WAHOO, Neb. -- Authorities say multiple people have died in a crash in eastern Nebraska.

It happened Tuesday afternoon near the intersection of Highways 77 and 109 just north of Wahoo.

Authorities say a car driven by 18-year-old Monica Chohon was hit as it was driving through the intersection and rolled into a nearby ditch.

Monica Chohon, 11-year-old James Chohon and 7-year-old Andrew Chohon, all from Wahoo, were pronounced dead at the scene.

The Nebraska State Patrol was able to identify a third vehicle that was at the intersection of Highway 77 and Highway 109 at the time of the crash.

After NSP requested assistance from the public in locating the driver of a third vehicle, several citizens called with information, including the driver of the third vehicle, which was a Ford Escape.

Following interviews, including those with other witnesses, investigators believe the eastbound Escape had not stopped at the intersection, but had slowed down after noticing a southbound Pontiac Grand Am proceed into the intersection after stopping at the stop sign on Highway 109. The Escape was able to stop in time to avoid a collision, but an eastbound Dodge Ram 3500, traveling in the right lane, collided with the Grand Am, the vehicle with all three victims. 

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

The investigation is ongoing.

The Nebraska State Patrol is asking anyone who witnessed the accident to contact authorities.
