Upon hearing this, Jiang An felt a sense of joy in his heart.
Regarding this case, he firmly believed that the deceased did not put up fierce resistance and left no traces of struggle.
A very important reason for this is that the perpetrator might have carried a threatening weapon.
And this threatening weapon is most likely a firearm.
The deterrent power of a firearm is far greater than that of a knife or a person's presence.
Immediately, Jiang An said in a deep voice, "Officer, please continue investigating along this line of thinking."
"Try to find out if anyone was selling firearms three years ago."
On the other end of the phone, Zhang Chao quickly said, "Okay, Mr. Jiang, no problem!"
"I will give you feedback at the first instance we receive any information."
Zhang Chao also felt regretful about this case.
Moreover, this time the deputy leader of the special task force is Jiang An.
He naturally put down his authoritative posture.
