An illegal immigrant from Mexico who previously served nearly two decades in federal prison, was indicted Tuesday after allegedly conspiring to move tens of millions of dollars in methamphetamine in the Atlanta area, leading authorities to seize nearly 1,600 pounds of the stimulant drug hidden in blackberry shipments. Gerardo Solorio-Alvarado, 44, of Mexico, was charged with conspiracy and possession with the intent to distribute methamphetamine. He previously served 17 years in prison after being convicted of felony possession with the intent to distribute methamphetamine and possession of a gun in a drug trafficking crime.
