A Warren woman has been killed in a crash in Portage County Monday morning.

According to a press release from OSP's Ravenna post, 49-year-old Sonia Grimmett of Warren was killed after her 2004 Chevy 3500 van gradually traveled left of center and eventually off the roadway on Route 305 east of Nelson Parkman Road in Nelson Township.

Once the vehicle was off the road, it struck a utility pole.

Grimmett was taken to an area hospital in critical condition, where she later succumbed to her injuries. Troopers say she was not wearing a seatbelt at the time of the crash.

The crash is currently under investigation.
