Nemesio Oseguera Cervantes
According to the Mexican government, El Mencho may be hiding in the state of Jalisco, the CJNG's stronghold. However, they believe he does not stay in one place for too long, and travels across several municipalities in Jalisco and into the states of Michoacán, Colima, and Nayarit. He usually travels across the mountains and rural terrains in these areas since it provides multiple escape routes in the event that security forces attempt to encircle him. Authorities suspect El Mencho's inner circle is made up of mercenaries with former military training. His second security circle is much larger in size and serves as a rearguard to notify El Mencho's inner circle of suspicious activity and ambush potential parties that attempt to get close to him.
Calakmul
Calakmul is located in Campeche state in southeastern Mexico, about north of the border with Guatemala and north of the ruins of El Mirador. The ruins of El Tintal are to the southwest of Calakmul and were linked to both El Mirador and Calakmul itself by causeway. Calakmul was about south of the contemporary city of Oxpemul and approximately southwest of La Muñeca. The city is located on a rise about above a large seasonal swamp lying to the west, known as the El Laberinto "bajo" (a Spanish word used in the region to denote a low-lying area of seasonal marshland). This swamp measures approximately and was an important source of water during the rainy season. The "bajo" was linked to a sophisticated water-control system including both natural and artificial features such as gullies and canals that encircled a area around the site core, an area considered as Inner Calakmul. The location of Calakmul at the edge of a "bajo" provided two additional advantages: the fertile soils along the edge of the swamp and access to abundant flint nodules. The city is situated on a promontory formed by a natural high limestone dome rising above the surrounding lowlands. This dome was artificially levelled by the Maya. During the Preclassic and Classic periods settlement was concentrated along the edge of the El Laberinto "bajo", during the Classic period structures were also built on high ground and small islands in the swamp where flint was worked.
