A man convicted of trafficking cocaine in Marietta has been sentenced to 30 years in prison.

In June, a Cobb County jury convicted Ferrando Rodriguez, 41, of Gary, Ind., of trafficking more than 400 grams of cocaine.

Acting on a tip, police searched a tractor trailer driven by Rodriguez on June 25, 2015, along Franklin Road, and found the cocaine, which agents estimated had a street value of more than $3 million.

Besides the sentence, Rodriguez was also fined $1 million.

Two other men charged with Rodriguez previously pled guilty and were sentenced to prison. Jesus Ruben Rosillo, 53, of Texas, pled guilty in June 2016 to trafficking in cocaine and was sentenced to serve 25 years in prison and fined $1 million. He admitted he had packed the cocaine into the tractor trailer.

Javier Leonardo Rodriguez, 26, of Dacula, pled guilty in July 2016 to conspiracy to violate the Georgia Controlled Substances Act. He was ordered to serve 12 years in prison and pay a $300,000 fine. Rodriguez admitted he had driven with the other two men to check out a drug-transfer drop site.
