Kept under 24-hour guard at Fort Tyson in an easily-recognizable platinum container, the isotope 16 was stolen by Spider-Man, who was at the moment struck with amnesia, as instructed by his partner in crime Doctor Octopus. It was needed to perfect Nullifier, but Doc Ock couldn't use it before being defeated and taken into custody by the military.
