LOS ANGELES (AP) — A Southern California couple who were held in Qatar for nearly two years before they were cleared in the death of their 8-year-old daughter have sued the engineering firm that sent them overseas.

The Los Angeles Times reports that Matt and Grace Huang filed the negligence and wrongful termination suit against MWH Global on Monday.

The lawsuit claims the Colorado-based company failed to provide security or cultural training and fired Matt Huang.

The Huangs were arrested in January 2013 on charges of starving their African-born adopted daughter, Gloria. They spent nearly a year in jail. Their child endangerment convictions were overturned and they were allowed to leave Qatar last week.

MWH says it checked on the family's welfare and spent hundreds of thousands of dollars on Matt Huang's defense. It also says Huang resigned.
