(Portland, OR)  --  A grand jury says a Portland woman acted within the law when she shot an intruder to death in her home.  The decision cleared 33-year-old Tara-Alexis Ford, who shot and killed David Daniel McCrary of Gresham on June 26th when he was found in the bedroom of Ford's ten-year-old daughter.  Police said McCrary might have been suffering some kind of mental illness when he broke into the Southeast Portland house.
