Seven year old boy found dead in Kotzebue.

Authorities in the state's Northwest Arctic Borough are investigating the death of a seven year old boy found dead Sunday in Kotzebue about a

day after he had gone missing.

Sources close to News Center 11 say Suuyuk ("soo-yook") Brown died of exposure after searchers found him in a remote area.

They say the young boy may have fallen into a crevasse and become stuck.

Brown had left home on Saturday, and family members became concerned after he didn't come home that evening.

Brown was a first grade student at Kotzebue-based June Nelson Elementary School.

Sources say his body was located Sunday evening in an industrial area where barge and other shipping equipment are kept.
