October 4, 1989

October 4, 1989, is the date on which a hundred wild monkeys reached the Reston Primate Quarantine Unit and John Jaax was killed in Kansas City. These separate events give the day its particular weight: the first begins a deadly sequence at a commercial quarantine facility, while the second devastates Jerry Jaax and leaves his family facing an unsolved murder.

Arrival at the Reston monkey house

On October 4, Hazleton Research Products accepted a shipment of a hundred wild monkeys at its one-story Reston facility. The animals came from coastal rain forests on Mindanao in the Philippines. After being shipped by boat to the Ferlite Farms monkey holding facility near Manila, they were grouped in large cages, crated, flown to Amsterdam and then New York City, and trucked south to Reston. They were crab-eating macaques, imported as laboratory animals and held in quarantine before distribution.

Two monkeys were already dead in their crates when the shipment arrived, a loss the account describes as not unusual during transport. The more alarming change came over the next three weeks, when an unusual number of monkeys began dying at the facility. The date therefore stands at the beginning of an outbreak chronology, though the deaths on October 4 alone did not yet make the danger apparent.

John Jaax's killing

That same day, John Jaax planned to attend a parent-teacher meeting with his wife. Near the end of the workday, he called from the manufacturing plant to say he would be working late and would go directly to the meeting. When he failed to arrive, his wife went to the factory and found him dead in his office. The account establishes no connection between his killing and the events in Reston; their concurrence is a narrative juxtaposition, not a causal link.

John was Jerry Jaax's younger brother. The two had grown up together on a Kansas farm, attended Kansas State, and were described as exceptionally close; they also resembled one another in appearance and voice. John was a businessman and banker, and a partner in a company that manufactured plastic for credit cards. Police considered his business partner a suspect, but he had an alibi, and the investigation found few physical clues. The case remained unsolved.

Consequences and narrative significance

John's death left Jerry in profound grief. During October and November, he called Kansas City Homicide nearly every day as investigators failed to solve the case. He also considered going to Kansas City and killing John's business partner, but the account presents this as a thought born of grief, not as an action he took. The loss changed the emotional landscape of Jerry's life even as the investigation stalled.

By placing the monkey shipment and the killing on the same date, the narrative makes October 4 a hinge between two storylines: an outbreak whose significance would emerge over the following weeks and a bereavement whose consequences were immediate and lasting. The two developments remain independent, but their shared date brings the widening danger at Reston into the same frame as Jerry's private catastrophe.
