Overview
- Federal, state and local teams — including the FBI, Irvine police, Orange County Fire Authority and the California National Guard’s WMD civil support unit — have conducted a multi‑day investigation at a rental home in Irvine.
- The inquiry started after a maintenance worker reported a garage laboratory to the landlord, and investigators collected materials and writings that prompted further forensic analysis.
- An unconfirmed indication of a possible nerve agent was reported by an unnamed source to media outlets, and authorities have not publicly identified any agents found.
- The resident, Amalvin Fritz, 17, a UC Irvine student, says he was conducting benign chemistry related to cubane molecules for disease research and posts instructional videos on YouTube.
- A chemistry professor cautioned that chemicals cited in the teen’s videos and home setup — including acetone, Epsom salts, cyclooctatetraene and isopropylmagnesium chloride — should be used only in proper labs; no arrests or charges have been announced, and the California Department of Toxic Substances Control is handling cleanup while the family remains displaced.
