WAHOO, Neb. (KCAU) – UPDATE: The Nebraska State Patrol (NSP) identified a third vehicle that was at the intersection of Highway 77 and Highway 109 at the time of the crash that killed three siblings Tuesday evening.

According to the NSP, after requesting assistance from the public in locating the driver of a third vehicle, several citizens called with information, including the driver of the third vehicle.

Following interviews, including those with other witnesses, investigators believe the third vehicle had not stopped at the intersection, but had slowed down after noticing the southbound vehicle proceed into the intersection after stopping at the stop sign on Highway 109. The third vehicle was able to stop in time to avoid a collision, but an eastbound vehicle, traveling in the right lane, collided with the southbound vehicle.

All three occupants of the southbound vehicle, 18, 11, and 7-year-old siblings from Wahoo, were killed in the crash.

The driver of the third vehicle then noticed several witnesses stop to assist and made sure 911 had been called before departing the scene and is not believed to be a contributing factor in the crash.

The investigation remains ongoing.
