(CNN) A Pennsylvania man was convicted Tuesday of sexually assaulting six young sisters married off by their parents in return for financial support.

Lee Kaplan, 51, was found guilty on 17 charges including child rape, statutory sexual assault, and indecent assault, the Bucks County district attorney said.

The verdict came almost a year after police said they found Kaplan living with 12 females at his Feasterville home, including an 18-year-old who prosecutors said was "gifted" to him after he provided financial support for her parents.

According to the criminal complaint, Kaplan fathered two children with the 18-year-old, who was just 14 when her first child was conceived.

Kaplan's attorney, Ryan Hyde, said his client maintains his innocence.
