When he died, López Falcón had with him four cellphones, a push-to-talk device, US$1,260 and MXN$6,200 in cash, several credit cards, his Texas driver's license, a Rolex watch, a gold ring and necklace, and a business card from a McAllen-based construction company. When news of the murder was made public, it was not known that the victim was López Falcón and/or a suspected crime boss. Preliminary reports described the victim as a businessman from Monterrey; rumors the businessman was a crime boss, likely López Falcón himself, began circulating. Mexican authorities doubted the victim was López Falcón because they thought it was unusual that he was in Guadalajara, which was far from his center of operations. Investigators had information that he was hiding in McAllen. López Falcón's identity card named him by his alternate first name Adelio. Jalisco authorities suspected the victim was probably López Falcón and federal authorities did not discard this possibility. His identity was confirmed by the Jalisco authorities on 8 May after they cross-referenced his identity cards with information federal authorities had on file. Jalisco authorities confirmed that López Falcón had no pending criminal charges in Jalisco but said he was suspected of being involved in drug trafficking in Tamaulipas and Nuevo León. The same day, Jalisco's attorney general Gerardo Octavio Solís Gómez confirmed the PGR was taking over the case and placing it under federal jurisdiction; the case would be headed by the Specialized Unit Against Organized Crime (UEDO), one of the PGR's former branches. State officials requested the PGR's assistance on the case because of López Falcón's criminal profile and his alleged involvement in drug trafficking, a crime that falls under federal jurisdiction. The UEDO said the investigation would also include the charges of illegal possession of military-exclusive firearms and organized crime involvement against the suspects. They were expecting Jalisco authorities to open a separate homicide case under state jurisdiction. Federal authorities asked state officials to withhold information about the case from the public and recommended secrecy in the investigation. The federal government dispatched troops from the Federal Investigation Agency (AFI) and the PGR to Guadalajara. They were planning to increase security in Jalisco and Nuevo León to prevent a violent response from organized crime groups.
