A Tragic End: 7-Year-Old Olivia Blackmer Passes Away After Wyoming Murder-Suicide

What was already an unimaginable tragedy has grown even darker. Seven-year-old Olivia Blackmer, the last surviving child in a devastating family murder-suicide, has succumbed to her injuries, leaving the Wyoming community of Byron heartbroken.

Her mother, 32-year-old Tranyelle Harshman, had fatally shot Olivia’s three younger sisters—Brailey, 9, and 2-year-old twins Brooke and Jordan—before turning the gun on herself. Olivia was the only one still clinging to life in the immediate aftermath, but despite a valiant fight, she passed away on February 15, 2025, just five days after the tragic incident.

The Horrific Night That Changed Everything

On February 10, 2025, around 2:00 AM, Harshman called 911, her voice trembling. “It’s too late,” she reportedly whispered to the dispatcher. The operator tried to keep her on the line, but she soon fell silent.

When first responders arrived at the home, they discovered a gruesome scene—three of the four children were already dead. Olivia, miraculously still alive despite being shot in the head, was rushed via helicopter to Primary Children’s Hospital in Salt Lake City, Utah.

Her mother, who had also survived the initial gunshot, was transported to a nearby hospital, but she died the following day, February 11.

Meanwhile, Olivia remained in critical condition, surrounded by doctors and loved ones praying for a miracle.

For days, family, friends, and supporters worldwide followed updates on her condition, hoping she would pull through. Her father, Quinn Blackmer, and other family members clung to the small chance of survival.

Sadly, on February 15, Olivia’s fight ended. Her father and relatives confirmed her passing in a heartfelt statement:

“She gained her angel wings. She fought so hard, but her body couldn’t recover.”

The Family’s Shocking Despair

The tragedy has left an entire family and community in disbelief.

Olivia’s father, Quinn, spoke through grief, anger, and disbelief.

“I’m so angry with her for the decision that was made,” he admitted. “I don’t understand it. I don’t think I ever will.”

Despite his heartbreak, he also shared that Tranyelle’s actions were completely out of character.

“We knew she was struggling, and we tried to help her. We sought medical treatment, therapy… but something didn’t work.”

Quinn desperately wants people to remember the mother his children loved, not just the act that took their lives. He believes that mental illness played a crucial role in the devastating events.

A Mother’s Secret Battle with Mental Illness

Those close to Tranyelle Harshman revealed that she battled severe postpartum depression and possibly undiagnosed PTSD.

“She was always a loving mom,” a family friend said. “She was struggling, yes, but none of us saw this coming.”

Tranyelle’s mental health had declined in the months leading up to the shooting, with reports indicating she had been in and out of treatment but was still grappling with dark thoughts.

Mental health advocates have urged the public to show compassion rather than just anger, recognizing how untreated or improperly managed depression can have catastrophic consequences.

“This is not about making excuses,” said a spokesperson for a local women’s crisis center. “It’s about making sure that something like this never happens again.”

Byron, Wyoming: A Town in Mourning

Byron is a small town of about 600 residents in Wyoming’s Big Horn County. It’s the kind of place where everyone knows everyone, which makes this tragedy all the more painful.

Local schools held memorials for Brailey and Olivia, who were both beloved by classmates and teachers.

A candlelight vigil was held on February 16, where hundreds of community members gathered to honor the children’s lives.

“You could just feel the sorrow,” said one attendee. “This town is broken.”

The Investigation and Theories Behind the Tragedy

Law enforcement officials continue to investigate what led to the shocking event.

Although no official motive has been released, those close to Tranyelle believe that a severe mental health crisis played a role.

“She wasn’t a violent person,” an anonymous friend said. “This wasn’t her.”

Authorities confirmed that the firearm used in the killings was legally obtained. However, questions remain about how and when she made the decision to carry out such a horrific act.

The Financial Toll: GoFundMe Raises Over $108,000

As the family mourns, they are also dealing with overwhelming funeral and medical costs.

A GoFundMe campaign, set up to assist Quinn Blackmer and cover the funeral expenses, has raised over $108,000 so far.

The funds will help with:

• Medical bills from Olivia’s hospitalization
• Funeral costs for all four daughters
• Grief counseling for the surviving family members
• Support for Quinn, who lost everything

“This money won’t bring them back, but it can help us find a way forward,” Quinn said.

Funeral Plans and Saying Goodbye

Funeral services for Brailey, Brooke, Jordan, and Olivia are being arranged, with details expected soon.

The family is planning a joint memorial service, allowing loved ones to honor the four sisters together.

“Our girls deserve to be remembered for their smiles, their laughter, and the joy they brought into the world,” Quinn said.

A Call to Action: Addressing Mental Health

This tragedy has sparked national discussions about the importance of mental health care for mothers.

Mental health advocates are urging families to take postpartum depression seriously.

“This isn’t something that only happens in other places,” one counselor said. “It’s happening in our communities, and we need to provide resources for struggling parents.”

Organizations like Postpartum Support International and the National Alliance on Mental Illness (NAMI) are urging people to look out for warning signs in loved ones and seek immediate help when needed.
