Homicide Detective Theo Mazur parked on the side of I-35, twenty miles outside of San Antonio, behind the forensic van and the collection of Bexar County cop and rescue vehicles. Flares had closed the two southbound lanes, and a deputy was directing snarled traffic toward the access road that ran parallel to the highway. The morning sun cast a warm glow over the endless miles of brush, low prickly trees, and red dirt.
