In January 2022, the Texas lab, Othram, conducted tests using DNA. The tests were made possible by donations. In May 2022, Othram discovered that a man, David Meyer, could be the Christmas Tree Lady's brother. After David Meyer looked at the drawing of the Christmas Tree Lady, he was unable to say whether or not she was his sister because the last time he saw her was decades ago. The detectives were then told to go to his sister, Clough. After seeing the drawing, Clough said that she was definitely Joyce. DNA was taken from Clough, and the Christmas Tree Lady was identified as Sommers. Detectives were unable to find any connection between Sommers and any of the graves. Clough believed that her sister never bore children despite a large scar across her stomach which possibly indicated a Caesarean section.
