A teacher accused of killing two people in a DUI crash could avoid jail time after GBI lab results show she wasn’t under the influence.

Meghan Caldwell, a teacher at Loganville High School, was facing DUI and homicide charges in a March 2016 crash that killed Bradley Atha and Cathy Moore. Her charges have now been reduced to misdemeanors, according to Channel 2 Action News.

The circumstances have drastically changed in what was first called a deadly DUI crash.

Moore,41, and Atha, 36, were killed when Caldwell’s Kia Sorrento collided with their Ford Mustang on Patrick Mill Road in Winder. They died at the scene.

Caldwell had been accused of driving under the influence at the time of the wreck, but her attorney told the news station GBI lab test results, which came back this week, showed she tested negative for alcohol. A breathalyzer test at the time of the crash registered Caldwell positive for alcohol, Channel 2 reported.

Caldwell was originally charged with serious injury by motor vehicle, driving under the influence, two counts of homicide by vehicle in the first degree and a red light violation. Authorities have not said what the news charges are.

The Barrow County District Attorney’s Office has not made the GBI results available, Channel 2 reported, and the chief assistant district attorney will not on comment on the case, citing its pending status.

Moore’s sister Rita Reed said she feels she’s failed her sister.

“I'm failing her now because I'm letting them get away with killing her,” she told Channel 2, “and there's nothing they can do. Or nothing I can do. They could do something if they wanted to.”

Reed said the district attorney told her family no judge would look at the case or sentence Caldwell to jail. The family or their attorney told Channel 2 they have not seen the lab results.
