Neighbors described Dykes as a man who once beat a dog to death with a lead pipe, threatened to shoot children for setting foot on his property, and patrolled his yard at night with a flashlight and a firearm.
Government records and interviews with neighbors indicate that Dykes joined the Navy in Midland City, serving on active duty from 1964 to 1969. His record shows several awards, including the Vietnam Service Medal and the Good Conduct Medal. During his service, Dykes was trained in aviation maintenance.
He had some scrapes with the law in Florida, including a 1995 arrest for improper exhibition of a weapon. The misdemeanor was dismissed. He also was arrested for marijuana possession in 2000.
He returned to Alabama about two years ago, moving onto the rural tract about 100 yards from his nearest neighbors.
