A repeat sex offender could be spending the rest of his life behind bars.
23 year-old Rodney William Grask* was sentenced to 18 years in prison Friday.
But the sentence may be longer because he's been convicted 4 times since 2000.
The latest conviction came after he pled guilty for fondling an 11 year-old girl in May.
Graski was in a rehabilitation program when the most recent assault occured.
