(CNN) -- Adam Mayes -- accused of murder and kidnapping in a case involving a Tennessee mother and her three daughters -- has died, FBI spokesman Joel Siskovic said late Thursday. The two sisters he allegedly kidnapped were found alive, law enforcement sources said. There had been conflicting reports about whether Mayes was dead or alive after he reportedly shot himself in Union County, Mississippi. Daniel McMullen, FBI special agent in charge in Jackson, Mississippi, said that officers with the Mississippi Highway Safety Patrol and state Department of Fisheries, Wildlife and Parks rescued Alexandria and Kyliyah Bain, "alive and unharmed."
