Donati and Reissfelder participated through a Boston organized-crime network

Former FBI case agent Geoffrey Kelly's reconstruction places Bobby Donati and George Reissfelder near the center of the theft and subsequent handling, citing Donati's interest in the eagle finial, Reissfelder's alleged getaway-car connection, and a family recollection concerning Chez Tortoni. The FBI publicly said in 2013 that it had identified the thieves but did not officially name them; neither man was charged, and the works remain missing.

A guard or insider knowingly assisted the entry

The inside-assistance theory points to the guard's protocol violations, including admitting the purported police and an unusual door opening shortly before the robbery. Rick Abath denied involvement and was never charged. Footage released from the previous night generated additional speculation, but later investigative review found that visitor unrelated to the theft.

The thieves removed the museum's security videotapes before leaving. No usable recording of the thieves inside on March 18 is publicly available; footage released in 2015 came from the previous night.

The works passed through Guarente to Gentile

One custody-chain theory holds that Robert Guarente obtained some works and transferred them to Robert Gentile. Searches and a handwritten list sustained investigative interest, but repeated efforts recovered no art and did not establish the original thieves or a verified chain of possession.

The Youngworth–Connor lead reflected genuine possession

Claims promoted in the 1990s suggested that associates of incarcerated art thief Myles Connor could return the paintings for money and immunity. A reporter was shown a purported Rembrandt, but no Gardner work was authenticated or recovered and negotiations collapsed.

Evidence
Rembrandt van Rijn's Christ in the Storm on the Sea of Galilee was taken from the Dutch Room during the theft and remains missing. It is one of the 13 objects listed by both the museum and FBI.
