A Chilean judge has found 18 former officers guilty in connection with a wave of political executions in 1973 that became known as the "Caravan of Death."

Judge Juan Guzman Tapia closed his seven-year investigation Tuesday, saying he is satisfied with the results, and that the probe went further than he thought it would.

Following the 1973 coup that brought General Augusto Pinochet to power, a group of Chilean troops traveled from town to town, killing dozens of people opposed to the takeover.

Some 3,000 people were killed under General Pinochet's rule, which lasted until 1990.

The ex-dictator has been indicted on charges of murder and kidnapping.  The charges stem from "Operation Condor," a plan implemented in the 1970s by Latin American military leaders to repress political opposition.
