A family gathering meant to celebrate the memories of loved ones ended in heartbreak when a suspected impaired driver struck a father and his one-year-old daughter at a Sacramento cemetery. Little Janessa Milagro Mazur Diaz, who had celebrated her first birthday just two days earlier, died from her injuries, while her father was rushed to intensive care with severe injuries, including a fractured skull. What should have been a quiet afternoon of remembrance became a nightmare that would forever change one family’s life.

The tragedy unfolded on Sunday, November 1, at St. Mary’s Catholic Cemetery in Sacramento, California, where families had gathered to observe Día de los Muertos, the traditional Day of the Dead celebration. Among those visiting the cemetery were Janessa and her father, who had come to honor the memory of the little girl’s grandmother. Instead of returning home together, their family would soon face a devastating loss that no parent should ever have to endure.

For Janessa’s family, the timing made the tragedy especially painful. The little girl had celebrated her first birthday on Friday, October 30, just two days before the collision. Her family had barely begun imagining the milestones that awaited her when those dreams were suddenly taken away.

A Peaceful Visit Turns Into a Nightmare

According to the Sacramento Police Department, officers responded to the cemetery in the Colonial Village area at approximately 4:45 p.m. after receiving reports that a vehicle had struck two pedestrians. Emergency personnel arrived to find a father and his baby daughter suffering from serious injuries. Both victims were transported to a hospital as medical teams worked urgently to save their lives.

The injuries were devastating. Reports described multiple fractures, including injuries involving the ribs, nose, and skull. Despite emergency medical treatment, little Janessa did not survive, leaving her family struggling to comprehend how an ordinary visit to a cemetery could have ended in such unimaginable loss.

Her father survived the initial collision but remained hospitalized in the intensive care unit, where doctors treated his extensive injuries, including a fractured skull. As his family waited anxiously for updates about his condition, they were also confronted with the heartbreaking responsibility of telling him that his daughter was gone. The emotional weight of that moment was almost impossible to imagine.

A Mother’s Most Heartbreaking Moment

Janessa’s mother, Jackline, spoke to KCRA about the devastation that followed the crash. Her family had been celebrating a precious milestone only days earlier, surrounded by the happiness of their daughter’s first birthday. Suddenly, the joy of that celebration had been replaced by grief, fear, and uncertainty.

Jackline described how the family had simply been enjoying life and celebrating together before everything changed. Nothing about their plans suggested that they were heading toward tragedy. They had gone to remember someone they loved, never expecting to lose another beloved family member that same afternoon.

One of the most painful moments came when Jackline entered her husband’s hospital room and had to tell him that their baby daughter had died. Already suffering from serious physical injuries, he now faced news that no father could ever be prepared to hear. The family was confronting two emergencies at once: the desperate hope that he would recover and the devastating reality that Janessa would never come home.

The little girl had only just turned one. She was at the beginning of her life, with countless birthdays, family celebrations, and childhood memories still ahead of her. Those possibilities were now memories her parents would never have the opportunity to create.

Police Arrest Driver Suspected of Impairment

Sacramento police identified the suspected driver as 50-year-old Miguel Landeros Guzman, who was arrested in connection with the fatal collision. Investigators said the incident was being examined as a suspected impaired-driving crash. Authorities also reported that the driver initially remained at the scene but attempted to leave before officers took him into custody.

According to reported jail records, Guzman was booked into the Sacramento County Main Jail on suspicion of several serious offenses. These included gross vehicular manslaughter while intoxicated, driving under the influence causing bodily injury, felony hit-and-run, and child endangerment. The allegations reflected the seriousness of a collision that had claimed the life of a young child and left her father critically injured.

His bail was reportedly set at $470,000, with an initial court appearance scheduled for Tuesday, November 3. These were allegations and booking offenses reported during the initial investigation, not findings of guilt. The criminal justice process would determine the outcome of the charges and the extent of any legal responsibility.

Investigators continued examining the circumstances surrounding the collision, including the suspected role of alcohol and the driver’s actions before and after the impact. For Janessa’s grieving relatives, however, the legal proceedings could not undo what had happened. Their immediate reality was a hospital room, funeral arrangements, and a home that would never feel the same again.

A Family Asking for Help While Facing Unimaginable Grief

As the family struggled with Janessa’s death and her father’s hospitalization, relatives organized a GoFundMe campaign to help cover funeral expenses, medical bills, and other financial hardships resulting from the tragedy. The fundraiser described the overwhelming emotional pain and uncertainty that had suddenly become part of their everyday lives. Their appeal was not simply about money but about finding enough support to survive a crisis that had shattered their sense of normalcy.

Family members expressed their devastation at losing Janessa so suddenly, explaining that what should have been a peaceful visit had permanently changed their lives. They described their longing to hold her again and the unbearable reality of knowing that such a simple wish could never be fulfilled. Their words reflected the grief of a family trying to honor a little girl’s memory while also caring for her injured father.

The fundraiser also highlighted how quickly a tragedy can create overwhelming financial pressure. Alongside the emotional pain of losing a child, the family faced the costs of funeral arrangements and continuing medical care. Supporters began contributing and sharing the appeal, offering assistance during a period when the family needed both practical help and compassion.

A Birthday Celebration Followed by a Goodbye

Perhaps the most heartbreaking detail is how little time separated Janessa’s first birthday from her death. On October 30, her family celebrated a milestone that represented the beginning of so many more to come. By November 1, they were facing the impossible reality that there would be no second birthday celebration.

For most parents, a child’s first birthday is a moment to reflect on how much their baby has grown and to imagine the years ahead. Janessa’s family had every reason to expect those ordinary joys, from first conversations and school mornings to holidays and family gatherings. Instead, they were left mourning a future that had been taken away.

Her death also cast a painful shadow over the meaning of Día de los Muertos. The family had visited a cemetery to remember a grandmother who had already passed away, participating in a tradition centered on love, remembrance, and family connections across generations. Now, the same family would carry the memory of another loved one whose life had ended far too soon.

Remembering Janessa and the Life She Deserved

The case has renewed attention to the devastating consequences of suspected impaired driving, particularly in places where pedestrians reasonably expect to be safe. A cemetery is somewhere families gather to grieve, reflect, and honor those they have lost. The thought that a child could be fatally struck during such a visit has made this tragedy especially difficult to comprehend.

As the investigation and legal proceedings continue, Janessa’s loved ones are left with questions that may never bring them peace. They must also focus on her father’s recovery, with the knowledge that healing from his physical injuries will be only one part of the journey ahead. Their family has been changed in ways that cannot be measured by medical records or court documents.

Janessa Milagro Mazur Diaz lived only a little more than one year, but her life mattered deeply to those who loved her. She deserved a childhood filled with laughter, affection, celebrations, and the opportunity to grow into the person she might have become. Her family now faces the painful task of preserving her memory while learning to live with her absence.

A mother should never have to tell her injured husband that their baby is gone. A father should never have to wake in a hospital and discover that the daughter he was visiting a loved one’s grave with will never return home. And a family that gathered to honor the dead should never have been forced to begin mourning another life that same day.

Rest in peace, sweet Janessa Milagro Mazur Diaz. Your life was brief, but the love surrounding you will endure. May your father find strength and healing, and may your family receive the compassion and support they need.
