Stojkovic was one of the prisoners of the Sheena Island prison, awaiting to be experimented on to extract β Hetero Nonserotonin, a chemical produced by the brain that is required for the development of the Hypnos-T Type.
He stayed alive long enough to be organized into the 20 membered prison group attempting to escape in October 1998, and was tasked with gathering weapons with Yoshikawa. It is unknown whether the two succeeded in gathering the weapons, but either way they were caught by the prison guards. The commander of the Umbrella facilities on the island, Vincent Goldman, shot each escapee personally and had the local police chief file a false report to Umbrella, claiming that the prisoners died in a mass-suicide. In protest, local people began collecting evidence on Goldman's crimes in order to report him to Umbrella and be rid of him once and for all.
