Authorities say wintry weather has killed four more people on Kansas roads including one person from Winnipeg.

Harvey County Sheriff T. Walton blamed icy roads for a double fatality crash around 3 p.m. Friday about 10 miles southeast of Newton.

Two others died a couple hours later when a truck jackknifed on an icy stretch of Interstate 35 near Andover, went through a median barrier and struck a sport utility vehicle. The crash killed the SUV's driver, 65-year-old Shirley Ann Starr, of Kansas City, Missouri, and a truck passenger, 60-year-old Arlene Dale Harrison, of Winnipeg, in the Canadian province of Manitoba.

The Kansas Highway Patrol also blamed icy roads for two deadly crashes Thursday. Much of Kansas was hit with snow and freezing rain that began Thursday and continued to roll across the state Friday.
