(KNZA)--Heavy fog may have played a role in a two-vehicle Nemaha County crash Thursday morning that claimed the life of a Wetmore woman and left four others injured, including three children.

The Kansas Highway Patrol says the wreck happened shortly before 8:30 at the intersection of U.S. 36 Highway and W Road about 4 miles south of Sabetha.

The Patrol says 37-year-old Rebecca Lynne Crismas was southbound on W Road when she failed to yield at a stop sign and her van was struck by a westbound semi on U.S. 36.  

Crismas was pronounced dead at the scene.

Three children in her van, ranging in age from 1 to 11, were injured.  One-year-old Jedediah Crismas and 11-year-old Juliana Crismas were both taken to Children's Mercy Hospital in Kansas City.  3-year-old Joshua Crismas was transported to the Sabetha Community Hospital.

The semi driver, 63-year-old Lacygne, Kansas resident Wayne Mowery, was transported to Topeka’s Stormont-Vail Regional Health Center.

The Patrol says all those involved were properly restrained. 

The wreck closed down a portion of U.S. 36 Highway in Nemaha County for around six hours.
