LINCOLN, Neb. -- The Lancaster County Sheriff's Office is investigating a two-vehicle collision at the intersection of SW 14th Street and Highway 33 that sent multiple people to the hospital.

Investigators say that a southbound 2012 Chrysler 200 failed to stop at a stop sign Saturday night just before midnight. Authorities say the car was then struck by a 2015 Chevrolet Silverado that was eastbound on Highway 33.

The Chrysler 200 held four people, including the driver. All four were taken to the Bryan Medical Center West Campus, including two in critical condition. The other two are in stable condition. The driver and passenger in the Silverado were treated and released with minor injuries.

Preliminary evidence indicates that seatbelts were in use by the occupants of the 2015 Chevrolet Silverado. Seatbelt use by the occupants of the 2012 Chrysler is unknown at this time.
