Peterson, IA — July 14, 2025, Coree Keller was killed, and Nichoas Seaburg and three children were injured in a truck accident at around 10:00 a.m. on M-27.
According to authorities, the accident took place on M-27 in the vicinity several miles south of Peterson.
Officials indicate that, for as yet unknown reasons, a Subaru Outback—occupied by 42-year-old Coree Keller, 37-year-old Nicholas Seaburg, and three children ages 5, 7, and 11—that had been traveling on M-27 attempted a left turn at an apparently unsafe time, failing to yield the right-of-way to an oncoming 18-wheeler. A collision consequently took place between the Outback and the truck.
Keller reportedly sustained fatal injuries over the course of the accident and was declared deceased at the scene. The 11-year-old and the five-year-old suffered severe injuries and were flown to area medical facilities in order to receive immediate treatment. The 7-year-old was also injured and was transported to a local medical facility by EMS for care. Reports also state that Seaburg was hurt, as well, though the severity of his injuries is unclear.
Additional details pertaining to this incident are not available at this point in time. The investigation is currently ongoing.

When a vehicle carrying a family attempts a turn in front of an oncoming 18-wheeler, the tragic result isn’t just a matter of timing—it’s a question of what information the driver had available to make that decision, and whether the truck driver had any chance to prevent the collision. The investigation now must focus on those split seconds leading up to the crash, and whether this devastating outcome could have been avoided.
If the Subaru attempted a left turn across the truck’s path, that typically indicates a failure to yield. But determining why that turn was made—especially on a rural highway like M-27—requires examining more than just fault on paper. Was the view of oncoming traffic obstructed by a curve, hill, vegetation, or another vehicle? Was there confusion about the truck’s speed or distance? Did the driver mistakenly believe they had enough time to clear the roadway?
At the same time, the truck’s speed and positioning are central to understanding whether the crash was truly unavoidable. In past cases I’ve handled, we’ve seen trucks traveling just a few miles per hour over the limit shorten available reaction time enough to make a survivable decision deadly. Investigators should review black box data to confirm how fast the truck was going, whether brakes were applied, and how the driver responded once the turning vehicle entered the roadway.
The fact that children were in the vehicle also raises important concerns about crash dynamics and restraint systems. Investigators will likely evaluate seating positions and injury patterns to assess whether all safety measures were in place—information that may not affect liability but will be relevant in understanding the full scope of harm.
Ultimately, responsibility comes down to more than who turned and who had the right of way. It comes down to whether either driver had a real opportunity to avoid impact—and whether one or both misread a situation that gave them little time to correct.
Key Takeaways
- The key issue is whether the driver of the Subaru misjudged the distance or speed of the oncoming truck, and why that miscalculation occurred.
- Investigators should examine visibility at the scene, including road layout, sight obstructions, and traffic conditions.
- Black box data from the 18-wheeler will be essential to determine speed, braking response, and whether the driver attempted to avoid the crash.
- The presence of multiple child passengers highlights the need to evaluate crash severity, seating arrangements, and restraint use.
- Determining accountability requires understanding not just right-of-way, but what each driver knew—and could reasonably react to—in the seconds before impact.
