A prison phone call between Kendra Duggar and Joseph Duggar offered more insight into their kids' whereabouts after their parents were arrested on separate charges. "I think Friday has probably been my hardest day, but that's crazy to say because Wednesday was crazy hard," Kendra, 27, told Joseph, 31, during a March 24 phone call from the Washington County Detention Facility, according to multiple outlets. Friday referred to the day Kendra was arrested on March 20, which was two days after Joseph was taken into custody.
