 In August of 1995, when Dr. G worked in Bexar County, Texas, a pile of human bones was found at a supposedly haunted railroad crossing. Dr. G could tell that the victim was a teenager, but could not determine the sex. A DNA test said that the victim was male, but a 12-year-old girl told authorities that the bones were her sister s and that her sister had been murdered by her abusive mother. Her claim was unable to be verified and the authorities thought she was lying. The case went unsolved. Two years later, Dr. G found that the skull matched that of the girl reported missing, but why did the DNA test come back male, and how will that affect the case against the girl s mother? A 53-year-old man doesn t show up for work, and is found dead in his apartment. A neighbor says that the man was weak and dizzy the night before. Could the man s obesity have played a role in his death?
