Law Enforcement History

Director DeMaio followed in his father’s footsteps and began his career with the Newark Police Department in 1986, at the age of 19.   Director DeMaio worked his way through the ranks of the Department at a rapid pace, becoming the youngest person to achieve each of the ranks he was promoted to.  As a Patrolman he worked in the City’s North District and the prestigious Tactical Force.  In 1990, he was promoted to Detective where he worked in the Major Crimes Bureau and the FBI Violent Crimes Task Force.  In 1992, Director DeMaio was promoted to Sergeant where he worked in the North District and the Narcotics Division until 1995 when he was promoted to Lieutenant.  As a Lieutenant he worked again in the North District and as Executive Officer of the East District.  In 1999, Director DeMaio was promoted to the rank of Captain where he commanded the South and North Districts, developed and commanded the Safe City Task Force and served as Chief of Staff to the Chief of Police.  In 2005, he was promoted to Deputy Chief where he served as Chief of Staff, Chief of Detectives and Chief of Operations for the Department.


Director DeMaio is a graduate of Hanover Park Regional High School in East Hanover and attended Morris County College.  During his law enforcement career he has attended numerous police management courses through the Police Executive Research Forum, the Senior Management Institute for Policing, and the Kennedy School of Government at Harvard University and Boston University. Recently, Director DeMaio graduated session 36 of the FBI National Executive Institute, Quantico Virginia.  



Director DeMaio was awarded with the Columbian Foundation Humanitary Award on October 20, 2012. In recognition of his successful career as a proven and competent leader with exceptional management skills and extensive knowledge in strategic policing, Mayor Cory Booker chose Samuel to lead the Newark Police Department. On May 3, 2011 Samuel was appointed as Acting Police Director until August 18, 2011 when he received the City Council's first ever unanimous vote, becoming the City's 16th Police Director. At the time of his appointment Director DeMaio was faced with daunting increases in the City's violent crime levels. In response Samuel implemented a complete reorganization of the Department. He created several innovative crime prevention/reduction initiatives and reinstated numerous police units including: the motorcycle squad, the mounted unit, the aviation unit, the marine unit, the community affairs unit, and the clergy affairs unit. By year's end Director DeMaio transformed a 45 percent increase in murders and a 55 percent increase in shootings into 15 percent reduction in murder and 18 percent reduction in shootings. Samuel once again demonstrated his ability to produce positive results in the face of extreme adversity. Despite drastic reductions in financial resources and manpower Samuel's accomplishments have undoubtedly prevented countless tragedies and improved the quality of life for all Newarkers.

In addition to increasing productivity within the Department while decreasing sick time the Department has also experienced a reduction in complaints against police. Director DeMaio has not only demonstrated a strong commitment to protecting the community but serving it as well with implementation of the NPD Memorial Scholarship Fund which gives scholarships to Newark kids entering college and private high schools. The scholarship fund has raised over fifty thousand dollars in its' first year with scholarships given in the names of officers who died in the line of duty as active Newark police officers.

Police Director Samuel DeMaio has dedicated his life to public service. He has enjoyed a highly distinguished career and continues to earn the respect and admiration of the law enforcement community and the greater Newark community which he serves proudly.
