Police issued an arrest warrant for Donald Hux after investigators found the body of Sandy Carl Huckabee on Sunday in Arkadelphia.
Former Huckabee spokesman Jim Harris says Sandy Huckabee's father was the first cousin of former presidential hopeful Mike Huckabee's father.
Authorities say Hux abducted his ex-wife, Amy Huckabee, and their three children before he dropped the kids off in southern Arkansas' Union County. The children weren't hurt.
Arkadelphia Police found the body of Amy Huckabee's husband, Sandy Huckabee, but they have yet to find Amy Huckabee.
Authorities say Hux is wanted on capital murder, kidnapping, burglary and firearms charges.
