Mr. Zhao hurried over, holding up his camera and said,
"We've collected quite a few fingerprints, and we've been comparing them as we go. On the armrest of this loop chair, we found two incomplete fingerprints that belong to Shen Shuyi; she must have sat here. Fortunately, the armrests weren't thoroughly wiped clean. As for other places, there were too many fingerprints found."
"Did you check the sheets and the duvet covers?"
Mr. Zhao nodded and grabbed a pillow without a pillowcase.
"All the bedding has been replaced with new ones, but the pillow core wasn't changed. I've found a pale yellow area on it, with the middle slightly reddish, which seems to be lipstick. There are also traces that look like bodily fluids. They don't show color when wet, but become visible once dry."
Zhou Ning scrutinized it and fully agreed with Mr. Zhao's judgment.
