 Early in the morning of 28 April 2012 , Martínez Pérez was murdered inside her home in Xalapa after being severely beaten . A suspect was arrested in October 2012 and publicly confessed to the murder , while the Mexican authorities concluded that the motive of the murder was theft . But the suspect later retracted his confession and stated that he had been tortured and threatened by officials to lie and admit to the murder . Investigators have relied solely on the suspect 's confession to incriminate him ; the DNA and fingerprint samples collected at the murder scene did not match the suspect 's according to sources close to Committee to Protect Journalists .
