The court said the Austrian, who bought supplies for the family and rented the farm property, “played an essential role in the events and without his contribution it would not have been possible for the father to keep his children isolated from society for so long."
He was acquitted of the unlawful deprivation of liberty of the family's eldest three children and of abusing all the children.
The six children who were kept on the farm are now all young adults. Three older siblings had earlier left the family’s isolated life. Their mother died in 2004.
The time the Austrian has already spent in custody ahead of his trial will be deducted from his sentence.
