In 2000 Fulton was arrested in California along with his wife Tanya and Odysseus and Mahatma Landry, two of the sons of LVF member Muriel Gibson, on charges of possession of firearms and explosives, as well as drugs charges. When all charges not related to drugs were dropped campaigners seeking a full investigation into the murder of Rosemary Nelson asked the US Congress to investigate the circumstances surrounding the case. Fulton had left for the United States in 1999 soon after Nelson's killing, fuelling speculation that he had been involved.
