PORTLAND — A U.S. traveler detained for months in East Timor has been released from prison. Stacey Addison, 41, of Portland was arrested in September shortly after crossing the border into the Southeast Asian nation. The veterinarian was sharing a taxi with a stranger who asked the driver to stop the car so he could pick up a package. Police stopped the vehicle, determined the package contained methamphetamine and took everybody to the station. Addison was released from jail after a few days, but was ordered to remain in East Timor during the investigation. Then, in October, a prosecutor persuaded a court to rescind Addison’s conditional release and she was taken to a women’s prison despite not being charged with a crime. “I am overjoyed to learn of Dr. Stacey Addison’s release from prison,” said U.S. Sen. Jeff Merkley, D-Ore., who had been working to secure Addison’s freedom. “This is wonderful Christmas news.”Addison’s mother, Bernadette Kero of Klamath Falls, Ore., said in a phone interview she is “tremendously relieved,” and will be even more so when her daughter gets her passport returned. For now, Addison is staying at the guest house of former President Jose Ramos-Horta. Kero said she spoke with Stacey twice on Christmas Eve, and her daughter, though obviously happy, was still in some disbelief over the whole situation.
