Thomas Holst

Between 1987 and 1989, Holst raped, tortured and dismembered three women in the south of Hamburg. A psychiatric report described Holst as "untreatable and with extreme relapse probability."

On September 27, 1995, his former therapist Tamar Segal helped him escape from the high-security wing of Klinikum Nord's forensic science of the former LBK Hamburg in Langenhorn. The police search was initially inconclusive, but suspicion arose against Segal. After this escape assistant had been arrested three months after the escape, Holst surrendered himself on December 30, 1995 at the Police Station 31 in Hamburg's Uhlenhorst.[1]

On March 13, 1997, Holst and Segal got married in the Hamburg Detention Center. In 2003, the district court of Hamburg dismissed Holst's claim to the consummation to Segal. It was about involuntary treatment, to meet regularly without observation with his wife in a visitor's room of the hospital north. The hospital refused this, pointing to the danger to his wife's life and threatened with risk of absconding. Holst appealed against the judicial relief, but it was unsuccessful.
