Möller was convicted for the 24 May, 1972 bombing of the U.S. Army Base in Heidelberg. Möller was one of two people who drove bomb-filled cars onto the base; the explosions killed three American soldiers, Capt. Clyde Bonner, Charles Peck, and Ronald Woodward. She was arrested 9 July, 1972 after being set up by Hans-Peter Konieczny.

Möller was the sole survivor of Stammheim Prison's "Death Night," when Andreas Baader, Gudrun Ensslin, and Jan-Carl Raspe either committed suicide, or were murdered, depending on whom you choose to believe. Möller supposedly used a knife to stab herself in her chest several times, missing her heart by millimeters.

After 22 years in custody, Möller was released from Luebeck prison on 1 December 1994.
