BEAVERTON, Ore. — A live-in caretaker charged with setting an Oregon woman on fire has been deemed mentally unfit to stand trial.

A Washington County judge sent 63-year-old Celia Schwab to the Oregon State Hospital for up to 60 days of treatment before a re-evaluation. The Oregonian/OregonLive reports ( ) that Schwab’s co-defendant, Maria Meisner, has been found competent to stand trial.

The women have pleaded not guilty to charges of aggravated murder, murder, arson and assault in the death of 74-year-old Kathryn Breen. Authorities say the Beaverton woman was set on fire two days before Christmas.

Court records show a judge in 2009 banned Schwab from providing elder care in Oregon.
