A German man accused of forcing his stepdaughter to father eight of his children as well as sexually abusing his stepson and daughter goes on trial next week, a court spokesman said Thursday.
The 48-year-old man, named in media reports as truck driver Detlef S., is accused of 350 counts of sexual abuse and grievous sexual assault of minors.
Between 1987 and 2010, the man is suspected of abusing the trio and even farming the two females out to other men for sexual abuse in exchange for money.
One of the man's neighbours told the Rhein-Zeitung local daily: "We often wondered about the several children in his house.
The stepdaughter, now 27, has seven children by her stepfather aged from 11 years to 15 months, her lawyer Katharina Hellwig said. An eighth child died.
Authorities were alerted after the man's biological daughter, 18, wrote a goodbye letter to the mother which was intercepted by her half-sister, Hellwig said.
The mother, who is in her 50s, is expected to appear as a witness in the trial and prosecutors are not charging her with any offence, Hellwig added.
"It looks as if she repressed what went on."
