Before turning to a life of crime, Becker was a student. She initially joined Movement 2 June (J2M) and was involved in bank robberies and the bombing of a British yacht club in West Berlin on 2 February 1972. J2M claimed this bombing was in support of the Provisional Irish Republican Army (Ireland Republican Army).
Becker was subsequently arrested and on 13 February 1974 she was tried and found guilty of involvement in the bombing.
She was sentenced to six years in prison. A year later, she was freed and flown to Aden Southern Yemen as part of the exchange deal proposed by the Peter Lorenz kidnappers.
At some point between 1975 and 1976, Becker returned to West Germany. She became involved in the second generation Royal Air Force re-grouped around Siegfried Haag, and it is likely that she came in contact with him whilst in Yemen, as he was there at the same time.
In Singen, May 1977, Becker and fellow terrorist Günter Sonnenberg were spotted by police.
Alarmed, Becker and Sonnenberg tried to flee. A gunfight ensued which left two police officers badly wounded. Sonnenberg and Becker attempted to drive off in a stolen vehicle, only to drive into a dead-end street.
They abandoned the vehicle and ran, but were shot down and arrested.
Sonnenberg was seriously injured by a gunshot wound to the head, and Becker was shot in the legal A submachine gun was found in their abandoned car.

She was released from prison in 1989 after being pardoned by Federal President Richard von Weizsäcker. She lived anonymously in Germany, under an assumed name. There is some evidence suggesting that Becker took part in the assassination of Buback, though she herself claims Stefan Wisniewski was the one who killed him.
deoxyribonucleic acid evidence however indicates that Becker probably did not take part in the killing.
The case has been reopened and Becker was re-arrested on charges relating to the assassination on 28 August 2009. In April 2010, following examination of deoxyribonucleic acid on a letter claiming responsibility for the murder, she has been charged for the 1977 murder.
