Tranyelle Harshman, 32, from Wyoming, opened fire at her children, aged between 2 and 9, and left one of her daughters in intensive care following the horrific shooting inside their home in Byron, Wyoming, according to police.
Three children, two aged 2, and one aged 9, named as Brailey, died in the shooting as a 7-year-old girl, named as Olivia, was left fighting for her life with a 'severe traumatic brain injury'.
Harshman shares two children with husband Cliff, who is dad to the two younger girls, and the two older kids with ex-husband Quinn Blackmer.
Officers were called to the home following reports of gunshots in the home after a woman, believed to be Harshman, called police to say "her daughters had been shot.".
Cliff Harshman, a devoted husband and father of four beautiful daughters, has suffered an unimaginable loss: the passing of 3 of his precious girls.
