victim die in front of him, but he couldn't save him.

Cao Chongshan's test results showed that the vest contained a mixture of nitrobenzene and potassium cyanate, and once the vest was forcibly removed, the mixture would explode through friction. In other words, it is a "death vest" that cannot be taken off once it is put on. He coughed violently as he spoke.

"Are you sick?" Wei Chihong looked at Cao Chongshan carefully, he was already too thin to look like a man.

"It's nothing, it's just ......," he coughed a few more times before he said, "I have a cold...... I don't know how the bomb was defused, but the prisoner must have been a very skilled person, and I think it was probably a researcher at the university. ”

"You'd better rest at home for a few days." Wei Chihong couldn't look at it, "I'll give you a few days off and come back after you get your body well." ”

Cao Chongshan coughed, but waved his hand again and again. "No, I can handle it. When I go home, there is no one to take care of me, so it is better to be here, and there are apprentices to help buy medicine. ”

Yu Chihong patted him on the shoulder, speechless.

"There's one more discovery." Cao Chongshan took an evidence bag containing a ruby, "which was found in the trouser pocket of the deceased." ”

"Is this ruby real or fake?" Yu Chihong asked.

Cao Chongshan said that it has not been identified, and it is not clear.

Wei Chihong's heart moved. "I'll figure this out myself to lighten your workload."

Yu Chihong took the ruby to the city's famous Changsheng jewelry store that Susie robbed and asked a technician to help identify it. While the technician was working, he walked up to a jewelry brand counter and asked if he could order an Eiffel Tower-style diamond ring.

"What a coincidence you've come." The counter lady told Yu Chihong with a smile that the designer of this brand, Philippe Tournaire, happened to be from the romantic capital of Paris, and was a master jewelry designer, known as the leader of the vigorous development of the new concept of colorful jewelry design. Philippe's jewellery broke with tradition and he pioneered the idea of infusing architecture into jewellery design. Whether it is the castle in the heart of a lover, the cottage of dreams, or even a well-known monument, it can be expressed by him in a stunning miniature way, between the square inches of his fingertips. Therefore, there is absolutely no problem in customizing an Eiffel Tower diamond ring, as long as you say the specific requirements, there will be a design team to create a beautiful, charming and unique diamond ring according to the requirements.

Wei Chihong said that he would draw the ring style in his mind into drawings, and then take it to the counter and hand it over to the designer team as a reference.

The identification of that ruby came out, it was a man-made synthetic gemstone, and it had no value. This made Yu Chihong quite puzzled, why did Jing Junbai bring an artificial ruby with him?

The criminal police investigating the murder of Jing Junbai reported that according to the testimony of his colleagues at the television station, Jing Junbai seemed to have received threatening phone calls before the incident. The criminal police found the content of the last call he recorded before he was killed from Jing Junbai's mobile phone:

"Please let me go!"

"No, do as I say! You don't pay much attention to your image, I'm just going to make you crazy, and your image will be ruined, ahahaha......"

"Spare me!"

"If you don't do it, I'll stop the timer, hurry up!"

……

The other person's voice is processed. checked the mobile phone number left in Jing Junbai's mobile phone, which was called from the mobile phone of the unknown owner, and the identity could not be confirmed. However, it was found that the mobile phone signal was sent from a base station antenna 300 meters away from the crime scene, and it was estimated that the call was made near the crime scene.

Wei Chihong asked Lu Xipeng to analyze the prisoner's voice. The vocal cords are the fingerprints of the voice, which can be analyzed even after voice change processing, and with only 10 to 20 words, professionals can determine the characteristics of the speaker with great precision. Lu Xipeng's analysis showed that the prisoner was male, between 1.68 and 1.71 meters tall and 45 to 55 years old.

But other than that, the people around Jing Junbai, including his fiancée Yang Yujie, couldn't provide any valuable information.

"Yang Yujie was quite calm about her fiancé's death." When he went to the office of the special investigation team to exchange information, Lu Bin said mockingly, "It is estimated that a lot of benefits have been reaped after the engagement, and the fiancé is dead, and you can find a richer one, and there is nothing to lose." ”

"You're too ruthless." Qiao Yan smiled, "Jing Junbai and Yang Yujie's engagement was originally like a show, and I can't see how much truth there is. The prisoner put on Jing Junbai's 'death vest' because he wanted him to experience great fear before dying, and there must be a deep hatred between the prisoner and Jing Junbai. ”

"Could it be related to Yin Xinyue's death?" Zeng Jinling guessed, "Yin Xinyue died because of Jing Junbai, although the murderer was not Jing Junbai, but he indirectly killed Yin Xinyue." But the law could not punish him, and he still lived freely. Maybe someone wants to avenge Yin Xinyue. ”

But Yin Xinyue's adoptive parents are too old and frail to do such a thing. She has no other relatives in the city. If it weren't for kinship, it shouldn't have come to the point of killing for her. Lu Bin disagreed, "Jing Junbai's kid is making peach blossoms everywhere, and he can't get into any love debts." ”

There is still too little information, and Qiao Yan and Zeng Jinling can't give specific portraits.

"Alas, it's been a bad year anyway." Lu Bin was helpless, "The day after tomorrow is Chinese New Year's Eve, that crazy guy, deliberately not letting everyone have a good New Year." ”

Then it was Chinese New Year's Eve, and Qiao Yan also sighed, this year, how many people around her can live well?

Yu Chihong was bent on tracking down the synthetic ruby, and Duan Zhiming and Lu Bin didn't understand why he valued the ruby so much. Maybe it was a professional sensitivity, or a gut instinct that led him to believe that the fake gem would be an important clue.

Yang Yujie said that she had never seen the ruby, and it should not be Jing Junbai's. Jing Junbai's colleagues have not seen this fake gem either, but the host Xiaoqing, who had interviewed Qiao Yan, provided valuable information - she had seen Yin Xinyue wearing a ruby ring on her hand, and the ruby on it was very similar to this one. Wei Chihong then found someone from Fire Dance Culture Communication Co., Ltd., whether it was Yin Xinyue's assistant Zhen Yuming, actor manager Wang Bingbing, or Yin Xinyue's best friend Ding Jia, all confirmed that Yin Xinyue had a ruby ring, Yin Xinyue had a soft spot for that ring, and wore it no matter what activities she attended, and the gem on the ring was almost exactly the same as the one on Yu Chihong's hand. Ding Jia also revealed that Yin Xinyue told her that the ruby ring was left to her by her biological mother, and when she was abandoned, the ruby was placed in her swaddling clothes, and the ring was an item that carried the memory of her biological mother, so Yin Xinyue cherished that ring very much since she was a child.

Yin Xinyue is dead, why did the ruby in her ring appear on Jing Junbai's body? Yin Xinyue's relics are with her adoptive parents, who came to attend the funeral and are still recuperating in the residence arranged for them by Huo Wu due to poor health, and will not return to their hometown until after the Spring Festival. After Yu Chihong approved Yin Xinyue's adoptive parents, he looked through Yin Xinyue's relics and found a ruby ring from it.

Wei Chihong took both gems back to the Forensic Science and Technology Laboratory and handed them to Lai Feng. In order to reduce Cao Chongshan's burden, Wei Chihong mainly entrusted the physical evidence examination work of this case to Lai Feng. After the plague fungus incident last time, he was impressed by this young man, and with his potential, he could become an excellent successor to Cao Chongshan.

"Would it be helpful to investigate something like this in the case?" Lai Feng looked at the two gems suspiciously.

Yu Chihong smiled slightly. "As long as there is action, there will be results. This is your master's famous saying, study hard. ”

Lai Feng nodded heavily, and hurriedly devoted himself to the identification work, and the appraisal result was that the two fake rubies were the same thing, and the color difference was only because they were contaminated.

On Chinese New Year's Eve, Qiao Yan had a simple Chinese New Year's Eve dinner with Zhuo Yiqin, Qiao Ran, and Aunt A Xiu, after which the four women sat around the stove and watched the CCTV Spring Festival Gala. Aunt A Xiu is the most attentive, and the others are not particularly interested in the Spring Festival Gala, while doing their own things. Zhuo Zhengqin continued to knit sweaters, and exchanged a few words with Aunt A Xiu about the content of the show from time to time. Qiao Yan traveled all over the world, Qiao Ran was busy chatting with Lu Bin on WeChat, and Lu Bin found all kinds of interesting New Year's jokes and sent them to Qiao Ran, just for the Pomeranian to smile. Lu Bin is a local, but he rarely has time to go home, and tonight is a rare reunion with his family. But he was at home, but his heart was here with Qiao Ran, chatting with his family without a word, and bowing his head to send WeChat to Qiao Ran.
