MIDLAND CITY, Ala. – Speaking into a 4-inch-wide ventilation pipe, hostage negotiators tried Thursday to talk a man into releasing a kindergartner and ending a standoff in an underground bunker that stretched into its third day.

The man identified by multiple neighbors and witnesses as 65-year-old retired truck driver Jimmy Lee Dykes was accused of pulling the boy from a school bus Tuesday and killing the driver. The pair was holed up in a small room on his property that authorities compared to tornado shelters common in the area.

James Arrington, police chief of the neighboring town of Pinckard, said the shelter was about 4 feet underground, with about 6 feet by 8 feet of floor space and a PVC pipe that negotiators were speaking through.

There were signs that the standoff could continue for some time: A state legislator said the shelter has electricity, food and TV. The police chief said the captor has been sleeping and told negotiators that he has spent long periods in the shelter before.

“He will have to give up sooner or later because (authorities) are not leaving,” Arrington said. “It’s pretty small, but he’s been known to stay in there eight days.”

Midland City Mayor Virgil Skipper said he has been briefed by law enforcement and visited with the boy’s parents.

“He’s crying for his parents,” he said. “They are holding up good. They are praying and asking all of us to pray with them.”

A local legislator said the mother told him that the boy has Asperger’s syndrome, an autism-like disorder, as well as attention deficit hyperactivity disorder, or ADHD. Police have been delivering medication to him through the pipe, he said.

Dykes was known around the neighborhood as a menacing figure who neighbors said 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.

The chief confirmed that Dykes held anti-government views, as described by multiple neighbors: “He’s against the government – starting with Obama on down.”

“He doesn’t like law enforcement or the government telling him what to do,” he said. “He’s just a loner.”
