Timeline
- 26 Jun 2025, 6:13 am: surveillance shows her driving husband Mark to LANL; she leaves at 6:20, alone, and never takes her usual route to her own job.
- Later that day she unexpectedly returned home and took a sandwich to her daughter's workplace. Last seen walking alone on a rural highway near Ranchos de Taos.
- She left her purse, ID, keys and wallet at home. Both phones were wiped and factory-reset.
- 28 May 2026: a hiker finds her remains at about 8,600 ft on McGaffey Ridge, roughly 6 miles from home and ~1.5 miles above the valley area searchers covered.
Red flags (all reported)
| Flag | Detail | Other explanation |
|---|---|---|
| Wound | Entered near the base of the skull, right side, traveling right-to-left and upward. A death investigator called it 'atypical' for suicide | She shot left-handed (though right-handed), which changes what counts as typical |
| Range | Too little tissue to tell contact vs. distance; no bullet recovered | Skeletonization after about 11 months |
| Gun | Black Springfield handgun, registered; police won't say to whom | Whose it is decides a lot. Not released |
| Access | No known transport to a remote ridge 6 miles away | She walked; the terrain is reachable on foot in a day |
| Search gap | Found ridge-top, outside the valley search zone | Search areas are chosen by probability; ridges often aren't covered |
| Phones wiped | Both factory-reset | Deliberate act by her (planning) or by someone else. Forensics on the phones would tell |
| Husband's accounts | LA Mag reports his account of a gas-station stop was contradicted by surveillance, and his story about her boots changed (boots had fresh mud) | He has not been named a suspect or person of interest. Inconsistencies in a panicked spouse's account are common |
| Family | Hired a PI (Thomas McNally) and a lawyer; plan a civil suit against state police for mishandling | — |
Weighing it (E's read: "very fishy")
- Agreed, it's fishy. An undetermined manner, an atypical wound, an unnamed gun owner and wiped phones are real open questions.
- But the red flags point at a local investigation, not classified research. She was an administrative assistant, not a researcher. Nothing reported connects her death to her work. If it wasn't suicide, the evidence so far points toward people near her rather than toward the lab.
- So she fits the missing-scientists list mainly by employer and timing (four days after Reza), which is the weakest kind of link.
- What would decide it: whose gun it is, and the phone-wipe forensics (when, from where).
