Three people have been charged with embezzling more than $750,000 from a New York nonprofit organization and attacking its executive director with a caustic chemical to conceal the alleged theft.

Prosecutors say Kim Williams, Pia Louallen and Jerry Mohammed were charged Tuesday in a 65-count indictment.

Investigators say Williams was an accountant at Hospital Audiences Inc. and stole more than $600,000 from the Queens nonprofit between 2012 and 2015. The indictment says she also provided Louallen with an additional $150,000.

Prosecutors say Williams enlisted Mohammed to throw a caustic substance at the nonprofit's executive director, Rev. D. Alexandra Dyer, to conceal the alleged theft. Dyer sustained severe burns and has undergone multiple surgeries.

It's unclear if Williams or Mohammed have attorneys who could comment on the charges. Louallen's defense attorney says his client denies any wrongdoing.
