Nichole Gail Clark died Monday at McKay-Dee Hospital Center in Ogden, having never regained consciousness following the freak accident Saturday, The Salt Lake Tribune reported.
Pleasant View police Sgt. Jerry Anderson said he was told by a family member doctors reported the girl had lost brain function.
"I understand the family is planning to remove her from life support sometime later today," Anderson said Monday.
The accident occurred as Clark ran up the stairs of her home with window blinds rod. She fell and the rod pierced her chest, protruding through her neck. She reportedly extracted the rod, which caused more damage, the Tribune said.
Doctors operated to repair the damage, but she did not regain consciousness.
