概要
A county surveyor found nine sealed transport containers half-buried under a collapsed fence, their seals intact and inventory logs claiming nothing was missing-yet the shipment was short by a precise, collective weight. This episode reveals how a missing 430+ grams of rare laboratory compounds vanished without a broken seal, forged credential, or falsified inventory; who engineered the metronomic access pattern, and why weight - not presence - became the only clue?
In this episode, we tell what happened at Norwell University's Division of Materials Research, how the stockpile and badge logs behaved, and how investigators traced an 18‑month pattern of access that left no conventional evidence. What did a heating and ventilation technician do during thirty‑two undocumented visits that no one flagged?
Location: Margrave Hall, Norwell University
Person: Stanley Dalton
Investigator: Scott Cook
Deficit: more than 430 grams
Stockpile value: approximately $2.3 million
- Nine sealed transport containers were found half-buried under a collapsed cedar fence, 412 feet from the laboratory rear entrance.
- The laboratory stockpile held seventeen rare elements and compounds, collectively valued at approximately $2.3 million.
- Badge logs show Gregory Sheridan entered 73 times over 18 months; 32 of those visits had no attached work orders and averaged 20-40 minutes each.
- Osmium tetroxide had no human-hand log entry in 14 months prior to the discovery.
- Weighing by Barbara Yuen found a cumulative deficit of more than 430 grams across nine compounds.
