(KAIR)--One person is dead, and two others injured, following a single-vehicle crash in Leavenworth.

Leavenworth Police Chief Pat Kitchens, in a release Monday, said the police department “worked a fatality accident overnight at Tonganoxie Road near the entrance to Shenandoah.”

According to the release, a Leavenworth County Sheriff’s Deputy “discovered what appeared to be damage to a speed sign and debris in the roadway.” Stopping to investigate, the deputy discovered the fatal crash.

According to Kitchens, the involved vehicle “was traveling south on Tonganoxie Road, lost control, left the roadway and went down an embankment.”

A 23-year-old occupant of the vehicle died at the scene, while a 22-year-old woman was flown by Life Flight Helicopter to a Kansas City hospital in critical condition. A 24-year-old man was taken by ground ambulance to a Kansas City hospital, also in critical condition.

Names were not immediately made public, but Kitchens said all three are residents of Leavenworth County.

According to Kitchens, the Leavenworth Police Department’s traffic unit is handling the investigation.

Multiple fire departments, as well as Lansing Police, and the Leavenworth County Sheriff’s Office all assisted.
