Las Vegas police arrested an Israeli national and seized more than 1,000 samples and laboratory equipment from a residential property after several people reported becoming “deathly ill,” according to court documents and local media. Authorities recovered freezers, a biosafety hood, centrifuge, and multiple vials; samples were flown to the National Bioforensic Analysis Center in Maryland for analysis. Prosecutors added weapons charges after the initial hazardous‑materials warrant; investigators are also exploring links to other cases and possible illicit activity such as counterfeit medicine production. The episode raises biosafety and enforcement questions about unregulated laboratory operations in residential settings and will draw attention from public‑health and biodefense stakeholders.
