A convicted sex offender pleaded guilty Friday morning to sexually assaulting an 11 year old and her 12 year old sister.
Earl Dean Raff pleaded guilty to two counts of sexual assault on a child by a person in a position of trust.
Officials say the 25-year-old abused the two girls for a period of seven months while they were staying with him.
Raff was convicted of sexually abusing a member of his family in 1999 and was arrested for failing to register as a sex offender in 2001.
He'll be sentenced in February for this most recent case. Right now he's being held on a $250,000 bond.
