Detailed Case Breakdown

Sonia Iris Agosto Salgado: Anchorage Woman Missing Since December 2015

Sonia Iris Agosto Salgado was 50 years old when she disappeared from Anchorage, Alaska, on December 16, 2015. More than a decade later, publicly available records continue to list her as missing, while remarkably little information has been released about what happened before or after her disappearance.

Sonia Iris Agosto Salgado Disappears in Anchorage

The documented circumstances surrounding Sonia’s disappearance are extremely limited. Her recorded date of last contact is December 16, 2015, and her last known location is Anchorage, Alaska, in Anchorage Borough. Publicly available case information simply states that Sonia was last seen on that date.

The Anchorage Police Department is identified as the investigating agency, and the law-enforcement case number associated with her disappearance is 150050969. Sonia’s case was subsequently entered into the National Missing and Unidentified Persons System as NamUs MP67030.

What Sonia Was Wearing When She Disappeared

Available case information describes Sonia as approximately 5 feet tall and 200 pounds, with black hair and brown eyes. She is listed as White/Caucasian in the available records.

Her reported clothing provides one of the few potentially significant details available to the public. Sonia was reportedly wearing a black Fat Ptarmigan uniform, black T-shirt and blue jeans around the time she disappeared.

The reference to a work-style uniform may potentially help someone remember seeing her, but publicly available records reviewed for this article do not explain where Sonia was working, where she was traveling, who last saw her, or precisely where in Anchorage she was last observed.

Few Details Have Been Released About the Circumstances

One of the most striking aspects of Sonia’s case is how little information has become publicly available.

There are no publicly documented circumstances in the sources reviewed identifying a vehicle connected with her disappearance, a specific Anchorage address where she was last seen, a publicly identified last-known witness, or a publicly announced suspect. There is likewise no verified public information in the reviewed sources establishing that Sonia was the victim of a homicide.

Because of those gaps, conclusions about what happened to Sonia would be speculation. She should continue to be described as a missing person unless law enforcement releases information changing the status of her case.

The Case Entered NamUs Years After Sonia Disappeared

Although Sonia disappeared in December 2015, the available NamUs information reproduced in current case resources states that her NamUs case was created on March 17, 2020, more than four years after her last known contact.

Her NamUs identification is MP67030. Other missing-person databases and awareness projects have since created pages or flyers for Sonia, helping keep her name and photograph accessible to the public.

Renewed Online Attention Years Later

Public awareness of Sonia’s disappearance has continued long after 2015.

Crime Solvers Central published an article about the unresolved disappearance on April 29, 2025, highlighting how few details about the case have been publicly disclosed.

A Websleuths discussion specifically dedicated to Sonia’s disappearance was started on January 18, 2026. The discussion reproduced case information including her physical description, last-contact date, Anchorage location and reported clothing.

CaseTrace also maintains a missing-person flyer identifying Sonia as missing from Anchorage since December 16, 2015, with NamUs case 67030 as its official source reference.

Latest Information on the Investigation

As of the latest publicly accessible information reviewed in August 2026, there is no verified announcement that Sonia has been located and no publicly documented resolution of her disappearance.

Current online case resources continue to describe Sonia as missing. CrimeTea identifies the case as active, while recent missing-person and cold-case resources continue to include her among Anchorage missing persons.

No credible public source located during this review announced an arrest, suspect, recovery of remains, confirmed sighting, or determination that Sonia died. The absence of a public announcement does not establish that investigators have no additional information; investigative agencies frequently withhold information that could affect an open case.

Anchorage Police Department currently directs people with information about missing-person cases to contact its dispatch system at 311 or 907-786-8900. APD’s Detective Division also maintains responsibility for homicide, missing-person and cold-case investigations.

Why Sonia’s Case Still Needs Attention

More than ten years have passed since Sonia Iris Agosto Salgado was last known to be in Anchorage.

What happened on December 16, 2015 remains unanswered in the publicly available record. Even a seemingly minor recollection—where Sonia was seen, who she was with, transportation she may have used, or something said shortly before she disappeared—could potentially provide information investigators did not previously have.

Anyone with firsthand information should provide it directly to law enforcement rather than attempting to investigate or confront anyone independently.
