Eldon Mate—Guillerma Salcido Mate

The relationship between Eldon Mate and Guillerma Salcido Mate was defined by an early marriage, Mate’s departure after the birth of their son, and a quarter-century of estrangement softened only by monthly payments. When Mate died, Guillerma returned to claim her place as his widow, but not his surname or his public cause: she regarded his assisted killings as sinful and his fame as a source of shame.

Marriage and Separation

Guillerma established the marriage with a Social Security card and a worn photocopy of the marriage license. The license, issued in San Diego twenty-seven years before the interview, made the history tangible: its faded lettering recorded a union that had long since ceased to function as a partnership. Guillerma said she had last seen Mate twenty-five years and four months earlier, shortly after their son was born.

Mate had told Guillerma from the beginning that he did not like children. She believed that having a child of his own might change his mind, but when she became pregnant, he left. The separation was not followed by a sustained effort to share family life. Years later, when Mate was working at a hospital in Oakland, Guillerma took Donny there, hoping to reunite the boy with his father. The visit instead confirmed the rupture: Mate would not speak to Donny or pick him up, and when the child became frightened by his father’s white coat and screamed, Mate became angry and ordered Guillerma to take him away.

A Family Life Imagined, Then Refused

Before that rejection, Guillerma had imagined a future shaped around Mate’s education and her own ambitions. She planned to become a registered nurse and pictured Mate opening a medical office where she could work beside him. After he left her and refused Donny, she had to keep working and never finished school. She later described herself as doing much of the work nurses do while caring for elderly people at a convalescent home, but the career she had pictured with Mate did not materialize.

The couple’s separation did not lead Guillerma to build another intimate relationship. She said there was no other man she wanted to know, and that she did not make a move toward a new life. She remained in Oakland with Donny, while Mate’s connection to them narrowed to money. Her account therefore distinguishes the practical continuity of support from the emotional and parental relationship that had ended: a payment could arrive on schedule without bringing its sender back into the family.

Money, Habit, and Silence

Guillerma described Mate’s monthly remittances as five hundred dollars, usually sent by money order, and resisted calling that amount full support because she had always worked. Still, the payments came reliably. At the time she spoke with Milo Sturgis, the latest payment was five days late; she understood it to be an Army Reserve pension and asked how to arrange for it to be sent directly to her. Milo offered to find a contact number. The practical question exposed the narrow channel through which the estranged couple had remained connected: the routine survived Mate, but his death interrupted it.

For years, Guillerma had interpreted the payments as a possible expression of guilt over his leaving. By the time she recounted the history, she doubted that explanation. She saw Mate instead as a man governed by habits, pointing to his regular payments to his mother in place of visits, and to his preference for wearing one color of shirt and one color of pants because, as she recalled, it left time for important things. They did not communicate during the long separation; the money was the enduring act, but it did not amount to reconciliation.

The Widow and the Public Doctor

Guillerma traveled by Greyhound from Oakland after hearing that Mate had died. She worked caring for the elderly and was unsure at first whether she should come, since so many years had passed. At the duplex, she said she no longer used Mate’s name but remained his wife and widow. She had never been to that part of the city, got lost on a bus, and found streets torn up; her unfamiliarity with the place underscored how little of Mate’s later life she had shared.

Her distance became deliberate after she saw Mate on television discussing his killing work. She had not seen him for years; he looked older and balder, but she recognized the same face and voice. She remembered him as boasting about what he had done, concluded that he had gone completely mad, and changed her name back to Salcido on her Social Security records and elsewhere. She called the killing disgusting and a mortal sin, and said she kept the marriage quiet among church acquaintances because it embarrassed her. Friends urged her to consult a lawyer for more money from the now-wealthy Mate, but she regarded that prospect as sinful money. At his death she asked whether he had left a will; none had been found, and she anticipated the difficulty of probate even as she asserted her widowhood.

Care, Faith, and the Unresolved Bond

Guillerma’s moral judgment was grounded in a religious outlook and memories of suffering. She recalled that her mother had taught her that the world beyond this life mattered most and that the way there was through Jesus. Her father had been an unbeliever until he was dying of lung cancer, which had spread to his bones and spine; his painful death made a deep impression on Mate. Guillerma’s memory supplies a personal context for Mate’s later engagement with death, but it does not settle the difference between compassionate intent and the publicity-seeking violence she believed she saw in him.

That distinction also troubled Alex Delaware, who had served on a hospital committee considering when to end treatment for children with terminal illnesses. He remembered cases in which a slightly larger dose of morphine preceded a child’s death after the parents had said goodbye, and understood such acts as an effort to spare suffering. He nevertheless questioned why Mate’s use of the Humanitron felt different, suspecting his motives and recoiling from his apparent gloating. Guillerma’s testimony adds the intimate cost of Mate’s public identity: the wife he had left did not share his cause, and his fame reached her as something to disavow. Their relationship ended neither in renewed contact nor in a final conversation, but in her journey to claim the status of widow while separating herself from the name and work by which he had become known.
