Lawyers for a man charged in a series of highway shootings say they're gathering several medical reports about the mental state of their client, a diagnosed paranoid schizophrenic. Attorney Mike Miller says the reports include information from several psychiatrists and date back at least eight years. Twenty-eight-year-old Charles A- McCoy Junior pleaded innocent today to the attacks that included a fatal shooting in November. He could face the death penalty if convicted of aggravated murder in the death of 62-year-old Gail Knisely. Under state law, McCoy could have pleaded innocent by reason of insanity today, and he still has the opportunity to do so later. His lawyers say it's too early to decide what they ultimately might do.
