CANYON COUNTY -- Two sisters from Middleton are dead after a manure truck and a passenger car collided at the intersection of Old Highway 30 and Farmway Road around 4:30 p.m. Thursday.
Authorities say three siblings were inside the car when the accident happened.
Idaho State Police say the white passenger car was headed south on Farmway Road when it came to the intersection. Troopers don't know if the car stopped at the stop sign, then pulled forward, or ran the stop sign. The car turned left at the intersection when a manure truck, headed west on Old Highway 30, hit the car. Police estimate the truck was going around 50-55 mph.
Sergeant Jason Cagle with the Idaho State Police says a group of people living in a house nearby heard the deadly crash.
"There was a lot of people that live in the house that's right across the street," Cagle said. "Some of them heard the crash, called friends, some of them came out and they were present, but they didn't necessarily witness the crash."
Police said the 17-year-old driver, Ashton Braden, and her 6-year-old sister, Sophie Moore, died at the scene. A third sister, 11-year-old Zoey Moore, was taken via air ambulance to Saint Alphonsus Regional Medical Center in Boise. Her condition has not been released.
"The fire department had to extricate the bodies out of the car. It was a pretty serious crash," said Sgt. Cagle.
Police say the driver of the manure truck, Alberto Luna, was not hurt and wasn't ticketed or cited. However, the cause of the crash remains under investigation.
In addition to state police, Canyon County sheriff's deputies, paramedics and Middleton firefighters responded to the crash.
Crews cleared the scene and reopened the roads around 8 p.m. Thursday.
