Investigation Discovery’s DISAPPEARED; The Silent Son (Season 8 Episode 2) This is the mysterious story of missing teen Macin Darrin Smith. He went missing on September 1st 2015 in Saint George, Utah. There appear to be inconsistencies in the parent’s description of what happened. “The most mystifying twist in the case” a 3-page note was found in the teens wallet six days after initially discovering the wallet. The father’s timeline has been called into question. Police seem to suspect one or more of the parents are involved in some way. Some say the parents have been less than forthcoming. What is presented is a picturesque family environment with some questionable parenting and a 30-year marriage that was headed for the rocks. This episode alone is worth the price of the entire season.
