HUMBOLDT Shannon Henderson, 37, Humboldt, was injured Saturday in a one-vehicle crash east of Humboldt Saturday morning.
The Allen County Sheriffs Department reported Henderson had apparently fallen asleep while driving home from working an overnight shift in Chanute.
Three witnesses told deputies they saw Hendersons vehicle, a 2016 Dodge Grand Caravan, drift across the road as it traveled on Delaware Road, about 1½ miles from the old Zillah School building, or about 5½ miles east of Humboldt.
The van traveled about 220 feet in the ditch before squarely striking an embankment with a metal culvert, which caused all of the vehicles airbags to deploy.
Henderson, who was wearing her seat belt, was trapped inside the van.
Iola firefighters extricated Henderson from the vehicle. Meanwhile, Humboldt firefighters and Kansas Highway Patrol troopers assisted in blocking off traffic for a landing zone for an air ambulance that flew Henderson to Overland Park Regional Medical Center.
