DOI continues to spearhead a tort fraud task force that includes the Law Department and the City Comptroller's Office. The task force's goal is to identify fraudulent claims against the City, prevent them through a combination of criminal prosecutions, affirmative litigation and changes in procedures and reduce the opportunity for fraud. In 2002, the task force's work includes the criminal prosecution of a taxi driver who filed a $50 million lawsuit against the City erroneously claiming he was beaten by Taxi and Limousine Commissioner inspectors.

DOI works diligently to restore tens of millions dollars to City coffers for restitution and loss prevention from all of its cases.

In October 2006, DOI issues public findings concerning fraud and mismanagement at the City-funded Gloria Wise Boys & Girls Club. DOI found that Gloria Wise executives fraudulently siphoned hundreds of thousands of dollars from the nonprofit, including giving funds to an executive's private business venture; and routinely falsified records such as how public funds were spent to medical records of preschool children, including whether the children in the Gloria Wise nursery schools were actually vaccinated. Executives also attempted to conceal their misconduct and obstruct DOI's investigation by fabricating documents and misrepresenting the facts when questioned under oath. As a result of this investigation, Two of the executives, Charles Rosen and Jeff Aulenbach, pleaded guilty to Grand Larceny in the Third Degree and Obstructing Government Administration in the second degree. Rosen also pleaded guilty to Forgery in the Second Degree.

Following an 18-month investigation, DOI issues an exhaustive examination of 11 child deaths and one near fatality, revealing problems with the New York City Administration for Children's Services ("ACS") investigations and recommending that ACS strengthen its investigations of serious child abuse cases by hiring 100 additional Investigative Consultants. DOI conducted hundreds of interviews and undertook a comprehensive review of all relevant documents. The agency used its subpoena power when necessary and studied the 140-year history of ACS and its predecessor entities in connection with the investigation of serious abuse or neglect. DOI's conclusion was that vital child welfare investigations need to be thoroughly conducted and call for two types of expertise: the trained social worker and the seasoned investigator. Read about The Department of Investigation's Examination of Eleven Child Fatalities and One Near Fatality.


In October, DOI holds the National Watchdog Conference at Gracie Mansion, a day-long national conference that drew City, state and federal Inspectors General and integrity scholars to share various approaches and methodologies for preventing and eliminating public corruption and identifying best practices.

DOI closed out the year with a record 848 arrests. DOI's work in 2008 included a variety of cases focused on fire and construction safety and wrongdoing at publicly-funded nonprofits. DOI dedicated substantial resources to intensive investigations of the fatal crane collapses at 51st and 91st streets, the fatal fire at 130 Liberty Street and the investigation into discretionary funds at the City Council.


DOI received a tip on its hotline right after inmate Christopher Robinson was killed in October 2008, which led to the discovery of organized beatings of inmates and, in January 2009, to the indictment of three correction officers and 12 inmates on charges of participating in an assault conspiracy. DOI's investigation found that adolescent inmates were beaten for such things as commissary money and use of the telephone.

In July 2009, former New York City Councilman Miguel Martinez pleads guilty to federal fraud and money laundering charges as a result of a joint investigation by DOI and the United States Attorney's Office for the Southern District of New York. Martinez submitted false invoices to the City and diverted funds from nonprofit organizations that resulted in a personal benefit to him of more than $100,000. Martinez resigned from public office and was sentenced to a five-year federal prison term.

As the result of an extensive investigation by DOI, the Federal Bureau of Investigation, the U.S. Attorney's Office for the Southern District of New York and other law enforcement agencies, former labor leader and New York State Assemblyman Brian McLaughlin is sentenced to 10 years in federal prison for racketeering and was ordered to pay nearly $846,000 in restitution and forfeit more than $3 million. In a related case, a former Queens electrical contractor pleaded guilty and was sentenced to three months in prison for illegal payments to the former labor leader and State assemblyman.


DOI's focus on not-for-profit vendor fraud and the misuse of discretionary funding leads to successful and long-term results. Commissioner Rose Gill Hearn formed a special unit around this issue in 2007 after DOI conducted several investigations that exposed fraud at nonprofits by insiders and public officials. The unit consists of forensic auditors and investigators who follow the money trail. As of 2010, the unit's work results in more than 30 arrests and convictions.
In a case that rocked the concrete testing industry and the construction industry, Testwell, a concrete testing company, and its principals were convicted on charges stemming from their widespread falsification of concrete test results. The case exposed the enduring and widespread effect that false construction-related reports can have on public safety and confidence. The company was ordered to pay more than $1.7 million in restitution and two of its principals were sentenced to prison terms.

Two significant, ongoing DOI investigations culminated in 2010:

  • Using DOI's subpoena power and the skill of its investigators and auditors to trace the money, DOI exposed a massive fraud scheme in the implementation of the City's computerized timekeeping system. The investigation led to federal felony charges against six individuals, including several consultants on the project. The ongoing investigation included the continuing pursuit of assets tied to the multimillion-dollar scheme and resulted in eight convictions. Read DOI's Statement on Prison Sentence for FDNY Supervising Inspector Who Participated in Million-Dollar Day Care Fraud.
  • Investigators exposed a prolific criminal network exploiting the City's publicly-funded and regulated day care program that touched at least three City agencies -- Human Resources Administration, Department of Health and Mental Hygiene, and Administration for Children's Services -- and more than 30 day care centers. In all, 15 defendants were convicted, including seven City employees and eight day care owners. This investigation demonstrated DOI's unique role: pursuing the criminal investigation and allowing it to step in quickly and work with City agencies to safeguard the public. Even as the criminal probe advanced, DOI was there to immediately close the fraud gaps it found at the various City agencies, recommending unannounced site visits at the day care centers to confirm that the children for whom the City was paying were actually in attendance, rotating work locations of City employees to reduce the risk of fraternization between staff and clients, and conducting audits of files. In addition, DOI alerted the appropriate City Health officials to the need for prompt and thorough inspections of the day care facilities associated with the investigation. More than 20 day care centers were closed due to violations that were part of the fraud exposed by the investigation. Read DOI's Statement on Prison Sentence for FDNY Supervising Inspector Who Participated in Million-Dollar Day Care Fraud.


An outgrowth from a previous DOI corruption case led DOI to join forces with its federal law enforcement partners to expose a large-scale bribery and kickback scheme involving City Department of Housing and Preservation (HPD) programs, resulting in the indictment and arrest of an HPD Assistant Commissioner and six HPD developers and contractors. Because DOI's legal powers enable investigators access to City properties, books, and records, DOI was able to obtain and review key records such as personnel records, project files, and thousands of HPD emails covertly.

Four years ago, DOI discovered a host of delinquent fire code violations throughout the five boroughs on commercial properties and apartment buildings relating to such fire safety issues as blocked egress, dangerous wiring, and improperly stored flammable materials. Working with the City Fire Marshals, DOI began an annual initiative (undertaken throughout the year, including a targeted approach in October, which is Fire Prevention Awareness Month) to bring these violators who had failed to respond to a criminal summons to court. The initiative has the result of ensuring that the unsafe conditions are remediated. The effort was expanded in 2011 to include warrants involving building violations. DOI worked with the City Department of Buildings ("DOB") to track down and arrest violators who ignored or refused to remedy violations, including in illegal Single Room occupancies. The coordinated initiative, spearheaded by DOI, brought charged safety code offenders to justice, and highlighted the legal obligation of property owners and all persons to maintain safe conditions and respond in court to the City's legal notices of violations requiring corrective action.


In March, Mayor Michael R. Bloomberg, DOI Commissioner Rose Gill Hearn, and U.S. Attorney for the Southern District of New York Preet Bharara announce the prime contractor on CityTime, Science Applications International Corporation ("SAIC"), will pay $500 million in a settlement of charges that SAIC engaged in fraud resulting in cost overruns to implement the City's computerized timekeeping system.

Peters, former Chief of the Public Corruption Bureau and Deputy Chief of the Civil Rights Bureau with the New York State Attorney General's Office, to be DOI Commissioner who takes office on February 18, 2014. Read about Commissioner Peters.

Commissioner Peters announces the appointment of Philp K. Eure as New York City's first-ever Inspector General for the New York City Police Department, fulfilling Local Law 70 that empowers the DOI Commissioner to "investigate, review, study, audit and make recommendations relating to the operations, policies, programs and practices, including ongoing partnerships with other law enforcement agencies, of the new york city police department with the goal of enhancing the effectiveness of the department, increasing public safety, protecting civil liberties and civil rights, and increasing the public's confidence in the police force, thus building stronger police-community relations."

DOI launches a probe into violence, contraband smuggling, and evidence tampering within the City's jail system, including on Rikers Island, the City's main jail complex situated in the East River between Queens and the Bronx. In 2014, DOI arrests nearly one dozen Correction Officers, supervisors and other staff, as well as more than 30 inmates, on an array of charges; and issued a report that details a large-scale undercover investigation exposing serious problems with security screening protocols and contraband smuggling on Rikers Island. As a result, the City Department of Correction (DOC) agrees to enhance its security procedures, including for the first time implementing drug-detecting dogs at staff entrances, assigning Special Operations Division ("SOD") to oversee security at staff entrances, and the consideration of upgrading DOC search protocols to the standards employed by the federal Transportation Security Administration ("TSA"). This investigation continues into 2015 with significant results.

DOI and the New York County District Attorney's Office announce an indictment in a construction site safety fraud case on charges of falsifying site safety inspections at multiple active construction sites in Manhattan.

Read the related press release on the sentencing of Richard Marini for facilitating fraudulent site safety inspections at multiple construction sites in Manhattan.


DOI issues two more reports focused on problems within the City's jail system. One report focused on DOC recruitment and hiring procedures, uncovering a deeply flawed system in which more than a third of officers were hired despite numerous corruption and safety hazards, including multiple prior arrests and convictions, prior associations with gang members or relationships with inmates. The report also found the Applicant Investigation Unit (AIU), which is responsible for screening potential recruits, relied on antiquated and haphazardly filed paper personnel documents and had little to no access to software necessary to perform basic background and credit checks. As a result, DOC replaced both its Director and Deputy Commissioner responsible for oversight of the AIU and responsible for the hiring of the applicants DOI reviewed, assigned additional staff to the screening process, and committed to an aggressive set of reforms in this area.

A second report issued during 2015 found acute failures by Corizon Health Inc. ("Corizon"), a private company contracted by the City to provide medical and mental health services in Rikers Island jails, both in the contractor's hiring processes and treatment of mentally ill inmates. The investigation also revealed the DOC and Department of Health and Mental Hygiene ("DOHMH"), both responsible for supervising Corizon, failed to properly oversee the company's hiring and supervision of clinical staff.

Along with the New York County District Attorney's Office and the NYPD, DOI announces the arrest of more than four dozen individuals – including 11 City Buildings Department and five City Housing Preservation and Development employees – in a widespread bribery scheme. The investigation began as a DOI undercover operation in which a Housing inspector alerted DOI about a bribe offer. The investigation found irregularities that raised questions about how buildings inspections had been conducted and led to the discovery of approximately $450,000 worth of alleged bribes in numerous schemes. Read the related release on the indictment of 50 defendants involved in widespread housing fraud and bribery schemes.

DOI and the NYC Health + Hospitals sign a Memorandum of Understanding ("MOU") giving DOI control over a new Office of the Inspector General for NYC Health + Hospitals ("NYC Health + Hospitals OIG").

On November 16, 2018, Mayor Bill de Blasio nominated Margaret Garnett to serve as Commissioner of the Department of Investigation. At the time of the nomination, Ms. Garnett was serving as Executive Deputy Attorney General for Criminal Justice in the office of the New York State Attorney General. Prior to her tenure at the state Attorney General’s office, Ms. Garnett spent 12 years as a federal prosecutor in the office of the United States Attorney for the Southern District of New York, where she was responsible for prosecuting gang violence, racketeering, organized crime, violent crime, international terror, and tax fraud.

New York City Council confirmed Ms. Garnett as DOI Commissioner on November 28, 2018. At that time, Commissioner Garnett issued the following statement:

New York City deserves an independent, fair, and trustworthy Department of Investigation, dedicated to the highest standards. Today, I am honored and proud to become Commissioner of DOI and preserve its legacy of ensuring integrity in the City and inspiring the people’s confidence in their government. I thank the Mayor for his nomination and the City Council for its thorough questioning and confirmation. As a prosecutor and public servant, who has dedicated my career to conducting independent investigations, I understand that a DOI Commissioner must lead by example and set an exceptional standard; it is a responsibility that I will carry with me every day. Over the next several weeks, I am looking forward to meeting all of the career professionals at DOI – the investigators, the lawyers, the auditors, the analysts, and the administrative staff – who are the core of the agency. There is much to be done and I am grateful for the opportunity to roll up my sleeves and get to work for the people of New York City.
