Marietta/Cobb/Smyrna Narcotics Unit agents found more than 25 pounds of fentanyl and a gun inside a vehicle during a Cobb County traffic stop on Monday.

A month-long drug investigation ended with a major narcotics seizure and a suspected drug trafficker in custody, according to the Cobb County Sheriff's Office.

MCS Narcotics agents stopped a vehicle traveling through Cobb County. A K-9 officer alerted handlers to look inside, prompting a search that uncovered approximately 11.43 kilograms of suspected fentanyl. The seized synthetic opioids field-tested positive and have an estimated street value of $1.65 million.

Authorities arrested Akira Garcia Mondragon during the traffic stop. Garcia Mondragon faces felony charges of trafficking fentanyl and possessing a firearm during the commission of a felony.

Sheriff Craig Owens said removing the massive haul from the streets potentially prevented countless tragedies. Owens explained that an amount of fentanyl comparable to a few grains of salt is enough to kill a person.
