Robert Fritch was aired on the November 3rd, 1993 episode of Unsolved Mysteries. Fritch was a successful Southern California real estate agent who was wanted for continously molesting his adopted daughter for over twelve years. He has been on the run ever since he was charged.
According to Unsolved Wikia, Fritch remains at large as of this posting date (11/15/2015)
There is a lack of other information available online about this case. I do not know Fritch's wanted year and am only assuming it's around the 1990's since that's when he was aired. For now, I'd contact your local police or crime stoppers line if you know Fritch's whereabouts.
