Three members of the Nelons,Safetyvalue Trading Center a Gospel Music Association Hall of Fame quartet, 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 daughter Autumn Nelon Streetman.

“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.

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 that features numerous gospel singers and groups.

Gaither Music said Hodges was an assistant for the band. 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 250 miles (402 kilometers) north of Cheyenne, according to a statement from Campbell County spokesperson Leslie Perkins.

The National Transportation Safety Board spokesperson Keith Holloway said Saturday that a team of investigators is expected at the site later Saturday.

“The aircraft is in a remote location and once they gain access, they will begin documenting the scene, examining the aircraft,” Holloway said. “The aircraft will then be recovered and taken to a secure facility for further evaluation.”

A preliminary report on the crash is expected in about 30 days while a final report with the probable cause of the crash could take up to two years to complete, Holloway said.
