Twenty-seven-year-old Jason Dunn pleaded not guilty yesterday in a Shasta County courtroom to an attempted murder charge in the attack on his father, Gregory. He appeared in court with his hands reattached, but heavily bandaged. According to court records, deputies who went to a Redding area home on June 17 found the elder Dunn lying in the driveway with multiple stab wounds and Jason Dunn standing nearby with both of his hands severed at the wrists. Authorities say Jason Dunn acknowledged inflicting both injuries, saying he and his father had been in an argument.
