Chapter 1137 - 1068: Internal Investigation and External Coordination
If it were someone else insisting on this, Cao Chujun would have argued back a couple of lines. But since it’s Jiang Yuan, Cao Chujun couldn’t help but take it more seriously.
"I’ve checked all domestic archives I could access—there’s no such person. Additionally, I asked several connections to inquire about it, but there’s been no reply so far. It seems like there really isn’t anyone by that name." Yu Wenshu, having been pulled along by Cao Chujun to run some circles, returned and met with Jiang Yuan.
Jiang Yuan rubbed the Guan Gong emblem on his chest, nodded slightly, and said, "No rush. Keep investigating for now. Since we don’t have a second suspect yet, this Lu Jianchun is still highly suspicious."
"This suspect, Lu Jianchun, indeed has some issues. A regular person wouldn’t behave like this during interrogation. Even if he isn’t the murderer in this case, he’s probably carrying baggage from another crime." Cao Chujun, a veteran detective, knew this very well. Back in his younger days, solving major cases depended heavily on interrogation. Unlike now, when detectives can immediately retrieve deleted messages from suspects’ phones.
Everyone nodded in agreement. After two days of questioning, their morale remained relatively stable largely because of this.
If they’d encountered someone innocent, terrified, or overly cooperative—divulging everything with no resistance—the case might’ve been even more troublesome.
Although Lu Jianchun had been involved with the first victim, Zhao Qian, such relationships aren’t illegal. Furthermore, Zhao Qian had many targets, and Lu Jianchun ranked favorably amongst them in terms of appearance. Falling within her radar and getting entangled was quite ordinary.
"We could enhance our visits to Lu Jianchun’s ex-wife, relatives, as well as his friends. If necessary, bring them in for questioning." Liu Jinghui suggested a straightforward method.
Yu Wenshu immediately replied, "Sure, that works."
If a suspect is difficult to crack, then focus on breaking through the people around them. There’s no such thing as a truly solitary individual; humans are the sum of all relationships. Establishing interpersonal connections is a basic human need, and it’s hard for someone entirely isolated to survive in society.
