Bulloch County sheriff's deputies surrounded a home Monday on Highway 80 West while a man who was wanted on outstanding domestic dispute warrants barricaded himself in a home with a gun. Calvin Dale Duke, 28, of Garden City, was wanted on warrants for aggravated assault, battery and third-degree cruelty to children regarding a Sept. 21 domestic dispute in which he allegedly choked his girlfriend and then fled, said Bulloch County Sheriff's Chief Deputy Jared Akins. Deputies went to the home earlier in the afternoon, around lunchtime, to look for Duke, but it appeared that no one was home and the house was locked, he said.
