"But back then we didn't find any obvious signs of rummaging."
The two looked at each other, a heavy understanding lingering in the air.
After a moment, Jiang An replied, "Is it possible that the item the killer was looking for was very unique, and they didn't need to turn everything over to find it, but could recognize it at a glance?"
This speculation made Li Jian's eyes light up, and he immediately plunged into deeper thought.
At the same time, at the Jiangcheng City Forensic Identification Center, bloodstain analysis was underway.
Senior examiner Li Ming was carefully extracting an old bloodstain sample with a cotton swab.
His movements were precise and gentle, as he feared damaging any potential evidence.
The assistant beside him frowned at the sample, "Mr. Li, this bloodstain is so old. Can we still get effective results?"
Li Ming's lips curled into a confident smile.
"Maybe not last year, but definitely this year."
