On 21 May 2005 members of the Federal Preventive Police (Policía Federal Preventiva, PFP) opened fire in two different shooting incidents, killing three male university students and seriously injuring another young man in the northern Mexican city of Reynosa, Tamaulipas State. Immediately after the killings the police issued a public statement claiming that the young men fired at the police officers who responded in self-defence. Forensic investigations and a report conducted by the National Human Rights Commission into the killings contradict the police position and indicate that there were clear efforts to divert the course of the investigation into the killings. One year later, no one has been brought to justice. The families of the victims have been provided little information on the progress of the investigations and are still waiting for justice
