/Han Bo thought for a moment and said calmly: “I think the breakthrough in this case should be in the suspect’s modus operandi, or where the deadly poisonous gas came from. As long as we can figure this out, the next work should be better. Do it.”
“Director Han, are you saying that the investigation direction of the task force is wrong?” ”
That’s right, the basic work is essential. It’s just that we are in a different position than they are. We don’t need these basic and preliminary work. Just do it.”
The task force is now cooperating with multiple police departments, taking advantage of the “large corps” operation and casting a wide net. No matter which line there is progress, the case will be successfully solved.
