The madman charged with randomly pummeling a beloved security guard to death<\/a> at a Brooklyn subway station\u00a0has been found mentally unfit to stand trial, a court heard Friday.<\/p>\n

David Mazariegos, 25, will be committed to a state psychiatric hospital after flunking a mental health exam \u2014 following the alleged merciless, unprovoked Oct. 7, 2025 killing of Nicola Tanzi, a 64-year-old security guard at MetroTech.<\/p>\n

Brooklyn Supreme Court Judge Dineen Riviezzo revealed that Mazariegos \u2014 a struggling artist with an escalating rap sheet before the attack<\/a> \u2014 had been \u201cfound unfit\u201d for trial before wishing the maniac good luck.<\/p>\n

\u201cWe will see you at some point at which you are better. Good luck with your treatment,\u201d the judge said during a brief hearing, just before Mazareigos was handed over to the custody of mental health professionals.<\/p>\n

Mazareigos, who appeared subdued and sleepy while wearing an orange prison outfit, will face first-degree murder and other charges if or when he\u2019s deemed mentally fit to stand trial at a later date.<\/p>\n

Prosecutors said Mazareigos punched Tanzi in the face at a security gate in the Jay Street-MetroTech station, near where the God-fearing Italian immigrant had worked for 15 years.<\/p>\n

Mazareigos then allegedly repeatedly stomped on Tanzi until his body went \u201ctotally limp\u201d \u2014 leaving him with a skull fracture, a crushed nasal bone and multiple other injuries to his face, prosecutors have said.<\/p>\n

Tanzi, a devout Catholic<\/a>, died a few hours later.<\/p>\n

The brute stole the victim\u2019s debit and credit cards to buy a samurai sword, which was found on him when police arrested him later in Times Squares, authorities have said.<\/p>\n

Mazareigos, who infamously shined a broken-tooth smile after his arraignment, confessed to beating the victim, robbing him and \u201ctaking his spirt,<\/a>\u201d according to prosecutors.<\/p>\n

His attorney, Zwi Wasserstein, declined to comment after Friday\u2019s hearing.<\/p>\n","protected":false},"excerpt":{"rendered":"The madman charged with randomly pummeling a beloved security guard to death at a Brooklyn subway station\u00a0has been…\n","protected":false},"author":2,"featured_media":95222,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[98,10916,303,2441,57,238,9,56,63,65,64,1687,58],"class_list":{"0":"post-95221","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-new-york-city","8":"tag-brooklyn","9":"tag-brooklyn-supreme-court","10":"tag-crime","11":"tag-mental-illness","12":"tag-metro","13":"tag-murders","14":"tag-new-york","15":"tag-ny","16":"tag-nyc","17":"tag-nyc-headlines","18":"tag-nyc-news","19":"tag-subways","20":"tag-us-news"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/95221","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/comments?post=95221"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/95221\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media\/95222"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media?parent=95221"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/categories?post=95221"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/tags?post=95221"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
