INMAN, Neb. (AP) — A 56-year-old O’Neill woman has died after crashing off U.S. Highway 20/275 in northern Nebraska.

The accident occurred west of Inman on Saturday. The Holt County Sheriff’s Office says Debra Christensen’s westbound vehicle crossed the center line and eventually slid sideways into a roadside ditch and rolled, landing on its top.

Christensen, who was ejected, was taken to an O’Neill hospital and then flown to Mercy Medical Center in Sioux City, Iowa. Mercy Medical Center spokeswoman Dianne Krier (kreer) said Tuesday that Christensen died around 5 p.m. Sunday.
