Andrea Mona Altiery Disappearance: What Happened in the 1981 Alaska Missing Person Case?

Andrea Mona Altiery vanished without a trace on the night of December 2, 1981, in Anchorage, Alaska. More than four decades later, investigators strongly believe she became one of the unidentified victims of notorious Alaska serial killer Robert Hansen, yet her disappearance remains officially unresolved because her remains have never been found.

Altiery was 24 years old when she disappeared. She worked as an exotic dancer in Anchorage using the stage name “Enchantment” and was affectionately known by friends as “Fish.” According to investigators, she left for what was described as a photography appointment with an unidentified man after taking a taxi to Boniface Mall around 11:00 p.m. She never returned home and has never been seen again.

Evidence Linking Andrea Altiery to Robert Hansen

The investigation took a significant turn after authorities arrested serial killer Robert Hansen in 1983.

During the execution of a search warrant at Hansen’s residence, investigators recovered several items identified as belonging to Andrea Altiery. Among the most notable was her distinctive custom-made salmon-shaped necklace featuring a diamond eye, an item that friends and investigators considered highly unique. Other jewelry associated with Altiery was also reportedly recovered from Hansen’s home.

Hansen eventually confessed to murdering numerous women throughout Alaska, leading investigators to several burial sites. However, he admitted to fewer killings than investigators suspected, and several women believed to be his victims—including Andrea Altiery—were never recovered.

Authorities have long believed Hansen’s map, which contained more marked locations than the number of murders he admitted committing, indicates there may still be undiscovered victims. Andrea’s disappearance continues to be considered one of those unresolved cases.

Investigation Status

Andrea Altiery remains classified as an endangered missing person.

Despite the strong circumstantial evidence connecting her disappearance to Robert Hansen, investigators have never recovered her remains, preventing a complete resolution of the case. Hansen died in prison in 2014 while serving multiple life sentences, taking with him the location of many suspected victims whose remains have never been located.

Andrea’s case remains active in national missing persons databases. Investigators continue to encourage anyone with information regarding her disappearance or the possible location of her remains to contact law enforcement.

Latest Investigation Information

There have been no publicly announced major investigative breakthroughs or recoveries in Andrea Altiery’s case in recent years. She remains listed as an active missing person in NamUs, and Alaska authorities continue to accept information related to her disappearance. Public databases continue to identify Robert Hansen as the primary suspect, but because Andrea’s body has never been found, the case has not been officially closed.
