CENTRAL ISLIP - An ex-convict is accused of killing his neighbor with an ax and then hiding the body in his closet for nearly a week in Central Islip.

Police arrested Aston Barth after investigators found the body of Jason Campbell. Cops say that Barth admitted to choking the victim during an argument on Dec. 18. They say he then tried to cut off Campbell's head before stuffing the body in the closet.
