The U.S. ambassador to Qatar says that an American couple cleared of charges in their adopted daughter's death have left the Gulf Arab nation.

Matthew and Grace Huang's departure on Wednesday closes a nearly two-year saga that climaxed in a court ruling absolving them of any wrongdoing in the death of their 8-year-old daughter Gloria.

U.S. Ambassador to Qatar Dana Shell Smith wrote on Twitter that "Matt and Grace Huang are wheels up from Qatar."

She describes the moment as "emotional." The couple will be reunited with their other children in Los Angeles.

The Huangs were arrested in January 2013 on murder charges following the death in Qatar of Gloria, who was born in Ghana.

A Qatari appeals court overturned charges against them on Sunday.
