WEST PALM BEACH — The ghosts of Shelly Pearson’s past just won’t rest. In the year 2000, Pearson thought she had finally established a fitting tribute to her own relatives and other Lithuanian Jews who were slaughtered in the Holocaust. Through her International Foundation for the Arts, based in West Palm Beach, she had installed a memorial to those victims in the Lithuanian capital of Vilnius. An elegant metal modern sculpture called “The Flame of Hope” was erected in the courtyard of the building that had once housed the Judenrat, the office established by the Nazis to determine the fates of the country’s Jews. It was a fitting location, and because a children’s theater stood nearby, it had another advantage. “Lots of kids will see it,” Pearson said at the time. “That will be good.”
