LAST-KNOWN CONTEXT (UP TO DATE OF DISAPPEARANCE)

◆ Residence

Subject's last verified address (per public records) was a rented unit on G Street in Petaluma, occupied 2008-04 through 2010-11. The property was rented; subject was not the deed holder. [EV-00080]

◆ Vehicle (last documented)

A 2003 Subaru Outback, dark green, partial plate redacted, was registered to subject through 2010. The vehicle's subsequent status (transferred, abandoned, reported recovered) is not visible in public records and is recommended for agency follow-up via DMV records request. [EV-00086]

◆ Employment

Subject's last documented employment, per a 2010 newspaper feature in the Petaluma River Press, was at the same publication as a copy editor. The masthead from October 2010 lists subject; the November 2010 issue does not. [EV-00081]

◆ Public-record associates

Public records indicate subject co-owned a small bookselling cooperative with one individual (named in public business filings) from 2003 to 2006. The business was dissolved per California Secretary of State filings on 2006-09-15. This co-owner is named in public records and is not identified by Sequenxa as a person of interest — agency follow-up at the agency's discretion. [EV-00082]

RECOMMENDED AGENCY ACTION TEMPLATE

Sequenxa recommends the following sequence of agency actions following identification:

  1. 01

    Next-of-kin notification

    • Maternal aunt has consented to identification process; recommend formal notification visit within 72 hours.
    • Coordinate with Marin Co. Victim Advocate Services.
    • Notification SHOULD precede any public release.
  2. 02

    NamUs record update

    • UP record UP-104112 status update to IDENTIFIED.
    • Cross-link to Othram case OTH-2024-1102.
  3. 03

    Investigative follow-up

    • DMV records request for final vehicle disposition (§ 3).
    • Historical employment-records request to former employer (§ 3).
    • Co-owner of business interview (§ 3) — note this individual is not classified as a suspect but may have last-contact knowledge.
  4. 04

    Public release (after NOK notification)

    • Sequenxa can produce a public-release-ready summary on request.
  5. 05

    DNASolves attribution (Othram coordination)

    • If DNASolves contributors aided identification, Othram will coordinate any acknowledgment. Sequenxa is not the appropriate channel for genetic-contribution acknowledgment.
  6. 06

    Case closure pathway

    • If no homicide investigation continues from this identification, coordinate with ME for death-certificate amendment and case closure.
◇ § 7
