Federal investigators say they are investigating the crash of a helicopter in southeast Alabama that reportedly killed three crew members and the patient they were transporting.

Troy Regional Medical Center CEO Teresa Grimes says in a Facebook post Saturday that the medical center "is saddened" by the loss of the crew and patient during the transport Friday evening.

Coffee County EMA Deputy Director James Brown tells WSFA-TV that four people were aboard the helicopter. He says the helicopter went missing around 12:17 a.m. Saturday. The downed helicopter was found just after 7 a.m.

The National Transportation Safety Board said on Twitter that it was investigating a helicopter crash in Goodman, Alabama. News reports say a Federal Aviation Administration team from Birmingham is on the way to the scene.
