Ann Tomoko was not a 21-year-old woman, as some secondary sites claim, but a four-month-old female infant who died in Wahiawa, Hawaii, on August 9, 1960, in a case that unfolded inside a small apartment and shattered an entire family in a single afternoon. Contemporary reporting identified the dead as Ann, her mother Tomoko Katori Tatsuno, 25, her sister Margie, 14 months old, and Jack Warden, 35, of Atlanta. Albert Tatsuno, a Schofield Barracks soldier and the husband and father in the household, reportedly came home around 3:50 p.m. and found the door locked, only to discover the horror inside.
The picture that emerged was not of an unknown attacker drifting through Wahiawa, but of a deeply personal and violent intrusion. Later summaries of the case, drawn from Hawaii newspaper reporting, said Jack Crawford Warden was Tomoko Tatsuno's former girlfriend's boyfriend—more precisely, her former sweetheart—and that he shot and killed Tomoko and her two young children before turning the gun on himself. One archival account also pointed to an unmailed letter and to the husband's statement that he had believed Warden had been in California shortly before the killings, suggesting there had been concern or uncertainty about Warden's whereabouts before the attack. The tragedy therefore appears to have been a murder-suicide rooted in a prior relationship, not a random crime.
Because Warden died at the scene, there was no arrest in the ordinary sense, no prosecution, and no trial that could end in conviction. The available online record instead preserves the case as a grim domestic mass killing: a former lover arriving at the apartment, a mother and her two little girls dead before the day was over, and a husband returning home to a silence that gave way to one of Wahiawa's most haunting crime scenes. In the historical record that survives online, Warden stands as the sole identified suspect, and the case effectively closed with his death.
