'German Fritzl' accused of fathering 7 kids with stepdaughter

London, Feb 16 (ANI): A man labelled the 'German Josef Fritzl' has been accused of fathering seven children with his stepdaughter.

The 48-year-old German, identified only as Detlef S., sat stone-faced at the state court in Koblenz as Judge read aloud a letter written by his daughter, now 18, reports the Daily Mail.

"You made my life a living hell," she wrote.

Detlef S. is charged with 350 counts of sexual abuse-tormenting his daughter, stepdaughter and stepson for over 20 years, reports the Daily Mail.

He also faces 35 other sexual counts for forcing the two girls to have sex with other men for money. He faces up to 15 years in prison if found guilty.

Detlef S. first began molesting his daughter when she was nine, and after the 12th birthday party he regularly sexually assaulted her.

He had already been abusing his twin stepchildren, who are now 28, starting in 1987 when they were only four years old, until 2010.

After that testimony, the judge said prosecutors are also investigating whether the suspect assaulted a daughter he had with his stepdaughter in 2004.

"I wanted to give my sister strength to go on with this. We are in this together, and together we are trying to have the strength to live through this. It would make no sense to do this alone," said Bjoern B., the stepson.

Defence attorney Thomas Dueber said his client was not admitting the charges against him.

"He acknowledged paternity ... but paternity is not part of the indictment. He's innocent until proven guilty," he said. (ANI)
