Photojournalists place their cameras on the ground during a demonstration in Mexico City condemning the alleged murder of fellow journalist Regina Martinez, a correspondent for the Mexican investigative magazine Proceso. Ruben Espinosa, a photographer who worked for Proceso and other media, was among five people found slain early Saturday, Aug. 1, 2015, in an apartment in Mexico City, according to the magazine. He had recently gone into self-exile from the Gulf coast state of Veracruz, where he felt under threat, the magazine added. According to the Committee to Protect Journalists, 11 journalists have been killed in Veracuz since 2010, the most recent just a month ago. Two others, including Espinosa, were Veracruz journalists found dead outside of the state.
