The girls were riding in a small passenger vehicle when it collided with a semitruck at an intersection in the city of Tishomingo, about 122 miles south of Oklahoma City.
There is a stop sign regulating traffic at this intersection and the posted speed limit for the highway is 50 mph. Witnesses said the Chevy entered US-377 after making a “rolling stop” at the stop sign and was hit by the semitruck on the front-left, which pushed it off the roadway, according to the update.
The semitruck then veered off the road and came to stop in a private driveway off the highway. The driver of the truck was uninjured, the statement said.
The investigation is continuing and the NTSB, in coordination with the Oklahoma Highway Patrol, has sent a team of four investigators and a family assistance specialist to Oklahoma to look into several issues.
They will be evaluating highway conditions, like lighting and weather conditions, as well as accident histories at the site and potential reasons behind human error. They will also examine the vehicle’s compliance with federal and state regulations.
Investigators will reconstruct the crash events and analyze physical evidence and vehicle damage, the statement said.
The team’s on-scene work is expected to conclude by Monday and a preliminary report is expected late next month. The full investigation — which would include probable cause and any contributing factors — will be completed in the next year or two.
”On behalf of our students, staff, families, and community I want to thank you for your thoughtfulness, prayers and encouragement,” said Bobby Waitman, Tishomingo Public Schools superintendent, in a statement.
“As we begin the process of broken hearts, I am reminded that our greatest priority as educators is to meet the emotional, mental, social and physical needs of our students. This is our focus at this time – and every day that we serve our students,” Waitman’s statement added.
