A western Oklahoma couple and several of their businesses face a second lawsuit alleging human trafficking of immigrants who were in the United States on work visas.

The lawsuit filed in June by three Jamaican immigrants comes after a similar lawsuit was filed in July 2017 by three Filipino immigrants.

Both lawsuits allege husband and wife Walter Schumacher and Carolyn Schumacher of Clinton, about 80 miles (128 kilometers) west of Oklahoma City, lured the workers with promises of good wages and free or low-cost housing, but instead used them as cheap labor and charged them high costs for housing.

An attorney for the Schumachers did not return a phone call seeking comment, but previously denied the allegations and described the couple as "heartsick."
