Authorities found Matthew's truck within three miles of his last known location. The 2007 Dodge Dakota, Utah license plate A983HZ, contained important personal belongings, including his dentures, according to Missing Persons Alerts.

There are very strong concerns for Mr. Dustin's safety, seeing as so much time has passed and his truck was located weeks ago. Authorities ask anyone traveling through the St. Charles area to watch for anything out of the ordinary.
