Abigail Yearber: Two Official Profiles and the Hermosa Beach Record
A comparison of the April 2012 contact description, matching case identifiers, and differently labelled record dates.
Abstract
Abigail Yearber’s California Department of Justice and NamUs profiles identify April 7, 2012 and Hermosa Beach as the last-seen date and locality. Neither reviewed narrative supplies a detailed account of the observation. This paper compares the two profiles, retaining their shared agency case number and differing telephone references without mistaking database publication for a later sighting.
The Shared Case Anchors
NamUs MP90176 identifies Yearber as 17 at disappearance and places last contact in Hermosa Beach, California, on April 7, 2012. The California DOJ profile gives the same date under Missing Since and states that she was last seen in Hermosa Beach. Both identify Hermosa Beach Police Department and case 121044.1,2
The agreement helps match the two profiles to the same case. It does not make them independent witnesses. Neither public narrative identifies the observer, time of day, exact site, companion, or destination.
The Dates of the Record
NamUs gives March 31, 2022 under NamUs Case Created. Its surrounding webpage displays May 7, 2026 under Date Created, while the agency Date Reported field is blank.1 Those dates describe records with different labels, not additional observations of Yearber. The blank reporting field cannot establish when police first received information.
Matching the Agency References
The California DOJ profile lists telephone (310) 318-0360; NamUs displays (310) 524-2750. Both attach their contact information to Hermosa Beach Police Department and case 121044.1,2 This paper retains the source distinction rather than silently treating the numbers as interchangeable or declaring one erroneous. An agency confirmation would be needed to establish the appropriate current contact.
Sourced Accounts and Questions
The reviewed profiles agree on the last-seen day and locality but provide no detailed observation narrative.1,2 The differing contact numbers concern source metadata; they are not competing accounts of what happened to Yearber.
Can you find a public agency account explaining the observation behind April 7? An attributable statement giving its time and location context could make the chronology more precise. The common date alone cannot establish a departure sequence.
When you compare a later notice, can you distinguish a newly documented contact from repetition of these profiles? Match MP90176 and case 121044, retaining the source date and the event date separately.
Here’s where you come in: explore these open questions in your own Research File in Almost Solved. Keep both source references beside your notes and seek attributable clarification rather than filling the missing sequence with assumptions. Relevant information belongs with investigators.
Conclusion
The two official profiles provide a consistent case identity and a last-seen anchor. They do not explain the disappearance or establish subsequent movements. Preserving their dates and contact differences makes later checking possible without overstating what their agreement proves.
Scope and Method
Public source records were individually reviewed in the ordinary browser on November 1, 2026. This focused study does not claim new interviews, access to a complete investigation, or confirmation of present whereabouts. NamUs displayed a processing and case-update delay notice. The review date does not establish when every underlying field was last updated.
