(Hillsboro, OR)  --  The murder trial of Jaime Tinoco is underway in Washington County court.  He's accused of stabbing 29-year-old Nicole Laube to death at the Timber Creek Apartments in August 2014, when he was just 17-years-old.  Laube worked at the complex and was distributing leasing fliers when she was killed. During opening statements yesterday, the prosecution played part of a confession tape in which Tinoco said the murder made him feel "powerful" and "high."  The defense claims Tinoco is mentally ill and that he was pressured to confess.
