The suitcase mentioned by Wang Dachuan that the man was pulling was quite small, approximately 20 inches in size.
Logically, it would be impossible to fit a person in such a small suitcase, even a five-year-old boy.
However, if it were under different circumstances, it might be possible.
Wang Dachuan deliberately avoided voicing his suspicions in front of the child's parents, mainly because he feared they wouldn't be able to handle it.
Besides, it was just his speculation, and he didn't want to frighten the couple before anything was confirmed.
However, even though he didn't say it in front of the couple, judging from Han Fei and Wang Dachuan's expressions, the parents could roughly guess what they had just discussed.
"Could my son be... gone?" The woman's face suddenly turned pale at that moment, her legs trembling uncontrollably.
Unable to accept such a possibility, she fainted in her husband's arms.
"Honey, honey, don't scare me!" The man quickly supported his wife, frantically patting her. "Officer, what's wrong with my wife?"
Xu Mo stepped forward and checked the woman's eyes.
"Your wife fainted from emotional distress. She should be fine... but I still recommend taking her to a nearby hospital for examination."
The man looked at his wife lying in his arms, then glanced towards the bathroom direction, feeling hesitant.
Xu Mo understood his thoughts and offered some comfort.
"Don't worry, we'll help you look for your son. You should take your wife to the hospital first, and we'll notify you immediately if we find anything... Just leave your phone number with me."
Even with Xu Mo's reassurance, the man still hesitated, concerned about both his wife's wellbeing and his son's whereabouts.
But after consideration, he realized that finding his son depended on the police, and staying here wouldn't help much - he might even get in the way.
After a brief internal struggle, he gave Xu Mo his phone number: "I'll take my wife to the hospital then. Officer, here's a photo of my son. His name is Wang Xiaoyu. Please contact me as soon as you have any news about him, okay?"
"Don't worry, we will."
After seeing Xu Mo nod, the man immediately carried his unconscious wife away.
After they left, the police officers also departed.
They planned to check the surveillance footage again to see where the man with the suitcase had gone after leaving.
According to Wang Dachuan's speculation, that suitcase might contain the child's body.
Under normal circumstances, such a small suitcase couldn't fit a five-year-old boy, but if the child had been killed, it might be possible.
The police had handled cases before where bodies were transported in suitcases.
In the surveillance room, with the mall manager's assistance, the officers reviewed the footage again.
The surveillance showed that after leaving the bathroom, the man with the suitcase headed straight out of the mall.
This behavior made him even more suspicious to the officers.
"Let's go back to the station and check the external surveillance cameras!" Han Fei said, getting ready to leave.
In the mall, they could only access internal cameras; external footage had to be accessed from the police station.
However, just as he stood up, Xu Mo pushed him back down.
"Time is crucial. Let's check it here. Why waste time going back?"
"Check it here? How can we..." Before finishing his sentence, Han Fei remembered that Xu Mo was a computer expert, a hacker. With a computer and internet connection, Xu Mo could hack into the surveillance system to check the footage, saving them the trip back to the station. Conveniently, the surveillance room had both.
"Alright, let's check here. How long will it take?" Han Fei asked.
By then, Xu Mo had already started working, not even turning his head as he replied, "Very quickly, just a few minutes."
Soon, Xu Mo successfully used the mall's surveillance room computer to hack into the system and access the external cameras.
The mall manager was amazed by this operation.
Impressive, are police officers this skilled nowadays? Just some quick typing and they could access external surveillance? Is this what they call a hacker?
He leaned forward, hoping to learn from Xu Mo's techniques.
However, as soon as he got close, other officers politely asked him to step aside.
With the help of surveillance footage, the police quickly tracked the suspect's movements.
The footage showed that after leaving the mall, he took a taxi to Yangcheng University.
After confirming the suspect's destination, Xu Mo also looked up the person's identity information to facilitate their search at the university. Then, the police left the mall and headed straight for Yangcheng University.
At Yangcheng University, several police cars drove through the entrance gate.
Seeing they were police vehicles, the security guards let them pass without stopping them.
Chen Ke's cousin was a student at this university, and he had dropped her off several times, so he was fairly familiar with the campus. With him there, the officers wouldn't have to search blindly around the vast campus.
"Turn left ahead. If I remember correctly, the administration building is this way."
Following Chen Ke's directions, they drove to the administration building. Although Xu Mo had briefly looked up the student's name and ID number before departing, these details alone weren't enough to easily locate someone on a university campus.
The quickest way to find someone at a university was to go to the administration building and have the staff help with the search.
