When he was finally caught, Rosalio Reta told detectives here that he had felt a thrill each time he killed. It was like being Superman or James Bond, he said.
“I like what I do,” he told the police in a videotaped confession. “I don’t deny it.”
Mr. Reta was 13 when he was recruited by the Zetas, the infamous assassins of the Gulf Cartel, law enforcement officials say. He was one of a group of American teenagers from the impoverished streets of Laredo who was lured into the drug wars across the Rio Grande in Mexico with promises of high pay, fancy cars and sexy women.
