A black South Carolina homeowner was in serious condition Friday after being shot by a white deputy sheriff who mistook him for an intruder. The shooting occurred in the same county as the April 4 police shooting of Walter Scott, an unarmed black man. "We're as sorry as we can be," Charleston County Sheriff James Alton Cannon Jr. said. The victim, Bryan Heyward, called 911 around 11 a.m. Thursday to report that armed men were trying to enter his mobile home, authorities said. Two deputies arrived and were told that shots had been fired and two black suspects had been fleeing the back yard, the sheriff's office said. When Heyward, 26, appeared in the doorway, holding a .40 caliber handgun that he kept to protect himself, one deputy told him to drop it. Heyward did not immediately do so and was shot twice moments later, hitting him in the neck with a single round.
