Split Personality At Work?

Police, including SWAT officers, were called to an apartment in Mesa, Ariz., in June after neighbors reported a fight between a man and woman that included yelling and breaking things inside. When they arrived, they found only a 21-year-old man, conducting the fight by himself, alternating a high-pitched voice with a low-pitched one. He was referred for a medical exam.
