Detective John Smith stepped out of his car onto pavement. Frosty morning air cut through his coat, biting sharply. The dimly lit alley reeked of garbage and urine. Yellow crime scene tape fluttered in the wind gently. A body lay crumpled against the brick wall lifeless. Blood pooled around its head, a deep crimson hue. John knelt down, examining the body carefully. Multiple stab wounds covered its chest and stomach area. The victim was a middle-aged man in a suit. His eyes stared blankly, frozen in a look shock. John stood up, turning to his partner slowly. "Looks like we've got another one," he said quietly.
