The father of the seven-year-old girl, who tragically died from a gunshot wound inflicted by her mother in a murder-suicide, has spoken out following her passing.

Olivia Blackmer passed away on Saturday afternoon (February 15), five days after being rushed to the hospital with a gunshot wound to her head, caused by her mother, Tranyelle Harshman.

After making a 911 call, Harshman, 32, shot Olivia and her sisters before turning the gun on herself. She later succumbed to her injuries in the hospital.

Olivia’s 9-year-old sister, Brailey, along with her two-year-old stepsisters, Brooke and Jordan, tragically died on February 10 at the crime scene in Wyoming.

Olivia, though critically injured, was initially taken to a local hospital and then airlifted to a specialized facility for further care. Her father, Quinn Blackmer, confirmed her death and shared an emotional message on Facebook, expressing his heartbreak after losing his young daughter (via PEOPLE).

He wrote: “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.

“Funeral arrangements and updates to what we think the world needs to know will be on my Facebook but will also be on the GoFundMe.

“Speaking of that, from the bottom of our hearts we want to thank every single person that has donated and prayed and fasted for us and our family and our beautiful Olivia.

“Your kindness and generosity has been so much and we just ask that you continue to pray and keep us all in your thoughts.
