A teacher at a local middle school has resigned after she and another woman were arrested during a $6 million drug bust in Hall County.

Karla Alvarez’s resignation was approved by the Hall County Board of Education on Monday.

She was on unpaid leave from her job as a teacher at Chestatee Academy in Gainesville, The Atlanta Journal-Constitution previously reported.

Alvarez, 28, and Monica Pascual-Brito, 24, were arrested March 21 at their home on Crawford Oaks Drive in Oakwood.

Deputies said they found 61 kilograms of cocaine, one kilogram of heroin and two semi-automatic assault rifles during their search of the home.

“The quantity is pretty substantial,” Hall County sheriff’s Lt. Scott Ware said. “We have arrested teachers before, but I don’t recall arresting a teacher with this amount of drugs.”

The middle school teacher was one of two people arrested in the case.
