A radio caller in Chile has been arrested after confessing to participating in 18 killings while enlisted as a soldier during the military dictatorship of General Augusto Pinochet.

After confessing to his war crimes on a Chilean talk show called “Chacotero Sentimental,” Guillermo Reyes Rammsy was identified and placed under house arrest by a judge, according to The Associated Press. He called using the pseudonym "Alberto."

The 62-year-old remorseful veteran described taking several people to the desert to shoot them in the head and then blow up their remains.

Tens of thousands of Chileans were rounded up in the aftermath of Pinochet's 1973 coup.

Reyes Rammsy discussed the term "disappeared," which is used explain as a descriptor for the men and women who were never found. "Have you heard where the disappeared are?" he asked the host, adding, "Nobody has told you where the disappeared are ... Well, it's because they aren't. They are totally disintegrated. Nothing remained."

The distraught caller, who claimed to be suicidal, spoke of the psychological stress that emerged in him during his time in Pinochet’s army. According to Reyes Rammsy, he had to fight the feeling that he was actually starting to enjoy the killing.

As quoted in The Guardian, he said the first time he killed he cried and was consoled by his lieutenant, but soon he grew used to the situation. “We shot them in the head and then blew up the bodies with dynamite, there was nothing left, not even their shadow,” he explained.

The government estimates that around 3,000 people were killed by the military and security forces during Chile’s so-called “Dirty War.”

Chilean President Michelle Bachelet was herself once a political prisoner during Pinochet’s regime. As the AFP reports, she counts herself lucky to have survived. "I was lucky compared to so many others," she said, "Many of them died."

This was not the first time Reyes Rammsy tried to confess his "Dirty War" deeds. The caller said he had written about some of his experiences in a blog back in 2007.
