Daniel A. McGuinness is a 2006 graduate of the New York University School of Law.  His practice focuses on criminal defense and public interest representation.  Mr. McGuinness was second-trial chair for the case of United States v. Thomas Gioeli, in which Thomas Gioeli was found not guilty of six murders.   In that case, he oversaw a team of lawyers reviewing over twenty years of government evidence, including hundreds of hours of eavesdropping recordings.  Mr. McGuinness also cross-examined civilian and law enforcement witnesses.  He is an excellent legal writer who constantly seeks to develop new theories and approaches to the law.  For example, Mr. McGuinness convinced the Gioeli Court to admit evidence that a federal informant had sexual contact with the two women after the informant had murdered their boyfriends.  Mr. McGuinness  worked as a supervising attorney overseeing teams of lawyers reviewing documents in connection with the landmark Vioxx and Vytorin litigations.  Daniel McGuinness also served as a pro bono legal counsel at the School Crimes Bureau in the King's County District Attorneys Office where he prosecuted crimes for theft, assault, and weapons possession.
