Nine arrests made in connection with 2022 human smuggling tragedy that killed 53 migrants.

Four more arrests have been made in connection with the death of 53 migrants found in a sweltering tractor trailer in San Antonio, Texas, one year ago. The four Mexican nationals were arraigned on Tuesday and charged with conspiracy to transport migrants illegally resulting in death, among other charges. Two others connected to the incident were arrested last year and remain in federal custody without bond. The defendants face a maximum of life in prison if convicted. U.S. Attorney General Merrick Garland said human smugglers who put people's lives at risk for profit and break the law cannot hide for long.
