A man found murdered outside a swanky Long island yacht club was stabbed to death<\/a> in an ambush attack by his ex-girlfriend\u2019s new beau as his former lover egged him on,\u00a0prosecutors said Thursday.<\/p>\n

Delivery driver Kacy Corso, 33, and new boyfriend Victor Panebianco confronted Christopher Millwater in a parking lot near Stony Brook Yacht Club on Nov. 10 \u2014 with Panebianco demanding the victim say he and Corso were through as she told the killer \u201cdon\u2019t believe him, don\u2019t let him fool you,\u201d the Suffolk County District Attorney\u2019s office said.<\/p>\n

The crazed couple had allegedly rammed Millwater\u2019s car and blocked the exit to trap him inside the parking lot, where local\u00a0boaters and club members like Millwater were known to park, officials said.<\/p>\n

The deadly attack came after Corso slammed Millwater, 52, in a series of nutty social media posts where she warned him about contacting her and called him a \u201cgrave robber.\u201d<\/p>\n

Prosecutors said on the night of the attack Corso plowed into Millwater\u2019s vehicle, disabling it before a knife-wielding Panebianco\u00a0chased after him on foot \u2014 then pinned him down on the ground, prosecutors said.<\/p>\n

The new boyfriend then asked Millwater about his past relationship with Corso before stabbing him multiple\u00a0times in the heart and lungs, prosecutors said.<\/p>\n

The pair fled to North Carolina following the attack, but Corso was picked up by authorities when she returned to Long island Wednesday, prosecutors said.<\/p>\n

Millwater, of Selden, was found gravely injured around 3:40 a.m. and was taken to Stony Brook University Hospital, where he was pronounced dead, police said.<\/p>\n

Corso apparently unleashed on Millwater and issued a chilling warning in a July 26 Facebook post.<\/p>\n

\u201cAs you can see\u2026 psycho much?? If anyone knows him better talk some sense into him before it\u2019s too late.\u201d<\/p>\n

Corso included screenshots that showed purported messages between her and Millwater.<\/p>\n

She also posted a screenshot of another social media user criticizing Millwater.<\/p>\n

The murder shook the usually quiet North Shore suburb with one resident previously telling News 12, \u201cThat usually doesn\u2019t happen here.\u201d<\/p>\n

Millwater actively posted on Facebook, including one eerie online remark.<\/p>\n

\u201cPlenty of time to rest when I\u2019m dead so now it\u2019s a quick shower and gym time,\u201d he wrote two days before he was killed.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"A man found murdered outside a swanky Long island yacht club was stabbed to death in an ambush…\n","protected":false},"author":2,"featured_media":46360,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[776,57,238,9,11,10,773],"class_list":{"0":"post-46359","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-new-york","8":"tag-long-island","9":"tag-metro","10":"tag-murders","11":"tag-new-york","12":"tag-new-york-headlines","13":"tag-new-york-news","14":"tag-suffolk-county"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/46359","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=46359"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/46359\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media\/46360"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media?parent=46359"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/categories?post=46359"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/tags?post=46359"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
