DA Madeline Singas

Biography of Acting District Attorney Madeline Singas:

Madeline Singas is a career prosecutor who brings a commitment to justice, compassion, and integrity to her job as Acting District Attorney of Nassau County. Upon taking office in January 2015, Singas became the first Greek-American and the second woman to become the top law enforcement official of Nassau County. 

For the last two decades, Singas has prosecuted violent criminals, including those who target the most vulnerable members of our society – women, children, and the elderly. Appointed chief of the newly-created Special Victims Bureau in 2006 by Nassau County District Attorney Kathleen Rice, Singas instituted changes that held more offenders accountable and kept more vulnerable people safe.

In that role, Singas successfully prosecuted some of the county’s most notorious crimes, including securing a rare First Degree Murder conviction and life sentence against Leonardo Valdez Cruz for the torture and murder of his girlfriend, Joanna Bird. 
As Nassau County’s Chief Assistant District Attorney since 2011, Singas supervised the prosecution of approximately 30,000 criminal cases each year, and helped design and implement numerous groundbreaking programs in cases involving adolescent offenders, veterans, and those who suffer from mental illness or drug abuse. She has overseen tough prosecutions of financial criminals, corrupt public officials, and drunk drivers who threaten the safety of everyone in our community.  

Singas also played a major role in securing nationwide SAT reforms, forming a groundbreaking collaboration with the SAFE Center to help victims of domestic and sexual abuse and victims of human trafficking, and overseeing the conviction at trial of Darrell Fuller, who was sentenced to life in prison without the possibility of parole for murdering a police officer and an innocent motorist in 2012. 

Beginning her career in the Queens District Attorney’s office in 1991, Singas quickly assumed a leadership role in the Domestic Violence Bureau, prosecuting hundreds of cases in New York City’s second-most populous borough.

Singas lives in Manhasset with her husband and 12-year-old twins. A native of Astoria, Queens, she is a proud first generation Greek-American born to a family committed to community, faith, and education. 

She is a graduate of Bronx High School of Science, Barnard College at Columbia University, and Fordham University Law School.
