On August 12, 2012, Morales Pérez and his campaign manager, Juan Francisco Hernández Colunga, were driving home from a
quinceañera party at around 1:45 a.m. when several gunmen ambushed them in the streets of the city of
Matehuala,
San Luis Potosí. The ambush took place just 60 meters away from the party, when two white
Honda vehicles carrying a total of nine gunmen shot at Morales Pérez's vehicle after they tried to get away. Both of them died at the scene, while Claudia Martínez de Hernández, the wife of Hernández Colunga and the only living witness, was gravely injured and was taken to the nearest hospital; she could not identify the perpetrators. The Mexican authorities received the emergency call of the attack at around 2:00 a.m. and went to the scene, but Morales Pérez was found dead in the back seat of the car, while his campaign manager died in the driver's seat. More than 100
.223 and
7.62 mm caliber shells were found at the crime scene. The killers were not found but the Mexican authorities indicated that
Los Zetas were the probable perpetrators of the attack.
Background The state of
San Luis Potosí experienced an increase in drug-related violence several months prior to Morales Pérez's assassination. According to official figures, 39 people were murdered in July 2012 in the state, compared to the 13 killed during the same month in 2011. In the first two weeks of August 2011, 33 people were killed, including the gruesome discovery of 14 mutilated bodies inside a van on August 9. Later that day, the death toll reached 21 dead after the
Mexican Army and members of organized crime engaged in several gun battles throughout the state. The state authorities contributed the wave of violence to an infighting between rival groups of
Los Zetas that fight for the control of San Luis Potosí. Reportedly, the 14 bodies found inside the van were members of the
Coahuila-based faction of Los Zetas led by
Iván Velázquez Caballero. In addition, the surge in violence across the state may be partially attributed to the high summer temperatures throughout Mexico, since extreme weather conditions alter the patterns of drug harvesting and force the cartels to look for other sources of revenue during that time of the year. The "summer effect" – a term coined by Alejandro Hope, a security specialist – leads for more people to spend time outdoors, making criminal activities more visible, like drug sales, for example. In addition, the school calendar results in the absence of parental supervision, facilitating teenage recruitment by the drug trafficking organizations. Hope argues that the media outlets have played an important role in the perception of the drug violence documented in August 2012 in Mexico. The Mexican newspaper
Milenio reported more than 38 killings throughout the country on August 9, 2012. Although these figures received a lot of coverage, Mexico experiences a rate of 60 drug-related murders per day, but these killings usually never make it to the national media and are rarely reported. More than 1,000 people attended the ceremony, including local politicians and former mayors of Matehuala. After the mass was over, a
mariachi group played songs in memory of Morales Pérez and Hernández Colunga outside the chapel where the mass was held as their coffins were taken to Jardines de la Luz cemetery. In response to the drug-related murders in San Luis Potosí, the Mexican government deployed 15,735 federal agents to seven states across Mexico on August 14, 2012. Of these, 11,835 are from the
Mexican Armed Forces and 3,900 are from the
Federal Police. Five police officers from the municipality of Matehuala were detained on August 17, 2012 for their alleged participation in the assassination of Morales Pérez. According to the evidence presented by the authorities, the police officers were watching over at the party where Morales Pérez was present but were reportedly "called to the station" just before the attack occurred. The
Institutional Revolutionary Party (PRI) appointed Héctor Fermín Ávila Lucero as the mayor of Matehuala on 21 September 2012. ==See also==
