CHEYENNE, Wyo. (AP) — A psychiatrist who evaluated Wyoming's lone death row inmate before his state court trial nearly 10 years ago says evidence unearthed by the inmate's new legal team indicates he suffers from mental illness.

Windsor, Colo., psychiatrist Dr. Kenneth Ash testified Wednesday in federal court in Cheyenne.

Ash says new information about the background and family medical history of death row inmate Dale Wayne Eaton points to a mental illness called bipolar 2. People suffering from the illness have periods of depression interspersed with intense activity.

A federal judge is holding a multi-week hearing on Eaton's claims that he didn't get an adequate defense before receiving the death penalty in 2004 in state court for the 1988 rape and murder of 18-year-old Lisa Marie Kimmell of Billings, Mont.
