SAN DIEGO (FOX 5/KUSI) -- The road for justice continues for the family of slain U.S. Drug Enforcement Administration (DEA) agent Enrique “Kiki” Camarena forty years later. The family is suing the Guadalajara Cartel members responsible for his murder after President Donald Trump designated ca rtels as terrorist organizations. This is happening at the same time Rafael "Caro" Gallardo, one of the cartel's leaders, is facing federal murder charges. “My brother was out here, trying to do good and get rid of these marijuana fields, but it continued and it continued and these cartels still to this day continue," said Myrna Camarena. "Is there ever going to be an end?" Retail theft bust at Las Americas outlet mall leads to 80 arrests Camarena, Kiki's sister, said that the lawsuit's goal is justice for her brother. In 1985, her brother was kidnapped, brutally interrogated and murdered by the Guadajalara Cartel. Camarena was also working for the DEA when her brother was kidnapped. She said it was a Sunday when her boss knocked on her door and broke the news that her brother was missing. “He says, ‘Your brother has been taken.' He didn’t use the word 'kidnapped.' He used the word 'taken.' I said, ‘What do you mean? He’s a policeman. He can’t be taken. He can defend himself,'" Camarena recalled. "'He’s been kidnapped,' he says. And I don’t remember that I fainted." A month later, she got the news that Kiki’s body was found. He was found next to the pilot who flew him over a marijuana field operated by the Guadalajara Cartel to collect evidence. For Camarena, the discovery of her brother’s body was the start of a road to get justice for her brother. “Why him? What did he do other than his job?" said Camarena. Three cartel leaders were held responsible for Kiki's death, Miguel Angel Felix-Quintero, Ernesto Fonseca-Carillo and Caro Gallardo. The family filed a lawsuit against all three and the Sinaloa Cartel last week, seeking compensation for substantial physical, emotional and psychological damages. It comes as Caro Gallardo is facing federal charges for Kiki's murder. Reports say he could face the death penalty. “We have waited 40 years for this. 40 years and he’s finally here," said Camarena. It’s something she says her mother would’ve loved to have seen. New bill to limit federal district judges “When my mother was on her death bed she said, ‘I wish I could be here when he’s arrested and brought to the us.’ But she didn’t make it," she said through tears, "so that makes it even harder." She said that when Gallardo was extradited to the U.S., she prayed and told her mom that she had gotten her wish. Kiki's death has not been in vain. Since his passing, his life has been honored every year in October at schools around the country with Red Ribbon Week, where students pledge to be drug-free. There is also a school named after him in Chula Vista. ...read more read less
