(Portland, OR)  --  A 28-year-old man is pleading not guilty to charges that he tried to kill another motorist in southeast Portland.  The Oregonian reports that Anthony Lunetta of Gresham pleaded not guilty yesterday to nine counts of attempted murder and assault.  He is accused of shooting a gun into a car in December after a traffic disagreement.  Authorities say the bullet barely missed a one-year-old child inside the vehicle.
