NORMAN, Okla. (AP) - A clinical psychologist says alcoholism and mental health issues impaired a 52-year-old man's ability to form the intent to kill three women.
Dr. Bill Sharp testified Monday in the murder trial of William Eugene Davis. Davis is charged with three counts of first-degree murder in the September 2007 shooting deaths of his two sisters and the mother-in-law of one of the women in Norman.
Sharp says Davis' blood-alcohol content shortly after the killings was .308 - nearly four times the legal limit of .08. He says Davis had a substantially reduced capacity to form the intent to commit the crimes.
Defense attorneys maintain Davis suffered an alcohol-induced blackout and doesn't remember what happened.
Davis has pleaded not guilty. Prosecutors are seeking the death penalty.
