A U.S. mountain climber, the buddy of a compatriot who died last Saturday on Mount Aconcagua, also lost his life while attempting to reach the summit of the highest peak in the Americas, in the western Argentine province of Mendoza, officials said Tuesday.

The latest victim was identified as David Reinhart, expedition companion of Eric Nourse who died Saturday, and of his brother Greg Nourse who was rescued alive.

From a height of 6,000 meters (19,670 feet), the three alpinists had undertaken last Friday the last stretch of a climb to the summit of Aconcagua, 6,959 meters (22,816 feet) above sea level, by the route of the Los Polacos Glacier.

On Saturday afternoon the company providing logistical services for the group warned Aconcagua Park Headquarters that a relative of the Nourse brothers had received a message from Greg's satellite phone with an alert that they were in difficulties.

The rescuers found Eric Nourse in critical condition, and several hours later he died of pulmonary edema followed by cardiorespiratory failure, despite attempts to revive him practiced by the emergency management team.

Meanwhile, Greg was admitted to a hospital in Mendoza but was out of danger, while the rescue brigade continued its search for Reinhart.

The rescuers finally found Reinhart's body at an altitude of 6,600 meters (21,600 feet), officials of the Mendoza Environmental Secretariat told the official news agency Telam.
