When A Killer Thinks He_s A Genius (but he_s an idiot)

A killer's arrogance is his greatest weakness. He thinks he's the smartest person in the room, but his own stupidity will be his undoing.He leaves his DNA on the knife sheath. He buys the murder weapon with his credit card. He texts a confession to his ex-girlfriend. He dumps a body with his phone's location tracking still on. These are the stories of killers who thought they were geniuses—and the one stupid mistake that cost them everything. Their arrogance blinded them to the cameras, the witnesses, and the forensic evidence. This is the moment the mask of superiority shatters, and they realize they were never as smart as they thought.
