Luis Donaldo Colosio Murrieta

[1] Shortly thereafter, he began postgraduate studies at the University of Pennsylvania and research at the International Institute for Applied Systems Analysis in Austria before returning to Mexico.

[3][4] After a slow start, with the spotlight focusing on former foreign minister Manuel Camacho's negotiations with the EZLN guerrillas, Colosio appeared to get the traditional support of the political machine of the PRI.

On 6 March 1994, the anniversary of the Institutional Revolutionary Party (the PRI), Colosio delivered a controversial but popular speech in the nation's capital, in front of the Monument to the Mexican Revolution.

At 5:05 pm PST, on 23 March 1994, at a campaign rally in Lomas Taurinas, a poor neighborhood of Tijuana, Baja California, Colosio was shot in the head with a .38 Special that was originally purchased in San Francisco.

The authorities were criticized for their poor handling of Aburto, having shaved, bathed and given him a prison haircut before showing him to the media, which started rumors about whether that man, who looked so different from the one arrested, was really the murderer.

[9] Shortly after Colosio was assassinated, Salinas abruptly ended a meeting with Canadian Prime Minister Jean Chrétien, publicly referring to the slaying as an "act of infamy.

Colosio's father continued determined to uncover what he strongly suspected are hidden truths behind his son's very public murder and, in 2004, he published a book about the case.

He also criticized the political class that kidnaps the power to serve their evil groups and interests and he condemned the fact that calls for unity and solidarity from the leaders are not heard.

Colosio: El asesinato (2012), directed by Carlos Bolado, explored the aftermath of the assassination of the candidate and various conspiracy theories.

Mexican rock group El Tri wrote a song about the assassination of Colosio called "Con la cola entre las patas" (With the tail between the legs).
