Armed with a handgun, Lupoe evidently roamed room to room starting as early as Monday evening, fatally shooting his wife and five young children -- including two sets of twins.
Early Tuesday, Lupoe faxed a bitter, rambling two-page letter to a local television station blaming his employer for his actions. Though his wife and children were already dead, he also called the station threatening to kill his family, investigators believe. He followed this up with an incongruous call to police saying that he had returned home and that "my whole family has been shot."
...Kaiser Permanente confirmed in a statement that Lupoe and his wife, Ana, were recently terminated from employment at the health network's West Los Angeles Medical Center. Hospital officials declined to provide details, saying only that they were cooperating with investigators and "deeply saddened' by the deaths.
