Zhou Ning quickly lifted the bag and walked under the LED light to take a close look, discovering that the blood fingerprint's pattern was unclear, resembling a droplet of blood.
No wonder Xu Guanhai didn't mention this blood print; he probably thought that a fingerprint without a discernible pattern wasn't worth collecting.
However, upon closer examination, the entire lower part of the fingerprint was horizontal with no vertical lines rising and falling, a discovery that brightened Zhou Ning's eyes.
Although the upper part was not visible, this was enough to prove that the owner of the fingerprint was very likely to have a bow-shaped pattern.
"I suspect that the killer has a bow-shaped pattern," he said.
Those around him all drew in a sharp breath and hurried over to look. Xia Momo and Mr. Qu glanced at each other, looking somewhat bewildered. Xia Momo turned to Zhou Ning and asked,
"Are people with bow-shaped patterns very unusual?"
Zhou Ning nodded.
