DAYTON, Ohio (AP) -- An Ohio man has pleaded guilty to raping a boy authorities say was brought by the child's adoptive father to his home, where both men raped the boy.

The Montgomery County prosecutor's office said Friday that 32-year-old Patrick Rieder (REE'-dur) pleaded guilty to 27 counts including rape of a child under 13 and pandering sexually oriented material involving a minor.

The prosecutor says Rieder was sentenced to 25 years to life and labeled a sex offender.

Authorities say the boy's adoptive father gave Rieder and another man access to the boy.

The adoptive father has pleaded guilty to child rape for assaults on the boy and three other adopted children. The third man pleaded no contest.

The Associated Press isn't naming the father to protect the child's identity.
