According to the Forensic Medical Service, he was been badly beaten, especially on the head, and died of the injuries.

Tens of thousands of people participated in a silent "March for Peace With Justice and Dignity" in Mexico City on May 8 to call for an end to the US-backed militarization of Mexico's fight against drug trafficking. Protesters, most of them dressed in white, carried signs reading: "No more blood," "Justice," "Peace," "Let's stop the bullets," "Life isn't trash" and, above all, "We've had it up to here" (estamos hasta la madre). More than 35,000 Mexicans have died in drug-related violence since President Felipe Calderón Hinojosa sent troops into the streets soon after taking office in December 2006.

On May 3 a panel of four experts presented United Nations (UN) secretary general Ban Ki-moon with their report on the origin of the cholera epidemic that broke out in Haiti last October. As of April 21 the disease had caused 4,575 deaths, according to the Ministry of Public Health and Population (MSPP). Almost 300,000 people have contracted cholera, and the number is expected to rise as the rainy season starts.

The Native Federation of the Río Madre de Dios and Tributaries (FENAMAD) issued a statement protesting that the state company PeruPetro has demarcated three new oil exploration blocs in Peru's southern Amazon region of Madre de Dios. The new blocs—numbered 187, 190 and 191—are located in the provinces of Tahuamanu and Tambopata, and bring to 22 the number of new exploration blocs instated nationally under President Alan García. FENAMAD charges that the new blocs threaten the Manú Biosphere Reserve and the Vilcabamba-Amboró biological corridor—already under threat by the operations of Hunt Oil and Repsol YPF in Lot 76, established in the ancestral territory of the Harakmbut, Yine and Matziguenka indigenous peoples. Hunt and Repsol have concluded seismic exploration in the bloc, over the protests of traditional indigenous leaders of the Amarakaeri Communal Reserve, which overlaps with the exploration bloc. The Hunt-Repsol consortium is now about to drill eight test wells in the bloc. (FENAMAD, May 6)

Rescue crews recovered the last of 14 bodies May 8 from the Pozo 3 coal mine hit by a gas explosion in Mexico's northern Coahuila state, while Labor Secretary Javier Lozano called for an overhaul of mine safety in Mexico and the federal Prosecutor General opened an investigation into the disaster. Mexican officials said the May 3 blast was caused by a buildup of gas. A teenage boy who was evidently employed illegally at the mine, Jesús Fernando Lara Ruiz, had his right arm blown off in the explosion. The National Union of Mine and Metal Workers and the Like of the Mexican Republic (SNTMMSRM) said the mine's work force was not unionized, and protested the "completely unsafe conditions under which coal mines operate in the country, and especially in this region known as the coal belt."

Amnesty International (AI) accused forces loyal to Moammar Qaddafi of committing war crimes in Misrata in a report issued May 5. According to the report, Qaddafi's troops have employed excessive use of lethal force against unarmed protesters, turned sniper fire on civilians in residential areas of the city, and deliberately used civilians as "human shields." "Shielding," AI asserted, "is a violation of international humanitarian law and constitutes a war crime." Additionally, according to AI, Qaddafi's forces used cluster munitions, which are heavily criticized by international observers and have been the subject of international eradication efforts. Misrata appears to be targeted as a result of its declaration in February of allegiance to opposition forces. While many have been able to escape the widespread violence, those left behind continue to suffer:

Afghan lawmakers on April 30 voted to approve the Turkmenistan-Afghanistan-Pakistan-India (TAPI) gas pipeline agreement. The Afghan parliament's International Liaison Commission said the agreement will boost the country's economy and strengthen relations between the four nations involved in the project. About 7,000 personnel will be assigned to ensure security for the project in Afghanistan, said Muhammad Anwar Akbari, a member of the commission. The cost of the project is estimated at around $7.8 billion, with construction to begin by 2012 and completion projected for 2014. Reports referenced an unnamed "American firm" that will be involved in building the pipeline.
