An unsolved 23-year-old art heist in Boston may have local connections. In the years following the theft of 13 works worth $500 million from the Gardner Museum — including pieces by Rembrandt, Degas and Vermeer — the stolen art may have been brought to Philadelphia to be fenced. "The Gardner heist is in the minds of most art historians as one of the most spectacular and heartbreaking art thefts," said art historian Therese Dolan of the Tyler School of Art. "Who could afford [these pieces]? Who would want them? Who would have the kind of personal security in their homes to keep them?"
