Authorities say a medical helicopter has crashed in Oklahoma City, killing two people and injuring a third.

The Oklahoma City Fire Department tells The Oklahoman newspaper ( http://is.gd/9QfVj2) that the crash happened Friday morning. A fire department spokesman says two people were killed and one person was taken to a hospital.

Authorities say the crash happened near the St. Ann Nursing Home in northwest Oklahoma City.

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.
