In 1997, art dealer William Youngworth offered to broker the return of the works and brought a paint sample that he claimed came from one of the stolen Rembrandts. FBI analysis determined the sample was not consistent with the stolen Rembrandt. The offer came to nothing.
In 2012, a search of Robert Gentile’s home produced police hats and badges, $20,000 in cash, weapons, and a handwritten list of the stolen works with estimated black market values beside each piece. No paintings were found. Gentile failed a polygraph. He stopped cooperating. He denied everything until his death in 2021.
In 2013, the FBI announced that it believed the stolen works had been moved through Connecticut and Philadelphia in the early 2000s.
In 2015, the FBI released surveillance footage—carefully noted as being from a different night than the theft—of a man outside the museum. The man was later cleared of involvement. The FBI also named George Reissfelder and Leonard DiMuzio as the primary suspects who had entered the museum. Both were dead.
In 2017, the reward was raised to $10 million.
Geoffrey Kelly led the FBI’s Gardner investigation from 2002 until his retirement in April 2024. He has publicly stated his investigative conclusions in interviews and in his 2026 book: Reissfelder and DiMuzio as the thieves, Merlino as the organizer, Abath as potentially complicit. These are his assessments based on his investigative work, not official FBI findings and not legal verdicts. He believes the works still exist.
