Detective Harris discovered the lifeless body in the abandoned warehouse beside the dark river at midnight tonight in the town. Bloodstains marked a trail from the rusty door to the corpse lying motionless beneath the broken windows above them somewhere. The victim was a young woman with platinum blonde hair and expensive jewelry still wrapped tightly around her pale neck. Strange symbols had been drawn on the concrete floor using what appeared to be the blood from her open wounds. Detective Harris pulled a small notebook from his trench coat pocket to record initial observations about this puzzling crime scene. The murdered woman carried no identification, but her manicured nails suggested wealth far beyond what most ordinary people could imagine. A strange scent lingered in the air mixing metal with lavender perfume and something else unusual Harris could not identify. Sergeant Wilson approached cautiously with his flashlight pointed toward the dark corners where shadows seemed to move with clear purpose. Someone had called police dispatch with an anonymous tip about screaming sounds coming from this building about three hours ago. The moonlight filtered through the cracked ceiling revealing strange symbols that formed patterns Harris recognized from his previous cult investigations. A single white feather rested on her chest as if placed there quite deliberately by someone who understood its meaning. Harris knelt beside the body noticing the peculiar angle of her neck suggesting death came from behind without any warning. The entire forensic team arrived shortly after midnight, carrying their silver cases filled with tools for gathering essential crime evidence. Lightning suddenly illuminated the dark night sky outside, creating a momentary brightness that revealed another shadow watching them from upstairs. Harris felt the familiar cold chill that always came with murder scenes, knowing this case would haunt him for years.
