The mother of the French gunman accused of killing seven people in an ethnic shooting rampage, before being shot dead Thursday in Toulouse, was released late Friday without charge. Zoulika Aziri was questioned by police, who are trying to determine whether the self-proclaimed al Qaeda member Mohamed Merah acted alone. The probe has turned to his older brother Abdelkader. Police said they have gathered evidence to suggest that he helped his brother carry out the shootings. He and his girlfriend remain in custody in Paris and could face charges.
