LOS ANGELES—A former U.S. Marine from Whittier who prosecutors say led a six-man scheme to smuggle high-powered weapons and ammunition to one of the most feared transnational drug cartels in Mexico was sentenced Jan. 8 to eight months behind bars.
Marco Antonio Santillan, 53, pleaded guilty in May 2022 to conspiracy to violate export regulations and conspiracy to commit money laundering, according to the U.S. Attorney’s Office.
