According to police it was just after 7:30 a.m. when officers arrived on scene and found two passenger cars and an SUV all damaged.

One man was trapped under the SUV and was pronounced dead at the scene. A pregnant woman, who was the driver of one of the cars, was taken to a local hospital with life-threatening injuries. Doctors were able to deliver her child, but unfortunately, both the woman and the newborn died from their injuries.

Investigators believe before the crash, one of the cars was experienced some kind of mechanical issue, causing the driver to pull over. The second car stopped directly behind it. It’s believed the driver of that driver was trying to help the first vehicle.
