A woman shot her adult son Monday afternoon after he pulled out a samurai sword during an argument, Fort Worth police said. The mother and her 21-year-old son were fighting shortly before 4 p.m. in the 3000 block of Forest Avenue, near East Lancaster Avenue. She shot her son in the leg after he pulled out a samurai sword during the argument, police said. The son was taken with minor injuries to John Peter Smith Hospital, MedStar spokesman Matt Zavadsky said. The mother, who has not been identified, will probably not face charges, police said.
