Before long, Jiang An led the entire team, equipped with professional investigation tools, into the room once more.
Standing at the entrance of the living room, Li Jian asked, "Brother Jiang An, in your opinion, where should we focus our investigation this time?"
Jiang An raised his head, his gaze slowly scanned the surroundings, finally fixing on the floor before him.
"If carbon monoxide didn't enter the room in its gaseous form, then it's highly likely it existed in its original solid form. There might be a device that generates carbon monoxide inside the room."
"Therefore, I think it's necessary to start with trace evidence."
Li Jian listened and did not speak, just lightly nodded his head.
Regarding Jiang An's line of thinking, he found it somewhat reasonable.
However, the current investigation direction is based on the cause of death being carbon monoxide poisoning.
If the cause of death is alcohol poisoning, then all the current efforts may be in vain.
