AUGUSTA -- John A. Okie told a forensic psychologist that Alexandra "Aleigh" Mills resisted when he began to strangle her early on July 10, 2007. "Johnny, what are you doing?" Mills asked, according to Charles Robinson, a forensic psychologist who testified Thursday.

Robinson is the second psychologist to testify in the double-murder trial of Okie, 22, which is in its seventh day in Kennebec County Superior Court.

Robinson testified that Okie had paranoid schizophrenia at the time and continues to have it. Okie is on trial for killing Mills, and his father, John S. Okie, 59, in the Okie home on July 16, 2007.
