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.
Melchor de Mencos
Melchor de Mencos is a municipality in the Petén Department of Guatemala with population 23,813. It is situated on the eastern border with Belize, and is the only major border crossing from Guatemala to Belize. 
The city was established in April 1960. It is named after Sergeant Major Melchor de Mencos y Varón, who in 1754 journeyed with a tiny contingent of Spanish colonial troops from what is now Antigua, Guatemala to the coast of present-day Belize, there to combat English "pirates" who had settled that region and established a self-governing community. A large signboard-map at the border crossing between Benque Viejo del Carmen and Melchor depicts Belize as Guatemala's eastern province, consistent with Guatemala's ongoing claim.
