A man who was being beaten by a home invader got control of the gun from his attacker and shot him dead on Tuesday, Shreveport police said. A third man fled after the shooting and was being sought on home-invasion charges. The robbery attempt and subsequent shooting happened about 10:45 a.m. at a house at 79th Street and St. Vincent Avenue. Police said 23-year-old Martin Gobert answered a knock at the door of his house and was attacked by a man, who beat him with an assault style rifle. The two men fought, Gobert got control of the gun and shot 18-year-old Jeremy Bell several times, killing him, police said. Police said Gobert was beaten in the head and upper part of his body. He was taken to LSU Hospital with what were described as non-life-threatening wounds. No charges had been filed against him as of Tuesday evening. Authorities were investigating to determine what led to the home invasion. They also sent dogs into the house to search for evidence, including drugs. Police identified the man who fled the scene of the shooting as Jerome Hughes, 23, of the 200 block of East Gregg Street. Police Cpl. Bill Goodin said Hughes knocked on the door of the house and Bell, who had been standing behind him, charged into the house.
