NEW YORK (Reuters) -A woman who accused billionaire Leon Black of raping her two decades ago at the Manhattan mansion of disgraced financier and sex offender Jeffrey Epstein has ended her lawsuit against the Apollo Global Management co-founder. Cheri Pierson dismissed her claims in a so-called stipulation of discontinuance filed with a New York state court in Manhattan on Thursday. The dismissal is with prejudice, meaning Pierson cannot sue again, and she cannot recoup her costs.
