(KNZA)--A Valley Falls woman has died from injuries received in a single-vehicle wreck over the weekend in Shawnee County.

According to an obituary from the Mercer Funeral Home in Valley Falls, 77-year-old Margaret Heuertz died Monday at a Topeka hospital.

The Shawnee County Sheriff’s Department says Heuertz was westbound on Northeast Calhoun Bluff Road early Saturday evening when her Dodge Durango drifted off the north side of the road, causing Heuertz to lose control.  The vehicle crossed both lanes of traffic and struck a guardrail, causing the vehicle to roll into a creek.

A deputy located her vehicle underneath a bridge.

The Sheriff’s Department says Heuertz was able to self extricate herself.  She was transported to a local hospital.

The Sheriff's Department was investigating if a medical issue led to the wreck.

Mass of Christian Burial for Heuertz will be held Saturday morning at 10:30 at St. Aloysius Catholic Church in Meriden.
