On 18 December of the same year, Haule was implicated in a plot to bomb a NATO school in Oberammergau. She allegedly parked a car full of explosives outside the school, however the attack failed due to a technical glitch.
On 1 February 1985, Haule was involved in the assassination of Ernst Zimmerman, in Gauting. Zimmerman was chairman of the board of the aircraft engine manufacturer MTU, he was shot through the head in his home. He was 55 at the time of his death. The assassination was carried out in the name of Patsy O'Hara.
Haule was due for release in 2001, but the Rhein-Main Air Base bombing and murder of Edward Pimental charges were brought against her. New evidence, which involved Haule's own letters to another RAF member in prison containing self-incriminating information, were used to prove her guilt. She had her sentence extended, and was moved to a women's prison in Neukölln. She stated that 'an end to her detention was not foreseeable.'
Parole was granted on 17 August 2007, with her release set for 21 August. However, officials released her on the 17th in order to protect her from the media. She has since shown no remorse for her actions as a member of the RAF.
