Prison guards escorts handcuffed inmates who are looking for a pit in a rural area close to Chaguani, Colombia, June 18, 2015. As the government wades through complex peace talks with the FARC, human rights advocates and families hope rebels, like paramilitaries before them, will reveal grave locations as part of a deal which would allow them to avoid long prison terms and even enter politics. Victims' groups warn that unless more bodies are exhumed, identified and returned to loved ones, Colombia risks handicapping post-conflict development. Picture taken June 18, 2015.
