(Beaverton, OR) -- The man accused of murdering a Beaverton nurse is pleading not guilty. KATU-2 reports 27-year-old Bryce Shubert pleaded not guilty in court yesterday to charges of first-degree murder, first-degree kidnapping and second-degree abuse of a corpse. Shubert had previously pleaded not guilty to second-degree murder, but a grand jury upgraded the charges last month. Shubert is accused of killing 32-year-old Melissa Jubane, who was reported missing on September 4th after she failed to show up for work. Police found her body several days later. Investigators say Shubert lived across the hall from Jubane in their apartment complex in Beaverton.
