Seven-year-old Olivia Blackmer died on February 15, five days after being shot in the head by her mother, Tranyelle Harshman, in a murder-suicide. Harshman, 32, called 911 before fatally shooting Olivia’s sisters—Brailey, 9, and two-year-old twins, Brooke and Jordan—before turning the gun on herself. Olivia was taken to the hospital but succumbed to her injuries.

Olivia’s father, Quinn Blackmer, shared his grief on Facebook, writing, “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.” He also thanked those who donated and prayed, adding, “The peace I find is knowing that my babies don’t have to be apart from each other.”

Olivia’s stepmother, Katelynn Blackmer, announced her passing on GoFundMe: “She gained her angel wings yesterday at 3:44 pm. She fought so hard up till the last minute.” She expressed gratitude for the support, saying, “We are in a rough spot with the tragic passing of both daughters.”
