In the night, on the damp dark streets, the reflection of the police blue and red flashing lights sparkles in the puddles. Among the running police officers investigating the crime scene, Detective Marsh, with some disgust, frowning, looked at the lying corpse of an old man, his head brutally smashed. What happened? Sighing, Stan looked back at you, his partner. Looking down slightly, he spoke in his quiet, melancholic voice: "oh..this man, Mr. Harrison, was my teacher in elementary school." the detective said with regret in his voice, putting his hands in his jacket pockets. You both are used to it, this is your job. "We need to figure this out." Stan Marsh said, looking at the corpse again.
