When Tom DaCosta began his training with the New York City Police Department in the late summer of 2001, he expected to spend months mastering the basics of municipal law enforcement in a controlled classroom setting. Instead, merely two months into his new career, the recruit found himself standing guard inside a desolate Grand Central Terminal just hours after the World Trade Center towers collapsed.
The transition from student to frontline sentry was abrupt and unforgettable. On September 12, DaCosta observed families weeping and posting fliers searching for missing loved ones across the transit hub. What had once been a bustling center of daily commuter life had suddenly been transformed into what DaCosta described as a quiet, cavernous mausoleum, where officers stood watch against the terrifying prospect of follow-up terrorist attacks.
For DaCosta, a North Haven resident who is now 56 years old, public service was already a deeply ingrained part of his identity. Before joining the police department, he had served for nine years as an artilleryman in the United States Marine Corps. He initially enlisted in 1988 during peacetime seeking personal development and discipline, but his military career eventually took him into eight months of combat during the Gulf War between 1990 and 1991.
Following his discharge from the military, DaCosta set his sights on civilian policing, a career path inspired by his family background. His father had previously served as a police officer in East Haven, instilling in him a strong desire to pursue a future in law enforcement.
While living in West Haven, DaCosta received word from a high school friend who was already serving on the force that the NYPD was actively recruiting. DaCosta applied and earned a spot in an unusually large academy class comprising approximately 1,800 recruits. To accommodate such a vast intake, the department split the class into two cohorts that rotated between daytime and nighttime training schedules every week.
During the fateful second week of September, DaCosta was assigned to the night shift and had returned to his Connecticut home at approximately 2 a.m. on September 10. The following morning, his wife, Amy, who worked as a research administrator at the West Haven VA Hospital, paged him immediately after the first plane struck the North Tower.
DaCosta initially planned to return her page after getting out of bed, but within fifteen minutes his pager went off repeatedly and his home phone began ringing continuously as news broke that a second aircraft had hit the South Tower. Recognizing that the nation was under attack, he reported for duty and within a few hours was stationed in the Bronx awaiting operational deployment.
His unit was quickly dispatched to secure Grand Central Terminal, where DaCosta spent the next month patrolling the facility before being ordered back to complete his interrupted curriculum at the police academy.
While DaCosta was tasked with transit security, many of his academy classmates were sent directly to the pile of toxic debris at Ground Zero. Those recruits spent grueling weeks digging through rubble in search of survivors and recovering the remains of victims, assignments that exposed them to dangerous airborne toxins and long-term medical complications.
The consequences of that work proved catastrophic over the ensuing decades. DaCosta noted that roughly 150 of his academy classmates have since lost their lives to serious, unexplained medical conditions directly linked to their recovery efforts at the disaster site.
Looking back at that chaotic period, DaCosta likened the experience of having academy training halted by a national catastrophe to a recruit being pulled out of military boot camp, deployed directly into a combat zone, and then returned to basic training to finish routine coursework.
The unprecedented assault on New York City fundamentally reshaped the mission and operational philosophy of the entire police department. While recruits had previously focused heavily on combating petty street crimes, theft, and public disorder, counterterrorism and infrastructure security instantly became the agency’s overriding priority.
DaCosta went on to dedicate 24 years of service to the NYPD Transit Bureau, helping modernize the department's specialized security capabilities. Over his career, he worked alongside an explosive-detection Labrador named Skeeter and witnessed the department's bomb-sniffing canine unit expand from nonexistent to a force of 50 specialized dogs. He eventually retired at the rank of deputy inspector, overseeing a command of 80 transit officers.
Following his retirement from active police work, DaCosta turned his focus back toward supporting former service members. Today, he leads New Haven VFW Post 12150 as its commander. The post, originally founded in 2015 to serve the needs of post-9/11 veterans, centers its efforts on direct veteran assistance and local community service projects.
Reflecting on the era, DaCosta observed that the intense emotions following the attacks—where national shock and grief quickly turned into collective anger and resolve—played a significant role in motivating countless young Americans to enlist in the military.
Decades after the attacks, DaCosta remains concerned that historical awareness of the tragedy is fading among younger generations who did not live through it. He emphasizes that the aftermath of September 11 remains an ongoing reality, as first responders and survivors continue to suffer and die from related illnesses to this day.
