MOORHEAD (AP) - Law enforcement officials in the Moorhead and Fargo, North Dakota, metropolitan area are pledging public safety and security while investigators look for clues in the killing of a North Dakota State University student earlier this week.

The body of 18-year-old Thomas Bearson, of Sartell, Minnesota, was found Tuesday outside a recreational vehicle store in Moorhead. The Ramsey County medical examiner's office said Bearson died as the "result of homicidal violence."

Authorities have released few details. Moorhead Police Lt. Tory Jacobson says there are "more questions than answers" and investigators from at least five agencies are working to "ultimately get on the trail" of a suspect or suspects.

Fargo Police Lt. Joel Vettel says people should have a "heightened level of concern" but should not be alarmed or live in fear.
