At his sentencing Thursday, he repeatedly blamed the girl, calling the victim a liar.
The girl, now 12, was forced to give birth at 11 and forced to give the baby up for adoption, Deputy Grant County prosecutor Lisa Glancy told the Chronicle-Tribune.
"He showed no remorse," Glancy said. "Absolutely none."
The girl gave an impact statement during Thrash's sentencing, saying that the crimes forced upon her caused her pain and have impacted her life in many ways, the newspaper reported.
The girl’s mother is also facing charges in the case, including aiding in child molesting, neglect and assisting a criminal.
