Whitfield County deputies checking on a sex offender found 11 pounds of marijuana and nearly a pound of methamphetamine in the man's home, authorities said.
Deputies were trying to find out where Trinidad Saenz was living. Sex offenders are required to register their addresses with law enforcement.
Saenz was supposed to be living on Hester Circle, but deputies tracked him to Maple Grove Drive. They also heard he was selling drugs.
Narcotics and state probation officers went to Maple Grove Drive on Thursday and searched the home. They said they found drugs valued at $50,000, along with a handgun and more than $7,000 in cash.
His girlfriend's two children were living in the residence, which is a violation of his status of probation as a sex offender, according to a news release.
Saenz, 35, was charged with trafficking in marijuana and methamphetamine; possession of marijuana and methamphetamine with intent to distribute; possession of marijuana and methamphetamine; possession of tools for the commission of a crime; possession of a firearm by a convicted felon, and failure to register as a sex offender.
He is being held without bond.
