7-Year-Old Girl Shot by Her Mother in Wyoming Murder-Suicide Dies After Five Days in Hospital

After five days of fighting for her life, 7-year-old Olivia Blackmer has tragically passed away following a horrific murder-suicide carried out by her mother, Tranyelle Harshman, in Byron, Wyoming.

Olivia succumbed to her injuries at Primary Children’s Hospital in Salt Lake City on Saturday afternoon, her stepmother, Katelynn Beatty, confirmed.

"Olivia is with her sisters now," Beatty wrote. "She fought so, so hard until the last minute, but her body had been through too much."

On February 10, Harshman, 32, shot and killed Olivia’s 9-year-old sister, Brailey, and her 2-year-old twin stepsisters, Brooke and Jordan, before turning the gun on herself. Olivia was the sole survivor but was critically wounded in the head and later succumbed to her injuries after days in intensive care.

Her grieving father, Quinn Blackmer, shared his devastation on Facebook, writing, "The peace I find is knowing that my babies don’t have to be apart from each other."

Harshman, who had been struggling with mental health issues, including postpartum depression and PTSD, reportedly called 911 before taking her own life, telling dispatchers where authorities would find the children's bodies.

Family and friends continue to mourn the unimaginable loss, while funeral arrangements for Olivia are still being finalized.
