A suspect in the killing of an off-duty Florida sheriff's deputy, who was gunned down at a truck stop while trying to intervene in a domestic battery incident, was captured Sunday in North Carolina, authorities said. The suspect, 29-year-old Demaurea Grant, was taken into custody without incident around 7:30 a.m. by the U.S. Marshals Service's Fugitive Task Force at a home in Gastonia, North Carolina, about 400 miles from where he allegedly fatally shot Deputy Brad McNew, a corrections officer for the Jacksonville County Sheriff's Office, officials said. "As the leader of this agency, I'm grateful for the quick arrest of a man who tragically took the life of a member of the JSO family," Jacksonville County Sheriff T.K. Waters said during a news conference Sunday afternoon.
