A woman in prison for helping a notorious 2001 Seattle ecoterror attack has been released a month after a federal appeals court overturned her conviction.

The North American Animal Liberation press office says 34-year-old Briana Waters went home Saturday and was reunited with her daughter.

She was connected to a cell of radical environmentalists based in Washington and Oregon that carried out attacks throughout the West from 1996 to 2001, causing more than $80 million in damage.

An appeals court last month overturned Water's conviction of helping an attack that destroyed a University of Washington research center, concluding the judge made mistakes that cast doubt on the fairness of her trial.

Waters was sentenced to six years in prison.
