Ritterbush escaped from the Utah State Prison 10 years ago after serving six months of a five years to life sentence for attempted sexual abuse of a child. He has not been seen since the escape.
The FBI says the man has a long history of sexually abusing children and repeated his crimes despite charges and counseling. Investigators believe the man may be in Alaska or Canada; however, he is known to prefer Wyoming, Idaho and Utah and may have been seen recently in Idaho.
He is an experienced truck driver, diesel mechanic and ranch hand. He is probably living with a woman and may have married under an assumed name.
