MIDLAND CITY, Ala. – A gunman holed up in a bunker with a 6-year-old hostage kept law officers at bay Wednesday in an all-night, all-day standoff that began when he killed a school bus driver and dragged the boy away, authorities said.

SWAT teams took up positions around the gunman’s rural property and police negotiators tried to win the kindergartener’s safe release.

The gunman, identified by neighbors as Jimmy Lee Dykes, a 65-year-old retired truck driver, was known around the neighborhood as a menacing figure 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 shotgun.
