A woman allegedly killed her husband and two stepsons here and then presented a fabricated version of the incident by informing police that they were being beaten up by unidentified assailants, officials said on Sunday. The woman was arrested after she confessed during police questioning that she killed them fearing that her daughter may not have any share in her husband's property. The incident took place late Saturday night and the woman informed police that two masked men were beating up her husband and children.
