Za’Zell Preston was 26 years old, seven weeks postpartum, and studying to become a domestic violence counselor when her husband, William Wallace, beat her to death in their Anaheim, California apartment on Christmas Eve, 2011.
By every measure available to the systems meant to protect her, Preston’s danger was not hidden. Police had been called to the couple’s home more than a dozen times for domestic violence incidents before that night. Wallace had already served jail time for a prior assault against her. He had made repeated threats to kill her. None of it stopped what happened next.
The morning after her death, Wallace moved her body from the bedroom to the living room couch, placed sunglasses over her eyes, and told the couple’s three young children — ages seven weeks, three, and eight — that their mother had “ruined Christmas” by getting drunk. The children opened their presents that morning beside her body. One of Preston’s daughters later testified in court that she touched her mother’s arm and said “Mommy,” and her mother did not respond, because she was, in the child’s words, “rock hard, cold.”
Wallace was convicted of second-degree murder in April 2021 — nearly a decade after the killing — and sentenced to 15 years to life in prison. At sentencing, Preston’s mother told the court that Wallace had “beat and tortured my daughter and at the same time mentally assassinated her children.”
We are choosing to tell this story not as a crime headline, but as a warning that deserves to be understood.
A pattern that is rarely invisible
One of the most painful facts of this case is how visible the danger was before Preston died. More than a dozen police calls to one address is not a private matter that escalated without warning — it is a documented pattern that advocates and researchers say is common in cases that end in homicide. According to the National Domestic Violence Hotline and organizations that study intimate partner violence, repeated police contact, prior convictions for abuse, and direct threats to kill are all recognized high-risk indicators. Preston’s case had all three.
This is not written to assign blame to any single officer, agency, or decision made in 2011. It is written because the pattern itself is the lesson. Domestic violence rarely erupts without warning signs. It escalates — often in ways that are visible to neighbors, family, coworkers, and, as in this case, to the police who are called again and again.
The children who were there
Perhaps the detail of this case that is hardest to read is also the one advocates say matters most: children in violent homes are rarely as protected from what happens as adults hope. Preston’s three children were in the apartment. Her eight-year-old daughter testified in court years later about touching her mother’s cold arm on Christmas morning. Child welfare and trauma researchers have long noted that children who witness domestic violence, even when they are very young, can carry the effects of that exposure for years — a reality that adds another layer of urgency to early intervention, before a household reaches a breaking point.
Why this story is being told now
Preston was training to help other people escape the exact kind of violence that ended her life. That fact alone is worth sitting with. It is a reminder that recognizing danger in someone else’s relationship is often far easier than recognizing it, or acting on it, in one’s own — and that the systems meant to intervene do not always move fast enough or far enough to prevent the worst outcome.
Telling her story is not about dwelling on how she died. It’s about making sure her name, her plans, and the warning signs that preceded her death are not forgotten — and that anyone reading this who recognizes a similar pattern, in their own life or someone else’s, knows that help exists and that reaching out is worth it.
