Robert Lynn Manley Jr., a 31-year-old cabinetmaker known as Bob, was last seen at his Phoenix apartment near 9th Avenue and Indian School Road on October 9, 1990. He was scheduled to drive to El Centro, California, for a work installation but never arrived. His pickup was found at the complex with his luggage and tools packed for the trip; his keys and wallet remained locked inside his apartment. Investigators found signs in the apartment consistent with a violent struggle.

Attention turned to John Kennard Ingersoll after police learned he suspected Manley of having an affair with his wife. Blood was found in the back of Ingersoll’s pickup. In 1992 Ingersoll was arrested, charged with kidnapping and first-degree murder, and later convicted; prosecutors said he shot Manley and buried him in the desert. Manley’s body has never been recovered and the case is officially treated as a presumed homicide.

Did anyone who knew Robert or worked with him in Phoenix or El Centro notice unusual activity around October 1990 or have information about his planned trip?
