MOORHEAD, Minn. (AP) — A coroner in Minnesota has ruled as a homicide the death of the North Dakota State University student whose body was found this week.

The Ramsey County medical examiner's office on Thursday determined that 18-year-old Thomas Bearson, of Sartell, Minnesota, died as the "result of homicidal violence."

Bearson's remains were found Tuesday outside a recreational vehicle store in south Moorhead. He was last seen at a party Saturday in Fargo.

Police in Moorhead are asking for the public's help to locate Bearson's cellphone and a shoe. Police described the missing items as a white Nike Air Jordan left tennis shoe size 9½ and a silver iPhone 5.
