A medical transport helicopter crashed Monday in Mississippi, while carrying two hospital workers and a pilot, officials said.

A pilot and two crew members were aboard the helicopter, which was not carrying any patients when it plunged into the woods outside Jackson, Miss.

The helicopter was returning to Columbus from a patient transport when it crashed in Madison County at around 12:30 pm, killing everyone on board, the University of Mississippi Medical Center’s vice chancellor for health affairs, Dr. LouAnn Woodward, said at a press conference.
