Six people were charged in a drug investigation that led officers to more than $20,000 worth of drugs, according to authorities.

Multi-Agency Narcotics Squad agents searched two locations on Ralston and Johnson streets Monday.

On Ralston Street, authorities said four suspects “were found to be in possession of approximately 30 grams of heroin, 34 grams of methamphetamine, 16 grams of cocaine, (4.5) ounces of marijuana, digital scales and packaging materials.”

MANS Lt. Don Scalia said four firearms were found, and two of those had altered or obliterated serial numbers.

“During the investigation at the Johnson Street location, Mr. (Ignacio DeJesus) Sanchez-Hernandez fled to a bathroom upon contact with law enforcement and flushed a quantity of methamphetamine in a toilet in an attempt to destroy evidence,” Scalia wrote in a news release.

Sanchez-Hernandez, 22, of Gainesville, was charged with possession of methamphetamine and tampering with evidence.

Scalia said MANS agents seized $20,309 in cash in addition to the $20,840 worth of narcotics found.

All of the suspects were booked in to the Hall County Jail, where they remain.

Hau Nguyen, 30, Jose Juan Trejo-Mendoza, 21, both of Gainesville, and Reina Trejo-Reyes, 32, of Chamblee, were charged with trafficking and possessing heroin and methamphetamine with the intent to distribute. The three were also charged with possessing cocaine and marijuana with the intent to distribute and possession of a firearm with an altered ID mark.

Scalia said Kim Xuyen Tran, 60, of Gainesville, was charged with conspiracy to commit the crimes listed for Nguyen, Trejo-Mendoza and Trejo-Reyes.

Artemio Gonzales-Solorzano, 39, of Gainesville, was charged with possession of cocaine and methamphetamine.
