Passer-by uses gun to halt attack By Nicklaus Lovelady email@example.com Brian Albert Broom/The Clarion-Ledger As customers watched in horror Sunday afternoon, a man stabbed a woman and attempted to set her on fire in the parking lot of a Jackson store, witnesses said. The attack was stopped by a passer-by, who held the man at gunpoint until police arrived, witnesses said. The suspect, Henry Watson, 42, was arrested and is expected to face aggravated assault charges, Jackson Police Department Cmdr. Lee Vance said. Watson's wife, Gracie Watson, 42, was transported to the University of Mississippi Medical center, where she was listed in good condition. "It wasn't five minutes from when she had left my line when I heard a scream outside," said Theresa Stuckey, a cashier at the Family Dollar at 516 Nakoma Drive in Jackson. "I looked out, and (the attacker) was on top of her stabbing her, and stabbing her and stabbing her. "She was screaming, 'Help, he's trying to kill me!' She was rolling on the ground, trying to get out of the way, but he kept stabbing her. He stabbed her about 20 times in the neck, back and arms." As the attack continued, people were yelling at the man to stop and honking their horns, Stuckey said. She said she called 911. "He was just standing over her hacking away," said Dolly Baker, who had just left the Save-A-Lot store next door when she saw the attack. Baker said she watched the man pour gasoline on the victim then try to strike a match. "He was literally trying to kill that lady in broad daylight," she said. Baker said a passer-by stopped the attack. "He told the man, 'Stop, or I'm going to shoot. And if you run, I'm going to kill you,' " Baker said. The man held Watson at bay until police arrived at the scene. "Right now, all we know is that (Watson) attacked his wife. For what reason, we don't know," Jackson Police Department Sgt. Eric Smith said. Police said they are looking for the passer-by who stopped the attack and would like to talk to him but don't know who he is or where he went. The incident occurred about 3:50 p.m. Smith said he did not know exactly how many times Gracie Watson was stabbed but said it was more than 10 times.
