Alaska State Troopers have closed their investigation into a death in Akutan, and say no foul play is suspected.

Simon Gatpan, 31, of Santa Clara, California, was found dead on a beach in the Aleutian community last weekend. Trooper spokesperson Megan Peters says an autopsy showed that he died of exposure. She adds that alcohol is believed to be a factor. Gatpan was last seen walking home from a local bar and was found unresponsive on the beach in the morning.
