A man who was storing drugs at his mother’s home will spend 13 years in prison, Cobb County officials said Wednesday.

Mark Sheldon Fairchild, 26, was convicted on 24 charges, including trafficking heroin and possession of cocaine and marijuana with intent to distribute, Cobb County District Attorney spokeswoman Kimberly Isaza said in a news release.

Fairchild will serve the remaining 27 years on probation following his prison sentence.

“Although we must seek treatment-driven alternatives to those addicted to heroin, the traffickers must be held accountable and punished for providing this poison to our community,” Cobb County District Attorney Vic Reynolds said in the release.

In October 2014, Marietta police got a tip about Fairchild’s drug activity and set up surveillance near his home. Officers stopped Fairchild for a traffic violation and saw him eating marijuana.

Fairchild told police there were more drugs at his home, but to not file any charges against his family, Isaza said. Officers were allowed to enter the home, but Fairchild’s mother stopped them from entering her son’s bedroom when they smelled marijuana.

Through a search warrant, officers found 41 grams of heroin, nine grams of cocaine and more than four ounces of marijuana, the release said. They also found $450 in cash, fish food, which is used to cut heroin, hundreds of baggies, a scale and other drug paraphernalia.

The Georgia Bureau of Investigation Crime Lab said the bust was in the top 10 percent of heroin cases they’ve worked.

“Forty grams of heroin can be broken into 400 individual hits, going to 400 people on the streets of Cobb County,” Cobb Assistant District Attorney Richele Anderson said in the release.
