KSFY has learned more about a crash scene along interstate 90 that killed four members of a Sioux Falls family.
The driver, James Vollmer, 52, and his wife Julie, 48, were driving with two of their three children, Alyssa, 16, and Caleb, 13.
We have obtained photos of the family but are awaiting appropriate confirmation before we share them with you.
The accident happened just before 5:15 last night here along interstate 90 near mile marker 395, that's just a few miles west of interstate 29.
This is video from the scene, South Dakota highway patrols says the family was traveling west-bound along I-90 when the car veered off the road, entered the median, striking a guardrail and then an embankment before it came to rest.
The driver and two children died at the scene, Julie was airlifted but later died from her injuries.
The Vollmer family leaves behind their oldest daughter, Brittany, a student away at Northwestern College.
We learned the family was active in the Sioux Falls Christian Schools community, and today members of that community joined to grieve.
A lot of people have said this is just unimaginable.
We spoke with several people today who knew the Vollmer family.
They say it's surreal, they can't believe it, and they're in shock.
Classmates of 13-year-old Caleb and 16-year-old Alyssa Vollmer gathered today to pay tribute to the friends they lost.
Sioux Falls Christian School opened up its doors this afternoon for middle school and high school students and their parents.
It was a chance for people to come together, spending time remembering Caleb and Alyssa.
Superintendent Jay Woudstra tells us it was a good opportunity to reflect, to mourn and to grieve.
"Tragedy is difficult, anytime. facing death is difficult, anytime. And when you lose two students, a seventh grader and a sophomore, those are difficult times, but you always have the assurance of the cross and the resurrection of Jesus Christ that you fall back on. In those tough times, there's a lot of 'why' questions but in the end, that's where our hope is," Woudstra said.
