Three people are dead after an overnight Bismarck Air Medical Plane Crash.
Law enforcement officers say the flight was leaving from Bismarck to Williston after 10 last night. Deputies say they had no response from the flight at around 11.
The three people on the flight were first responders on their way to pick a patient up for transport.
Inside the plane during the deadly crash was an AirMed pilot, a paramedic and a CHI St. Alexius nurse.
Sheriff Kyle Kirchmeier says he has never seen a plane crash with this kind of debris field before
The Morton County Sheriff's Department says they last heard from the people on the plane around 11 p.m.
Deputies didn't find the site of the crash northwest of Mandan until after 1 a.m.
Sheriff Kyle Kirchmeier says with the help of civil air patrol and an air force rescue team in Florida, they were able to find where the plane went.
Kirchmeier: "What they did is that they have the ability to be able to analyze the radar tracks and to be able to further pinpoint these locations of these type of incidents. We also used the cellphone forensics to ping cellphones."
Many responders across the state are giving extending their condolences for the first responders lost.
Kirchmeier: "It affects all of us in one way or the other. We keep pressing on and do what we do to help where we can.
The national Transport Safety Board and the Federal Aviation Administration are investigating this incident.
How the plane crash happened is still unknown.
Kirchmeier says this is going to take a little more time than usual to figure out the cause of the crash because of the large debris field.
