Pamela Gail Clark, 42, was murdered in her University City home in San Diego on September 13, 1990. She left early that morning to visit the Family Fitness Center on Miramar Road; her husband left shortly after and their 18-year-old daughter Amber Clark was still in bed. A neighbor later heard Amber speaking with someone inside the house and then a male voice; Amber cried out but the disturbance did not escalate in the neighbor’s hearing.

Pamela returned home around 11:00 AM but did not go to work; a colleague who checked the house found Pamela’s body in the entryway. She was nude, arms spread at 90-degree angles, and had eleven deep stab wounds to her upper left chest. Blood trails indicated she had been attacked elsewhere and dragged to that spot; a bloody knife lay near her head.

Investigators found the screen removed from a dining room window, shoe prints beneath that window, marks on a sliding door indicating attempted forced entry, Pamela’s wedding ring missing, and money taken from her purse though robbery did not appear to be the primary motive. Did anyone in the community know whether Pamela or Amber had reported being followed or threatened before September 13, 1990?
