A sea of luminescent blue light met their eyes. Everyone's exposed skin was bathed in a ghastly blue glow, appearing both deep and eerily unsettling.
"What on earth happened here?" The sole female forensic officer swallowed. "Did the killer actually use blood as water to mop the floor?"
It was a scene of a scale rarely witnessed. Even these experienced forensic officers were momentarily stunned.
Dean, however, showed little reaction. After scanning the area, he looked puzzled. "These marks do look like they were made by a mop, but if so, what was the perpetrator's purpose?"
Bloodstains were hard enough to clean completely; spreading them everywhere would only make it more troublesome, wouldn't it?
