About the Tracers Series

In 2004, seventeen-year-old Vanessa Hayley Jones, heiress to one of the largest oil fortunes in Texas, laced up her running shoes and went for out for a jog. She never came home.

Two days later, her brutalized body was discovered in Houston’s Memorial Park. Six weeks later, police arrested twenty-six-year-old Wayne Korbin, a previously convicted sex offender, and charged him with Vanessa’s rape and murder. At trial, Vanessa’s widowed mother looked on as prosecutors showed jurors how Korbin’s DNA matched samples taken from her daughter’s body. Korbin was sentenced to life in prison.

Five years later, a technician at the state crime lab entered into the national database a DNA profile from a decade-old rape kit. He got a hit: Wayne Korbin. Six months later, another technician got a hit with another previously untested rape kit: Korbin again. To date, DNA evidence taken from six separate rape kits have been found to match the genetic profile of Wayne Korbin. If even one of those rape kits had been processed in a timely manner, Vanessa Hayley Jones might be alive today.

Several years ago, Vanessa’s mother gave away the bulk of the Hayley family oil fortune. Her purpose: to establish a cutting edge forensics laboratory known as the Delphi Center. The Delphi Center is founded on the premise that the best predictor of future violent behavior is past violent behavior. Scientists at the Delphi Center are on a mission to help the criminal justice system catch up to the astonishing capabilities of forensic science. The center is staffed by a group of investigators known as The Tracers.

The Tracers: An elite cadre of forensic investigators who use trace–often microscopic–evidence to solve crimes. Detectives look to the Tracers for help when traditional law enforcement agencies aren’t up to the job. Mia Voss and other Tracers at the Delphi Center use cutting-edge forensic techniques to help their clients unravel even the most confounding mysteries.
