Ulrike Meinhof

Meinhof, who took part in the RAF's "May Offensive" in 1972, was arrested in June of that year and spent the rest of her life in custody, largely isolated from outside contact. In November 1974, she was sentenced to 8 years in prison for complicity in a near-fatal shooting in what had been her first RAF operation, the successful jailbreak of Andreas Baader in 1970.
From 1975, with Baader and two other RAF leaders, Gudrun Ensslin and Jan-Carl Raspe, she stood trial on further charges of murder and attempted murder. Before the end of the trial, she was found hanged in her cell in the Stammheim Prison. The official finding of suicide sparked controversy, with her sister, Wienke Zitzlaff, stating that Meinhof had told her only days before her death: "You can stand up and fight only while you are alive. If they say I committed suicide, be sure that it was a murder."
One year later, on , two members of the RAF assassinated the Federal Attorney-General Siegfried Buback as revenge. Provided by Wikipedia
