Math error leads to early release of former radical

LOS ANGELES -- Just days after her release on parole, a former 1970s radical was headed back to prison Saturday to serve at least one more year after corrections officials said a miscalculation resulted in her early release.

Criticism over the early release from prison Monday of Sara Jane Olson, who lived as a fugitive for years in Minnesota, spurred a review of her sentence and the timing of her parole, Scott Kernan, the chief deputy secretary for the California Department of Corrections, said at a news conference. The review revealed that a 2004 miscalculation led to the former Symbionese Liberation Army member being released a year too early, he said.

Olson, 61, was detained at Los Angeles International Airport on Friday night and told her right to leave the state had been rescinded. She was sent to stay with family in Palmdale, where authorities kept watch outside the house overnight, and was arrested Saturday and imprisoned in Corona, about 50 miles southeast of Los Angeles, Kernan said.

Olson, who was formerly known as Kathleen Soliah, was charged in 1975 with attempting to bomb police cars with the SLA, a group best known for kidnapping newspaper heiress Patricia Hearst. But Olson vanished soon after she was charged and reinvented herself as a housewife -- changing her name to Sara Jane Olson, marrying a doctor and becoming a mother of three in St. Paul, Minn. She was arrested in 1999 after FBI agents acted on a tip from TV's "America's Most Wanted."

In 2001, Olson pleaded guilty to the attempted bombings. She pleaded guilty in 2003 to second-degree murder in the 1975 shooting death of a customer during a bank robbery in Carmichael, near Sacramento. After several adjustments, Olson's sentences, to be served consecutively, included 12 years for the attempted bombings and two years for the bank slaying, said Seth Unger, a Department of Corrections spokesman.

The clerical error that resulted in her release came from a failure to properly factor the Sacramento sentence into her parole calculations, Kernan said.

"This is an extremely unusual situation," said the department's general counsel, Alberto Roldan.

Roldan said the long period between Olson's crimes and her sentencing made the calculations especially difficult.

Asked repeatedly by reporters at the news conference why the thorough review wasn't done until after Olson was released, Roldan said parole calculations are done when a person comes into prison rather than when they are released, and a "triggering event" such as a court motion is required to prompt such a review.

He said Olson's sentence had been reviewed several times, and there was no special reason to review her case at the time she was freed. But he said after Olson's release, a reporter pointed out to his department that the Sacramento district attorney's office had expressed concerns about the calculations.

The SLA started in 1973 when no more than a dozen white, college-educated children from middle-class families adopted a seven-headed snake as their symbol and an ex-convict as their leader. Their slogan: "Death to the fascist insect that preys upon the life of the people."

Besides kidnapping Hearst, the group claimed responsibility for the murder of a school superintendent and was involved in an armed bank robbery and other violent activities. Eventually those activities caught up with the group's members, including Olson, who was charged in the attempted bombings.
