Escalating Violence in Brooklyn Case

David Mazariegos, who had a history of minor offenses, reluctantly had his bail lowered just months before he allegedly killed a security guard outside a subway station in Brooklyn. The presiding judge, Robert Rosenthal, chillingly anticipated the potential for increased violence during a July hearing.

This revelation came from court transcripts after prosecutors couldn’t secure a more severe charge against Mazariegos, 25, whose actions later led to the death of Nicola Tanzi, aged 64.

During that hearing, Rosenthal noted that Mazariegos had an extensive record of mostly minor crimes until the assault in late June, which he pointed out “has increased in severity over time.”

Mazariegos’ charges were eventually downgraded to a misdemeanor. Despite that, prosecutors requested the same $2,500 bail as when he was initially charged with a felony, according to court records.

Public Defender Gretchen Rieser contended that Mazariegos should be released without bail, emphasizing he was not a flight risk and lacked any violent past at the time. However, Rosenthal spent significant time contemplating this request.

He acknowledged that it was Mazariegos’ first violent crime but expressed concern that the seriousness of the charges suggested a pattern of behavior that was not likely to lead to a simple return to court.

Ultimately, Rosenthal lowered Mazariegos’ bail to $1,000, preparing to release him. However, during this time, Mazariegos allegedly escalated his violence, culminating in the fatal attack on Tanzi outside the Jay Street Metrotech station.

Diana Florence, an independent candidate aiming to replace Manhattan District Attorney Alvin Bragg, was criticized for not keeping Mazariegos incarcerated. She remarked that the tragedy was avoidable, stating, “Nicola Tanzi didn’t have to die.”

In response, Richard Fife, a spokesperson for Bragg’s re-election campaign, accused Florence of manipulating the situation for political gains.

Previous court records indicate prosecutors had charged Mazariegos with assault after he allegedly punched a security guard outside a theater on June 24, marking a significant escalation from his earlier offenses that included fare evasion and graffiti.

During his July 2 arraignment, Mazariegos faced serious bodily injury charges, prompting a request for $5,000 bail. Rieser argued he should be released on supervised release, citing his work with the Youth Justice Network, which helps young individuals in the justice system.

She suggested that even if convicted, he was unlikely to face prison time, characterizing monetary bail as effectively a prison sentence. Judge Julieta Lozano ultimately set bail at $2,500, noting Mazariegos had multiple open cases and a prior arson conviction.

By July 8, the charge against Mazariegos was changed to a misdemeanor as the injuries to the 65-year-old victim did not qualify for a felony charge, but prosecutors still sought a $2,500 bail and added another misdemeanor assault charge. Rieser maintained that Mazariegos was working towards turning his life around.

His attorney mentioned that Mazariegos had recently completed an internship with an animation project and had been involved in community services, including a literacy program.

However, Judge Rosenthal remained unconvinced about Mazariegos’ progress, expressing skepticism about the sudden increase in his violent behavior. He remarked that Mazariegos’ record didn’t indicate such a drastic shift.

With concerns about Mazariegos possibly fleeing, Rosenthal set bail at $1,000 to ensure he would attend future court hearings.

Shortly after, Mazariegos was released on bail but was subsequently arrested for jumping on a car and smashing its windshield while making erratic statements. This incident marked his last arrest before allegedly killing Tanzi, and he now faces murder charges.

Efforts to reach his lawyer for comment were unsuccessful.
