Three members of the Nelons, a Gospel Music Association Hall of Fame quartet, and the chairman of the board overseeing the Georgia Department of Corrections, were among seven people killed in a plane crash in Wyoming, according to a statement by a group member who was not aboard the aircraft.

The Nelons co-founder, Kelly Nelon Clark; her husband, Jason Clark; and their daughter Amber Nelon Kistler died in the crash Friday afternoon, according to a statement from another daughter, Autumn Nelon Streetman. She is the fourth member of the Georgia-based quartet.

"Thank you for the prayers that have been extended already to me, my husband, Jamie, and our soon-to-be-born baby boy, as well as Jason's parents, Dan and Linda Clark," Nelon Streetman said. "We appreciate your continued prayers, love and support as we navigate the coming days."

Also killed in the crash were Nelon Kistler's husband, Nathan Kistler, family friend Melodi Hodges, and Larry and Melissa Haynie, according to Nelon Streetman.

There were no survivors.

Larry Haynie was chairman of the Georgia Board of Corrections and was remembered for "a career of valued public service," according to a statement from Georgia Governor Brian Kemp.

The group was traveling to join the Gaither Homecoming Cruise to Alaska, according to a statement from Gaither Music Group, the sponsor of the cruise, which features numerous gospel singers and groups.

Gaither Music said Hodges was an assistant for the band and that Larry Haynie was pilot of the aircraft and Melissa Haynie was his wife. The aircraft was identified as a single engine turboprop Pilatus PC-12/47E.

The crash occurred about 1 p.m. in Campbell County, Wyoming, north of Gillette and about 402 kilometers (250 miles) north of Cheyenne, according to a statement from Campbell County spokesperson Leslie Perkins.

The National Transportation Safety Board spokesperson Keith Holloway said Saturday that preliminary information indicated the plane crashed following an "auto pilot issue during flight" and a team of investigators was headed to the site.

The Nelons were inducted into the Gospel Music Association Hall of Fame in 2016 and were winners of 10 GMA Dove Awards, including multiple song of the year and album of the year awards.
