(Portland, OR)  --  Portland police have a man in custody, after he was accused of setting fire to a Southeast Portland church and a vacant house across the street.  Authorities say 46-year-old Jaime Calderon confessed to starting the fires.  Portland Fire & Rescue officials say crews arrived at the Eastside Free Methodist Church on Southeast 139th and Stark at around 1:45 yesterday morning and quickly extinguished the fire, but church officials say it will be about six months before the building is usable again.  Calderon is facing two counts of first-degree arson.
