Fourth daughter dies after tragic alleged murder-suicide by mother

A heartbreaking update has emerged from Wyoming, as 7-year-old Olivia Blackmer has passed away days after surviving an apparent murder-suicide carried out by her mother, Tranyelle Harshman.

Olivia had been the sole survivor after Harshman allegedly shot her four daughters before turning the gun on herself on February 10, 2025. The attack claimed the lives of 9-year-old Brailey Blackmer, 2-year-old twins Brooke and Jordan Harshman, and their mother, Tranyelle. Olivia was airlifted to a hospital in Salt Lake City, where people worldwide prayed for her recovery.

Tragically, her father, Quinn Blackmer, confirmed on Facebook that Olivia passed away on February 15.

A father’s grief: “Absolutely gutted”

In his emotional post, Quinn Blackmer shared the devastating news with the world.

“I know this isn’t the update people were hoping for and we are absolutely gutted to make it, but we needed time to process what had happened before we let the world know of the tragic passing of Olivia yesterday (February 15) afternoon at 3:44 pm,” he wrote.

He asked for privacy as the families involved navigate their unimaginable loss.

“The amount of devastation we feel and are going through is so much. Please give all families involved our time and space during this extremely difficult time in our life.”

Despite the grief, Quinn found a small measure of comfort in knowing his daughters were together.

“The peace I find is knowing that my babies don’t have to be apart from each other and they can also be with their other sisters,” he added.

A mother’s struggle with mental illness

According to reports, 32-year-old Tranyelle Harshman had been battling postpartum depression, post-traumatic stress disorder, and severe depression. On the day of the tragedy, she reportedly called 911 to confess to shooting her daughters, warning that she intended to take her own life as well.

Her husband, Cliff Harshman, spoke to Cowboy State Daily about her struggles, emphasizing that she was not a “monster” but someone suffering from serious mental health conditions.

“Most people don’t understand how that affects the brain. It’s a chemical imbalance. And it can be exacerbated by trying to fix it with medication,” Cliff explained.

A heartbreaking reminder of the importance of mental health support

This tragedy has sparked renewed conversations about the impact of postpartum depression and the need for greater mental health awareness and support for struggling parents.

As the community mourns, many are calling for better resources to prevent similar tragedies in the future. Mental health professionals stress the importance of seeking help and checking in on loved ones who may be struggling.

For now, the world mourns the loss of four innocent children taken far too soon.

Rest in peace, Brailey, Brooke, Jordan, and Olivia. 💔
