OKLAHOMA CITY (AP) — Authorities say a medical helicopter has crashed in Oklahoma City, killing two people and injuring a third.

Authorities told The Oklahoman newspaper (http://is.gd/9QfVj2 ) that the crash happened Friday morning near the St. Ann Nursing Home in northwest Oklahoma City.

Emergency Medical Services Authority spokeswoman Lara O'Leary says no one on the ground was seriously hurt or killed and that the person taken to OU Medical Center was believed to be on the helicopter with those killed.

She says the helicopter belonged to Kansas-based company EagleMed.

A large storm system has blanketed much of the Midwest and Plains in snow, but it wasn't immediately clear if authorities believe weather played a role in the crash.
