Tammy Jo Alexander was born in
Atlanta, Georgia, on November 2, 1963, and attended high school in
Brooksville, Florida. Pamela Dyson, Alexander's half-sister, believes that Alexander left to escape a turbulent household. Dyson had a different father from Alexander, and, after about age 11, she lived with her paternal grandmother. According to Dyson, Alexander's biological father was not part of the younger girl's life; she grew up with their mother, Barbara Jenkins, and a stepfather. Their mother had become addicted to prescription medication and was emotionally volatile, erupting into temper tantrums. "She did prescription drugs," Dyson said of Jenkins. "She was
suicidal. I think she had issues back then that they didn't diagnose." Until the identification, Dyson assumed that her half-sister had made a new life somewhere away from her mother and stepfather. She had wished that it included a happy household, with a husband and children. "I thought she just wanted to go away and start all over," Dyson said. With her pockets turned inside out to indicate that any identification she carried had been removed, the investigators later named her "Caledonia Jane Doe" or "Cali Doe" as they worked to identify her. The
autopsy by the medical examiner indicated that Alexander had first been shot in the head while next to the road bordering the cornfield, at or near a blood spot found on the ground. She was dragged into the cornfield, where she was shot again in the back and left for dead. Heavy rains on the night of Alexander's death washed away a large portion of potential
forensic evidence, such as physical and
DNA traces of the perpetrator on her body and clothes. ==Investigation==
