A grieving father shared his heartbreak after losing his 7-year-old daughter, Olivia Blackmer, who died following brain surgery after a tragic murder-suicide.

Olivia’s mother, Tranyelle Harshman, 32, SH0T and kiIIed Olivia’s three sisters—Brailey, 9, Brooke, 3, and Jordan, 2—before turning the gun on herself. Olivia fought for five days in the hospital but passed away.

“Olivia is with her sisters now,” the family wrote in a GoFundMe post, adding that medical options were exhausted.

Harshman, who suffered from PTSD and postpartum depression, alerted police before the tragedy and died a day later. Olivia’s father, Quinn Blackmer, expressed his sorrow, finding comfort in knowing his daughters are together.
