Mary Soto

Former Mamaroneck Library Employee Charged with Grand Larceny in the Third Degree

Last February, the Mamaroneck Public Library Board of Trustees became aware of financial irregularities within the Library’s business office. In response, swift action was taken – a comprehensive financial forensic audit was initiated, focusing on potential misappropriation and the examination of all Library accounts. The outcomes prompted the Westchester District Attorney to launch an independent investigation.


The District Attorney has concluded their investigation and arrested former employee Mary Soto. She has been charged with grand larceny in the third degree for the theft of $44,769 from 2016-2023. We are hopeful that the judicial process will bring accountability and a satisfactory resolution for Mamaroneck’s taxpayers.


We understand the community has questions and concerns about these events. We appreciate your patience and assure you that we are diligently working to furnish complete and accurate answers. Open communication is vital, and we pledge to keep you informed of any additional developments.


The Library Board acknowledges the continuing potential for difficult financial decisions in the future. Nevertheless, the Mamaroneck Public Library stands unwavering in its century-long commitment to serving the community. We understand the importance of maintaining the public’s trust and will continue to work closely with the Village, the public, and relevant agencies to safeguard the integrity of our beloved Library.


“The library appreciates the ongoing support of our community and remains confident that, together, we will overcome these challenges and emerge stronger than ever,” said Director Jennifer O’Neill. “We are grateful to Renee Hassel, Westchester County Assistant District Attorney of the Public and Law Enforcement Integrity Bureau, and her team, for their commitment and professionalism in this matter.”
