Snipped:
Wake County Child Protective Services had no prior complaints about Teghan's welfare. It began investigating after Teghan was rushed to the hospital, when Johnston County Social Services determined Teghan and her mother had been living in Raleigh with Reyes' mother. Reyes and Teghan had gone to live with Richardson in the barn four weeks before Reyes left for military training, according to Ludwig.
