A moose hunter found a badly decomposed body on a bank of the upper Susitna River northwest of Glennallen, according to the Alaska State Troopers.
The discovery was reported Wednesday night, the troopers said in a written statement, and "we think we know who it is," said spokeswoman Megan Peters.
Troopers are waiting for the state's medical examiner to confirm the identity of the body, most likely using dental or X-ray records, before releasing further details, Peters said.
The body was discovered near the Susitna's confluence with Tyone Creek by a moose hunter who had flown into the area, the troopers' statement said, and it was retrieved by a helicopter on Thursday.
