A Catholic man who served as an usher at his Brooklyn parish before he was killed in a brutal attack in a city subway is being remembered as a “good soul” with a “tremendous” faith in Christ.
Sixty-four-year-old Nicola Tanzi was killed on Oct. 7, when police say 25-year-old David Mazariegos beat him to death in the Jay Street-MetroTech station in Brooklyn.
He later died at New York-Presbyterian Brooklyn Methodist Hospital. New York City Police Commissioner Jessica Tisch described the attack as “horrific.” Police were able to apprehend the suspect using photos and a physical description transmitted through their phones, Tisch said.
Mazariegos has reportedly been arrested multiple times before. U.S. Transportation Secretary Sean Duffy said on X that state Gov. Kathy Hochul “has blood on her hands” over the death.
“Nicola Tanzi’s life was taken by another repeat offender roaming New York’s streets freely,” Duffy wrote. ”New York needs leaders who will back the blue and make America’s transit system safe again.”
Victim mourned as a ‘simple, good person’
Those who knew Tanzi have mourned his death in the days following his murder.
Deacon Anthony Mammoliti told CNA in an interview on Oct. 10 that Tanzi was “probably the most Christ-like parishioner I’ve encountered.”
Mammoliti serves at St. Dominic’s Parish in Bensonhurst where Tanzi attended. Tanzi served as an usher there at the Italian Mass for at least 10 years, the deacon said.
“He was a man who would give of himself,” Mammoliti said. “In his civilian job, he would often, without hesitation, switch shifts to allow married colleagues to have family time. When I engaged with him in the parish, it was always with a congenial smile.”
Tanzi would regularly greet elderly parishioners with a “Buon Giorni!” and “Come Stai!” while holding the door for them, Mammoliti said.
The deacon said the parish is in shock over the news.
“We’re all in a state of disbelief. The old expression, ‘Bad things happen to good people,’ that’s the first thought that came to mind,” he said.
Deacon John Heyer of Sacred Hearts and St. Stephen Catholic Church in the city’s Carroll Gardens neighborhood told CBS News that Tanzi was “definitely a good person. Like, a simple, good person.”
“[He was the] type of guy who went to work and came home and was part of different community organizations,” Heyer said. “Especially those related to his family’s heritage and roots in Mola di Bari, Italy.”
Mazariegos, the suspect in the killing, reportedly has multiple criminal cases open against him throughout the city. He allegedly admitted to the killing afterward.

Mammoliti said Tanzi, a “tremendous man of faith” with a “good soul,” had he survived the assault, would have forgiven his assailant. “He would have done what he normally did, which was to be a good Christian,” he said.
“Your first initial reaction [upon hearing the news] is, you know, eye for eye, tooth for tooth,” the deacon admitted. “But we’re called to be people of faith. We’re called to emulate the teachings of the Gospel.”
“We would honor Mr. Tanzi if we would live up to what Jesus teaches us, which is to forgive our enemies.”
