(Portland, OR) -- A Portland rapist who could have been released from prison later this year has been convicted again, 30 years after his crime. James Jackson had to be retried, because the original jury verdict wasn't unanimous. A U.S. Supreme Court decision now requires unanimous verdicts. In 1995, Amy Countryman was 18 years old when she met Jackson at Pioneer Courthouse Square. She testified that he seemed nice and took her to a playground, threatened her with a gun and raped her. Prosecutors say the verdict is a testament to the victim's strength and courage to return to court 30 years later to confront her attacker.
