The FBI has a trove of stolen art and no idea who the pieces belong to.
The collection was discovered upon the death of William M.V. Kingsland, who died without a will but with a large number of paintings, drawings, and some sculpture. Kingsland was a sort of mystery man, according to The New York Times. Those who knew him––or thought they knew him––had been told that the gentleman was a graduate of Groton and Harvard, had once been married to French royalty, and lived on Manhattan's Fifth Ave.
Kingsland was actually Melvyn Kohn, however, he didn't live on Fifth Ave., and he never attended either of the prestigious schools he claimed he had. When Kingsland-Kohn died intestate, his possessions were transferred by the Office of the Public Administrator to two separate auction houses to be sold.
As the pieces were being cataloged, it became apparent that many of the pieces were stolen approximately 40 years ago. The provenance of most of the paintings, and a bust worth about $1 million, has been obscured over time and the FBI is displaying them online to see if anyone will step forward to claim them.
As for Kingsland/Kohn's heirs, a number of first cousins and an uncle have popped up claiming a piece of the multi-million dollar estate.
