In the evening, the crime scene was still closed, but there were far fewer people at the scene than in the afternoon.
The injured, firefighters, and medical staff all left, leaving only the police officers from the city bureau at the scene.
Li Jie, Duan Yingjiu, and Li Shiqing were also taken away from the scene long ago.
At this time, Li Jie and Li Shiqing were already in the inquiry room of the Municipal Bureau.
An hour ago, the first round of questioning ended.
Looking at the empty inquiry room, Li Shiqing couldn't help but feel a little scared.
At the same time, her heart was filled with self-blame and regret.
After all, she couldn't stop Officer Zhang from questioning, and she told him about the cycle.
'How's it going with Professor?'
Li Shiqing glanced in the direction of the door, with a hint of worry in her expression.
On the other side, in the monitoring room, Zhang Cheng was sitting in front of the monitor, carefully observing the situation in the interrogation room.
Sitting next to him was a middle-aged woman, the director of the Xiazhou City Public Security Bureau.
"Du Bureau, what do you think of Li Shiqing's confession?"
Director Du flipped through the confession at random, then closed it with a snap.
"Prepare to give her a drug test."
As soon as these words came out, Du Ju's meaning became obvious.
What cycle?
Isn't this nonsense?
Such a confession made her wonder whether Li Shiqing was taking drugs.
"By the way, give Li Tang a drug test too."
As she spoke, she paused slightly, glanced at Li Jie on the screen, and then added.
"Don't ask Xiao Jiang to inquire later. Let's go to another brother instead."
"good."
Zhang Cheng hesitated for a moment, and he understood what Du Bureau meant. After all, 'Li Tang' was not an ordinary person, and given his identity and status, he had no motive to create an explosion.
Not only that, the other party also provided them with very crucial clues.
Half an hour ago, the police had identified the suspect in the explosion. The suspect was the woman who got on the bus from Gangwu New Village.
Tao Yinghong!
In the room rented by Tao Yinghong, the police found a large number of chemical experiment equipment, and during subsequent testing, they found residual traces of explosives.
"Du Bureau, the composition of the explosives at the scene has been analyzed."
Talking about Cao Cao, when Cao Cao arrived, he was still talking about Jiang Feng on the front foot, and he arrived on the back foot, and with him came a report from the scene.
"Bring it here."
Director Du raised his hand, took the document and began to read it.
Zhang Cheng, who was on the side, saw something strange in his apprentice's expression, and then he asked directly.
"What's wrong?"
Jiang Feng scratched his head and said with confusion: "Master, this report is slightly different from what we expected."
"The main component of the explosive residue we found in Tao Yinghong's home was ammonium nitrate, but the main component of the explosive residue left at the scene was trinitrotoluene, also known as TNT."
"In addition, we visited the unit where Tao Yinghong worked and found that the only chemical raw materials Tao Yinghong had access to were ammonium nitrate."
"This is consistent with the evidence we found at her home."
Zhang Cheng frowned when he heard this, his expression full of surprise.
What is going on?
Tao Yinghong made ammonium nitrate explosives, but the explosive at the scene was TNT.
Where do these TNT explosives come from?
On the other side, Director Du's brows also tightened. Originally, according to the clues provided by 'Li Tang', they were almost on the verge of solving the case.
But as soon as this report came out, the case became confusing again.
If the chain of evidence cannot be closed, the case cannot be closed!
The most critical thing is that the important suspect in this case, Tao Yinghong, has died in the explosion, and they cannot interrogate the suspect at all.
After thinking for a moment, Du Ju opened his mouth and gave instructions.
"In this case, Lao Zhang, you and your brothers will continue to follow Tao Yinghong's clues. First, we need to figure out her motive for committing the crime."
"Secondly, the matter of explosives must be clarified. With Tao Yinghong's channels, she should not have access to the raw materials of TNT."
"The source of TNT must be thoroughly investigated!"
"Also, don't forget about the drug test. Do it now."
"Yes, I'll go right away."
As soon as he finished speaking, Zhang Cheng quickly stood up and led his apprentice out of the monitoring room.
Tonight, they are destined to stay up all night.
At the same time, Duan Yingjiu, who was in the reception room, also had a doubt in his heart.
Her application for assistance in the investigation was approved, and now she has access to the latest developments in the case.
According to the city bureau's investigation, Tao Yinghong is indeed highly suspicious.
In addition, as 'Li Tang' expected, the driver also had problems. Wang Xingde and Tao Yinghong were husband and wife.
Combined with what 'Li Tang' observed, Wang Xingde probably knew about the explosion in advance.
Now, Duan Yingjiu just wants to figure out one thing.
Was the explosion aimed at 'Li Tang'?
If not, ‘Li Tang’ would have suffered a terrible disaster.
If so, then the problem is serious, which means that the identity of 'Li Tang' is likely to be completely exposed.
Although 'Li Tang' has a good relationship with the current director of the Military Intelligence Bureau, Sun Chuanwu has reached the age of retirement.
According to the intelligence sent back from across the sea, Sun Chuanwu is now almost in a state of semi-retirement.
At the same time, the appointment results of the next director have also come out.
The new director is a ruthless character with an extremely tough behavior and basically zero tolerance for traitors.
If he knew about the rebellion of 'Li Tang', the bombing was probably the work of the other party.
While he was deep in thought, Duan Yingjiu's cell phone suddenly rang.
When she lowered her head, she saw that the caller was her immediate boss, Wang Yang.
"Old Duan, how is the situation?"
Wang Yang's current position is deputy director. The reason why he was promoted so quickly has something to do with Duan Yingjiu. To be precise, his rapid promotion has a lot to do with Li Jie.
Without the information provided by 'Phoenix', he would never have risen so quickly.
Therefore, he is very concerned about this case.
"Things are a little bit not good."
Although there is no evidence yet, Duan Yingjiu still feels that the bombing was aimed at the Phoenix.
The bus was full of passengers, and apart from Phoenix, there was no one special.
In addition, according to the last surveillance footage of the bus, the bomb exploded not long after Phoenix got off the bus.
The timing of the explosion was too coincidental.
"Wang Ju, is there any movement on the other side of the sea?"
"Not yet, it's still calm over there."
"No?"
After getting this answer, Duan Yingjiu's doubts became more and more intense.
No movement at all?
This was completely different from what she expected.
Could it be that the bombing was not done by people from across the sea?
If not, where did Tao Yinghong get the TNT?
Who did this case?
This question not only troubled Duan Yingjiu, but also troubled Zhang Cheng and Du Ju. Li Jie was also puzzled.
