When Shen Liqing asked Su Yan if he suspected that the murderer was from Yun Province, Su Yan nodded: "It's possible. After all, April 13th is such a coincidence."
No one at the scene refuted this. According to Su Yan's explanation, this is indeed possible.
"The murderer last killed the jewelry store owner on April 11th. If the murderer went home to celebrate the Songkran Festival, he should have left that day or the next day, otherwise he would not have made the trip."
"We only need to investigate people who took transportation to Yunnan Province on April 11th and 12th, and then screen them one by one."
Su Yan revealed the crucial point in his judgment, how to find the murderer!
After listening to Su Yan's explanation and conclusion, everyone was shocked.
If Su Yan's analysis is correct, it will not be difficult to find the murderer.
"Zhao Da, you immediately send people to major transportation stations to investigate the people who left Jiangning City on April 11th and 12th to see if any of them went to Yun Province?"
Shen Liqing looked quite excited. Although Su Yan was just inferring everything, it was completely reasonable. By investigating major traffic points, it was possible to find clues to the murderer.
Zhao Yang was also very excited. Without saying a word, he immediately arranged for people to go to the airport, train station and long-distance bus station to investigate.
In order to avoid any omissions, he also sent people to major taxi companies and car rental shops to catch this murderer in one fell swoop.
After Su Yan finished his analysis, Wu Yaqin's cousin, the big fat man, looked at Su Yan blankly, with a look of disbelief on his face.
Is that human being? But just because the murderer answered the phone and the other party asked a casual question, can we deduce the murderer's whereabouts? !
This is simply amazing!
The big fat man couldn't help but shake his head. It was true that he fell into the opponent's hands unjustly. Even if he didn't catch him now, he would fall sooner or later.
On that day, all members of the criminal police team were dispatched to various traffic points to search for the whereabouts of the murderer.
In order to cooperate with the criminal police team, the city bureau director Dai Raofeng personally mobilized all major police forces to go to various places to investigate.
This investigation can be said to have opened a huge fishing net. No matter how cunning the murderer is, he will never be able to escape.
Sure enough, in the afternoon of the investigation, news came from the high-speed rail station. In the early morning of April 12, a man took the high-speed rail to Yun Province. The man's physical characteristics were very similar to the murderer.
When Su Yan and others heard this, they immediately rushed to the high-speed rail station to check the surveillance video in person.
Several police comrades in charge of security at the high-speed rail station immediately took Su Yan and his party to the monitoring room after they arrived.
The staff at the high-speed rail station quickly advanced the surveillance video to the time when the suspected target appeared.
The surveillance video is a bit blurry, but by comparing it with the images described by Wu Yaqin's cousin, his figure and age are very consistent.
The suspected target in the video was only carrying a satchel and nothing else.
"Is it the murderer?" Everyone looked at the surveillance video, and for a moment they were not sure that this person was the murderer.
Su Yan took the information of the man in the surveillance video. According to the information, the man's name was Tang Youming, a native of Yun Province, and he was 36 years old.
The information currently known is only obtained from the person who registered and purchased tickets using his identity verification name, and there is no other information.
"Check when did Tang Youming come to Jiangning City? If he also took the high-speed rail when he came, we should be able to find out." Su Yan turned to a staff member at the high-speed rail station and said.
The staff at the high-speed rail station nodded, searched by name, and finally discovered that Tang Youming came to Jiangning City three months ago and indeed took the high-speed rail.
And the time he came was surprisingly the day before the first victim, Xiang Zhong, was killed.
"The time is right!" When everyone saw it, they couldn't help but be happy.
Su Yan frowned at this time.
"Although the time is right, why did he, a native of Yun Province, come all the way to this unfamiliar Jiangning City to kill and rob?"
Su Yan asked a question.
Everyone didn't know the answer to this question and couldn't help but shake their heads.
Su Yan's eyebrows furrowed tighter and tighter, and he suddenly raised them. He pointed at the man in the video and said, "Bureau Shen, if this person is the murderer, I suspect he has accomplices in Jiangning City."
Shen Liqing and others followed the direction of Su Yan's finger and after thinking for a moment, they were all shocked.
The picture Su Yan pointed to was clearly the satchel carried by the suspected target.
The suspected target only left with a satchel, so where did he put the large amount of gold and silver jewelry he robbed?
He couldn't get rid of it in a short time.
Considering the reason why he came all the way to Jiangning City to kill and rob, it can be concluded that he has accomplices in Jiangning City.
Shen Liqing stood up and said to Zhao Yang and others: "According to Xiao Su's judgment, we have to do these things now..."
Zhao Yang and others immediately listened carefully.
"First, let the provincial department contact the police department where Tang Youming works to investigate him. If necessary, we will go to Yun Province in person."
"Second, secretly investigate the entire Jiangning City and surrounding cities and counties to see if anyone has recently sold the stolen gold and silver jewelry and jewelry?"
"Third, check all hotels in Jiangning City to see if Tang Youming has stayed there before."
Shen Liqing issued three orders in a row.
Zhao Yang was about to send people to carry out the execution one by one, when Su Yan added: "We also need to check Tang Youming's bank account to see if there have been any large funds transactions recently. If so, find out whether it is an account!"
Shen Liqing was very satisfied with Su Yan's addition and immediately nodded to Zhao Yang to execute it.
…
After Su Yan and others returned to the criminal police team, several orders quickly received feedback.
According to the investigation by colleagues from Yun Province, Tang Youming did come back during the Water Splashing Festival, but now he has left home again and his whereabouts are unknown.
As for the issue of selling stolen goods, the results obtained through informants and investigations show that no one in Jiangning City and neighboring cities and counties privately trades large amounts of gold and silver jewelry and jewelry.
There have been no large funds transactions in Tang Youming's account recently.
In addition, when he came to Jiangning City three months ago, he disappeared like a mud cow into the sea, and there was no record of staying in a hotel.
Facing the feedback one after another, all the investigators frowned.
These messages all show that Tang Youming seems to have a problem, but there is no substantial evidence.
"Damn, this guy is so cunning!" Lu Jiao punched the conference table and cursed.
Shen Liqing and others nodded. If this Tang Youming was the murderer, he was indeed cunning and treacherous.
"The most important thing is that he is missing now. Otherwise, if he is brought back for interrogation, we might be able to find out some clues!"
Zhao Yang extinguished half of the cigarette in his hand and said.
Su Yan flipped through the feedback information in his hand and did not participate in the speech.
"Xiao Su, what do you think of the current situation?" Zhao Yang took out another cigarette and lit it. When he found that Su Yan had not spoken, he asked.
Su Yan didn't answer. He put down the information in his hand and looked up at the ceiling.
When Zhao Yang and others saw it, they felt strange and were about to continue asking.
Su Yan suddenly lowered his head, looked at Shen Liqing and Zhao Yang with piercing eyes and said: "Shen Bureau Zhao Da, Tang Youming is very likely to come to Jiangning City again!"
"Ah!" When everyone heard this, they were all shocked.
