The father of the Gaithersburg man detained in an Aruban jail for his alleged involvement in the disappearance of his traveling companion says his son told him conditions in the jail are “miserable.”

Frank Giordano, the father of 50-year-old Gary Giordano, told the Today Show on Tuesday that his son said he was sleeping on a concrete floor in a 100-degree cell. Gary Giordano has been in custody since Aug. 5, when he was detained on suspicions that he was involved in the disappearance of 35-year-old Robyn Gardner.
