Federal authorities have announced the indictments of four people tied to one of the largest human smuggling rings in the world. One of those is currently in an Oklahoma prison after being found guilty of six counts of first degree manslaughter in a 2023 case.

Acting U.S. Attorney Joseph McNally called the criminal network "one of the largest human smuggling rings in the nation," on Monday.

Federal officials in Los Angeles announced charges on Monday against four men accused of leading "one of the largest human smuggling organizations in the United States," the U.S. attorney ​says.

Four men face federal charges on suspicion of leading a human smuggling operation that brought more than 20,000 illegal migrants into the United States from Guatemala since 2019, including seven who were killed in a car crash in Oklahoma in 2023,
