WICHITA, Kan. (KAKE) - Two Kansas residents were killed in separate rollover crashes in the western part of the state on Christmas Eve, according to the state patrol.

The first accident happened at around 6:15 p.m. on K-156 east of U.S. 83 in Finney County. The Kansas Highway Patrol reports 23-year-old Melina Chavez was heading west when her Ford Edge left the roadway to the right, went back across the road and went off the left side. The SUV spun as it entered a ditch and then rolled an unknown number of times. 

Chavez, of Great Bend, was taken to a Garden City hospital where she died. The KHP crash log states she was not wearing a seat belt at the time of the accident. It's unclear what initially caused her vehicle to go off the roadway.

Saturday's second fatal crash occurred at around 9 p.m. at North Road and 255th Avenue southwest of Hill City in Graham County. The patrol says 40-year-old Ali Swanson was eastbound on North Road and failed to negotiate a curve in the road. His Cadillac DeVille went of the road and rolled onto its top. 

Swanson, of Salina, died at the scene. That crash log states he wasn't wearing a seat belt.
