On Nov. 3, 1972, Frederich H. Cassel began to complain of chest congestion. He was admitted to the hospital on November 9 of that year, and, after feeling better, he was released on Nov. 30. Cassel was then readmitted to the hospital on Dec. 8, 1972, complaining of shortness of breath and chest congestion. He died in the hospital on Dec. 11, 1972.
An autopsy was performed, and the toxicology report determined that Cassel had been poisoned. Cassel, who lived in the Applewood area and worked in General Service Administration at the Federal Center in Lakewood, had worked in San Francisco and Washington, D.C., and he had top secret security clearance. Before his death, Cassel talked with fellow employees about unusual things happening in his life, and he recorded them in a diary.
