The family of a Michigan girl killed in a tragic ATV accident – that also left her 14-year-old sister severely injured – said that she will have the chance to save six others since they have decided to donate her organs.

“I think the hardest thing we did was signing the paper for organ donation,” Larry Robinson, the girls’ father, told Fox 2 Detroit. “I don’t get our daughter back but there are six families that get a little more time to spend with their loved ones.”

Riley Robinson, 12, and her sister Peyton, had taken off on the recreational vehicles near their grandmother’s property in Missaukee County on Sept. 9, Fox 2 Detroit reported.

Robinson said the pair often went riding, but at around 10 a.m., one of them lost control of the vehicle and crashed into trees. The girls’ 16-year-old brother, Tyler, found them and dialed 911. Robinson said the teen pulled the 4-wheeler off of his sister, and “did everything he could.”
