According to law enforcement sources cited by The New York Post, Mazariegos became enraged after the victim held a subway gate door open for him at the Jay Street–MetroTech station.

The victim’s attempt at courtesy allegedly triggered the assault, which witnesses described as a prolonged and brutal beating that lasted more than ten minutes.

Mazariegos repeatedly punched the man in the face and stomped on his head multiple times, according to police.

He then stole the victim’s wallet before fleeing the scene on foot.

Emergency personnel transported the victim to New York-Presbyterian Hospital Brooklyn Methodist, where he was pronounced dead.

Police launched a citywide search and arrested Mazariegos later that evening in Times Square.

At the time of his arrest, he was carrying a samurai sword attached to his backpack, though the weapon was not drawn.

Officers took him into custody without incident and transferred him for questioning.

Investigators said Mazariegos has an extensive criminal history, including multiple prior arrests across New York City.

Law enforcement sources confirmed he was expected to be charged with murder in connection with the Brooklyn assault.

During his first court appearance Wednesday on unrelated charges, Mazariegos appeared to show no remorse.

As he was escorted from the courthouse, reporters captured him making incoherent remarks, including, “Why’d you take my planet?”

He also displayed what witnesses described as a partially toothless grin.

Sources told The New York Post that Mazariegos admitted to police that he attacked the 64-year-old man because he “didn’t like the way he looked at him.”

The motive, according to investigators, stemmed from the victim’s act of holding the subway door open—an action Mazariegos said he found disrespectful.

Police said surveillance footage and witness statements corroborate the timeline of events leading up to the attack.

The assault took place just outside the Jay Street–MetroTech station entrance during the afternoon rush hour, an area heavily trafficked by commuters and students from nearby universities.

The suspect’s criminal background includes arrests for assault, robbery, and weapons possession.

Authorities are reviewing his previous cases and pending charges to determine whether any could have prompted earlier incarceration or intervention.

Officials have not yet released the identity of the victim, pending notification of next of kin.

New York Police Department investigators have described the case as a random act of violence carried out without provocation.

The attack is one of several high-profile incidents in the city involving repeat offenders accused of violent crimes on or near the subway system.

The New York City Office of Chief Medical Examiner is conducting an autopsy to confirm the cause of death.

Prosecutors are expected to file formal murder charges later this week following the completion of the initial investigation and evidence review.
