The safe contained $100,000 but was found in the back yard of the victim's home with just $20,000 missing. The theft occurred Friday.
Troopers spokeswoman Megan Peters tells the Fairbanks Daily News-Miner that the safe measured only about a cubic foot and was relatively lightweight.
She says there were no signs that anyone had broken into the house.
Troopers have identified a suspect.
They have not specified the neighborhood where the safe was taken. Peters says they don't want to tell potential thieves where there's a safe with $80,000 in it.
