According to Mexican press reports, the Mexican military shot and killed a US citizen on the Acapulco-Zihuatenejo highway Saturday night. The American was identified as Joseph Steven Proctor, either 32 or 35 years old, of Georgia.

The incident took place on kilometer 14 of the coastal highway, near the village of Cerrito de Oro in the municipality of Coyuca de Benitez in the state of Guerrero. For more than 30 years, the Mexican military has conducted patrols and checkpoints on the highway as part of its "permanent campaign against drug trafficking."

According to Lt. Francisco Javier Escamilla of the 68th Infantry Battalion, soldiers in a Hummer driving toward Coyuca encountered a Winstar pick-up truck traveling toward them. The truck opened fire on the soldiers, and when it refused to stop, the soldiers shot back, causing the truck to overturn.

The Mexican army did not initially report the incident, only issuing its statement after police found Proctor's body. Instead, an anonymous call to state police reported the truck and the body around 2:00am Sunday morning. When police arrived, they found Proctor's body in the truck. It had multiple bullet wounds. They also found an AR-15 rifle with a 41-cartridge clip holding only 34 cartridges.

Proctor's body was taken to Acapulco for forensic examination, then turned over to his wife, Mexican national Liliana Gil Vargas. Gil Vargas told the newspaper Reforma that her husband had left their home in Coyuca de Benitez at about 10:00pm Saturday night to go shopping at a supermarket.

State and municipal police are investigating. The US consulate in Acapulco is asking that the military cooperate in the investigation.

While the Mexican military has long played a limited role in enforcing drug prohibition, President Felipe Calderon unleashed it in December 2006, deploying some 50,000 soldiers and federal police in hot spots across the country. It is widely accused of human rights violations, ranging from rape and robbery to torture, murder, and forced disappearances.
