41-year-old Jesse Calhoun was in court yesterday, arraigned on a fifth homicide in a string of murders that terrorized the Portland, Oregon community. Family members of some of the young victims, who all ranged in age from 22 to 32, were present as Calhoun pleaded not guilty. Calhoun has a long criminal history of violent crime, but was released early under a prison firefighting program. That’s when Calhoun is alleged to have committed his killing spree, and police say their investigation remains open, saying there could be additional victims.
