The situation began in July, when Melissa Bright let her two kids play in the sprinkler outside on a hot summer day. She put 5-month-old Mason on a lawn chair while she helped Charlotte, 2, remove her wet clothes, but then heard a thud; Mason had fallen 19 inches onto the driveway. Medical treatment revealed that Mason Bright had bleeding in his brain as well as two fractures, one of which the hospital’s child-abuse team determined was not due to the fall. When Melissa couldn’t offer an explanation, the team decided the injury was “consistent with child abuse.” In the meantime, the Chronicle said, hospital staff found that the baby had a blood clotting disorder that could have contributed to the severity of his injuries. A CPS supervisor ruled that the couple’s children would have to live with Dillon Bright’s mother, who lived more than an hour away. But Mason’s injuries, which required extensive nursing, were more than his grandmother could handle, and the Brights requested that the baby be moved to another relative’s house in Tomball, which was closer. When CPS took too long to respond, Dillon told the agency the couple planned to bring the children back home, which they did. Three weeks later, on Sept. 18, a caseworker texted to ask how the kids were, and Melissa sent photos and an update indicating all was well.
