**Material uncertainties:**
– Rick Abath’s role is unresolved. Geoffrey Kelly’s assessment that Abath may have facilitated the theft is his personal investigative hypothesis, not a legal conclusion. Abath denied involvement and was never charged. He died in 2024.
– The current location of all thirteen works is unknown. No piece has been recovered.
– Whether the works are together or separated is not established.
– The Philadelphia connection (works moved there circa 2003–2004) is based on FBI statements made in 2013. Subsequent location is not publicly established.
– Valuations (“more than $500 million,” “$200 million for the Vermeer”) are estimates appearing in current reporting, not transaction prices.
– Geoffrey Kelly’s *Thirteen Perfect Fugitives* (2026) presents his investigative conclusions, not official FBI findings or legal verdicts.
– The Dutch Room’s scheduled reopening in 2027 was reported by A&E (updated July 2026). Timeline may change.
– Robert Donati’s murder (September 1991) remains unsolved.
– George Reissfelder’s death was ruled a drug overdose. Kelly has described circumstances as suspicious; no alternative cause established legally.
– Current investigation status (October 2026): FBI and museum describe investigation as active. No arrests. No art recovered.
– The $10 million reward’s current exact terms should be verified directly with the museum; conditions may have been updated.
