A Pennsylvania man will spend at least 900 years behind bars after being convicted earlier this year of hundreds of counts of child pornography and sexual abuse.

According to prosecutors, Thomas Holliday, 81, sexually abused a girl beginning when she was only 14 years old. The 81-year-old filmed almost every assault, KYW-TV reported.

On Tuesday, Judge Albert Cepparulo sentenced Holliday to at least 935 years — possibly lasting up to 1,800 years.

The victim was praised by prosecutor Michelle Laucella as "courageous" for going to authorities, KYW reported.

“I just think she wanted him to acknowledge what he did wrong and he didn’t,” she said. “He didn’t think he did anything wrong. So I think it was bittersweet for her.”

Holliday had denied the charges, maintaining that the two were in love. His attorney said an appeal would be likely, according to KYW.
