The Santa Clara County District Attorney\u2019s Office has determined that two San Jose police officers lawfully shot and killed a man in a park who was charging at them with a knife.<\/p>\n
Mateusz Dzierbun, 48, of Fremont, had just stabbed his 9-year-old son to death last summer when he attacked the responding office, who shot and killed him.<\/p>\n
Just before he raised his knife and ran at the officers, Dzierbun told them: \u201cWhoever killed someone before needs to be here,\u201d and, \u201cIf you get the stun bag, I\u2019m going to get up and charge this guy.\u201d<\/p>\n
The officers \u2013 who had warned him numerous times to drop the knife so they could attend to his clearly badly injured child \u2013 shot Dzierbun 14 times.<\/p>\n
The report<\/a> says: \u201cThe officers were confronted with an extraordinarily dangerous and rapidly evolving situation. The evidence before them indicated only two possibilities: either Dzierbun had already murdered his son, demonstrating his homicidal intent, or the child had been stabbed by Dzierbun and required immediate lifesaving aid.\u201d<\/p>\n The District Attorney\u2019s Office investigates all fatal law enforcement encounters to determine if the lethal force was legal. By law, officers can use deadly force when they or others face imminent danger.<\/p>\n The fatal stabbing and subsequent police shooting happened in sunny Cataldi Park, near where a group of people were taking pickleball lessons.<\/p>\n On July 13, 2025, at approximately 3:23 p.m., Dzierbun called 911 to report that his son had been stabbed and \u201cis dead.\u201d At first, he said another man had killed him, and later admitted that he had killed his child, telling dispatch that, \u201cThey were going to torture him\u2026 I had to do it.\u201d<\/p>\n Officers Eduardo Eyer and Kevin McAlindon were the first officers to arrive at the park, at approximately 3:31 p.m. Dzierbun was approximately 50 feet away, seated on the grass near the body of his child.<\/p>\n An officer said, \u201cSir, will you please drop the knife?\u201d Dzierbun responded, \u201cListen to me very carefully. I am armed, and one of you guys is going to kill me today. I don\u2019t want to traumatize you.\u201d\u00a0 The officer repeated for a third time, \u201cSir, I need you to drop the knife,\u201d to which Dzierbun responded, \u201cI don\u2019t want to traumatize anyone here\u2026so listen to me carefully. Whoever killed someone before needs to be here.\u201d<\/p>\n Eventually, Officer McAlindon went to get a stun gun. Approximately two minutes after the officers arrived on scene, joined shortly after by Sergeant Joel Casey, Dzierbun stood up, brandished the knife by raising it above his head, and charged at them, body worn camera footage show<\/a>s.<\/p>\n Sgt. Casey and Officer Eyer fired.<\/p>\n Officer Eyer later told investigators, \u201cI need to save myself and my partners here\u2026 I wanted to save that kid.\u201d\u00a0 When officers managed to get to the child, they quickly realized he was deceased.<\/p>\n \u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"The Santa Clara County District Attorney\u2019s Office has determined that two San Jose police officers lawfully shot and…\n","protected":false},"author":2,"featured_media":8424,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[29],"tags":[8407,8528,88,90,89,52239],"class_list":["post-409155","post","type-post","status-publish","format-standard","has-post-thumbnail","category-san-jose","tag-district-attorney-jeff-rosen","tag-fatal-shooting","tag-san-jose","tag-san-jose-headlines","tag-san-jose-news","tag-santa-clara-county-district-attorneys-office"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/409155","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=409155"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/409155\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/8424"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=409155"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=409155"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=409155"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
