Raul Cueves is behind bars in Idaho on a first-degree murder charge after allegedly killing the prime suspect in his mother's murder. Police officers were called to a home where they found Cueves' mother, Michela Luna, with several stab wounds, as she was pronounced dead at the scene. Investigators said they quickly identified the suspect, and although they tried to locate him overnight, the next morning deputies found the suspect 25 miles away, slumped over in a car with the engine still running. He too had been stabbed and died from his injuries.
