The San Diego Museum has returned a painting in its collection to Mexico. The painting, ‘Expulsion From the Garden of Eden,’ painted in 1728 by an unknown artist, was cut from a frame and stolen in 2000 from a church in San Juan Tepemasalco, in the Mexican state of Hidalgo. “Many questions remain unanswered as to how the painting ended up at the museum. No arrests have been made despite a two-year investigation into how the artwork was smuggled into the United States.
