The 31-year-old editor of El Salmantion, an online newspaper, was killed in the Mexican state of Guanajuato by unidentified assailants.
The SNRP, an IFJ affiliate, said that Rangel was shot several times by gunmen in the Villa Salamanca colony where he had gone to report on the discovery of human remains dumped in plastic bags. His attackers fled the scene, the SNRP added.
