A 16-year-old Eagle girl died Tuesday from injuries suffered in a two-car crash on Highway 16 last week.

The girl had been unconscious since Dec. 10 when the 2008 Honda Accord she was driving west on Floating Feather was struck by a 2010 Jeep Grand Cherokee headed north on the highway about 6:45 p.m., according to the Ada County Sheriff's Office.

A 16-year-old boy in the Accord was seriously injured but is recovering. The Jeep's driver, a 50-year-old Emmett woman, also was injured and is receiving ongoing medical care.

Investigators say the girl stopped at a stop sign on Floating Feather Road at the highway. She waited a few seconds before proceeding but when she did was immediately broadsided by the Jeep.

All three were wearing seat belts and both vehicle had working airbags.

The investigation is ongoing and will be forwarded to the Ada County Prosecutor's Office for review.

The girl was pronounced dead Tuesday evening at Saint Alphonsus Regional Medical Center. Her name has not yet been released.
