An unemployed Las Vegas chef who turned himself in at a police station described in grim detail how he stabbed his wife to death in their apartment kitchen and said he'd do it again, according to an arrest report made public Monday. Richard Dahan told police he was a kidney transplant recipient in failing health who lost his job as a chef at a Las Vegas Strip casino resort. (AP Photo/ Las Vegas Police Department)
