"My father was 79," says Donaldo Gomez, who lives in the steep Andes Mountains of Colombia. "He wasn't sick a day in his life. And then he gets killed by a mine!"
Gomez, whose father died in 2003, lives in an area that was once swarming with guerrillas. When the Colombian army moved into the region a few years ago, the Revolutionary Armed Forces of Colombia, or FARC, planted land mines to try to stop them. The same thing happened in many parts of the country.
