BANGOR — A doctor says a Maine woman knew what she was doing when she killed her husband.

WZON-AM reports that Dr. April O’Grady, the state’s rebuttal witness, said Tuesday that she doesn’t believe Roxanne Jeskey was having a seizure at the time of his death.

Jeskey’s lawyers say she suffers from seizures since having a brain tumor removed in 2004. Jeskey, who is using an insanity defense, is charged with killing Richard Jeskey on June 12, 2011, in a jealous rage. Police say she used weapons that included a box-cutter, plastic baseball bat and pliers.

A neuropsychologist who testified for the defense said Monday that Jeskey has a brain injury, post-traumatic stress disorder and a psychotic disorder and is at times not in touch with reality.
