Details of Disappearance Matthew was last seen at his residence in Idaho Falls, Idaho on January 22, 2018. He left between 2:00 and 7:00 a.m., driving a gray 2009 Nissan Versa hatchback with the Idaho license plate number 8B EF732, taking camping and survival gear and a 9mm handgun. He left a note behind, indicating he planned to take his own life.
A photo of a 2009 Nissan Versa is posted with this case summary; it has not been located. The driver's side rear hubcap on the car is missing. Matthew did leave a journal lying in the snow near where the Versa had previously been parked; it had a detailed list of items he planned to take with him, as well as several disguise plans. He enjoyed the reality TV show "Hunted", where teams of two people would attempt to avoid being found by investigators for four weeks.
Authorities do not know whether Matthew followed through on his plan to die by suicide, or if he is still alive; the bodies of people who take their own lives are usually found quickly. Matthew's father stated he was a straight-A student and an experienced camper. He was a member of the Civil Air Patrol and planned to join the military after high school. His case remains unsolved.
