After two years of preliminary hearings, she was sentenced to 8 years' imprisonment on
29 November 1974. Meanwhile the trial continued; it would have almost certainly resulted in a life sentence had it been concluded. Though if that had been the case she might well have served 20 years before being paroled.
On
9 May 1976 she was found hanged by a rope, fashioned from a towel, in her cell in the
Stammheim Prison. It was suspected that her death had been self-inflicted and this verdict of
suicide was confirmed later through further enquiries. It was later discovered that she had become increasingly isolated from other RAF prisoners. Notes exchanged between them in prison included one by
Gudrun Ensslin, describing her as 'too weak'. The official findings were not accepted by many in the RAF and other militant organisations and there are still some who doubt their accuracy and believe that she was murdered by the authorities. In
2001, the findings of the inquiry were published under the title
Der Tod Ulrike Meinhofs. Bericht der Internationalen Untersuchungskommission (ISBN 3-492-24058-5).
Meinhof's body was buried six days after her death in Berlin-
Mariendorf. In late
2002 it was discovered, following investigations by her daughter Bettina, that her brain had been retained (apparently without permission) by a hospital in
Magdeburg following the autopsy performed as part of the investigations in Meinhof's death. Bernhard Bogerts, a psychiatrist from the local university who has examined the brain, has controversially claimed that Meinhof's 'slide into terror' may be due to surgery in
1962 for removing a brain tumour. On Bettina's request, the brain was interred in Meinhof's burial place on
22 December 2002.
