BOISE - Idaho State Police are investigating a rollover crash on Interstate 84 Sunday night that killed one woman and sent two people to the hospital, one of those a toddler.
The crash happened just before 5 p.m. between Mountain Home and Boise.
Police say the driver of the car, Sandra Sanders, 48, of Stockton, Utah, drifted off the eastbound lanes of I-84 and into the median.
The Ford Taurus then hit a drain in the median and troopers say that launched the vehicle 70 feet in the air.
A passenger, 67-year-old Mildred Corey, died at the scene. She is also from Stockton, Utah.
Sanders and a 2-year-old girl were taken to St. Alphonsus Regional Medical Center in Boise. Both have non-life-threatening injuries.
"The two patients were conscious, but they both had pretty significant injuries," said Clinton Wolf of the Ada County Paramedics.
Troopers say it appears all three people inside the car were wearing seatbelts.
After talking with witnesses, troopers think the driver may have fallen asleep.
"There were no indications of erratic driving patterns that would lead us to believe it was anything other than a distraction or a drowsy driver," said Sgt. John Stauffer.
