A couple arrested after some of their adopted children were found locked in a shed at their West Virginia home are set for trial later this year on charges that a judge said involved their use as “slaves.” Donald Ray Lantz and Jeanne Kay Whitefeather face trial later this year after they were arraigned on 16 counts each accusing them of civil rights violations, human trafficking, forced labor, gross child neglect and falsifying an application seeking a public defender. All but one of the counts are felonies.
