Salazar would obtain cars that were driven to Mexico, where drugs were loaded into the engine compartments. Couriers would then drive them back across the border into the US, prosecutors said.
The scheme began around 2015, authorities said.
By the time of his arrest last year, “Salazar had become so involved in drug trafficking that he was commissioning a Mexican songwriter to write a drug ballad known as a ‘narcocorrido’ about him,” the US attorney’s office said.
“In one line that Salazar suggested to the songwriter, he boasted: ‘I wanted to study and became a soldier, but I liked the fast life better,’” the office said.
Some of the couriers recruited by Salazar were former Marines or classmates at Southwestern College in Chula Vista.
“This case involved a Marine who was supposed to protect and defend our country, but instead brought great harm to Americans by trafficking fentanyl and other dangerous drugs,” US Attorney Randy Grossman said. “He also betrayed his solemn oath by recruiting other Marines to do the same.”
