married artists Adam Silverman and Louise Bonnet<\/a>, who are the plaintiffs in the suit.<\/p>\n\u201cDuring his tragically short life, he left an indelible mark on his family, his friends, and everyone fortunate enough to know him,\u201d the suit reads. \u201cFor Adam and Louise, the death of their son was not just the loss of a life, it was the loss of every heartbeat that filled their home with joy, every dream they had watched take shape, and every fortunate moment they had counted on sharing.\u201d<\/p>\n
Officials with Campbell Hall did not immediately respond to requests for comment.<\/p>\n
Campbell Hall is a private Episcopal school whose notable alumni include Ashley and Mary-Kate Olsen; Dakota and Elle Fanning; and Jrue, Aaron and Justin Holiday. <\/p>\n
Cosmo\u2019s parents claim that students had to regularly walk through lines of moving traffic in the parking lot with no pedestrian paths, and that the school\u2019s protocol for school pickup violated state regulations. <\/p>\n

Security footage from June 4 captured the incident, as well as the Rivian SUV and a white SUV in the school parking lot before the crash.<\/p>\n

On the day of the incident, the Los Angeles Police Department received a call at 3:10 p.m. regarding a vehicle-on-pedestrian collision at the school, according to a department spokesperson. Cosmo was rushed to the hospital, where he was pronounced dead.<\/p>\n
Two additional minors and three adults received non-life-threatening injuries in the collision, according to the Los Angeles Fire Department.<\/p>\n
Since Cosmo\u2019s death, the school has changed how students are picked up, the suit says.<\/p>\n
\u201cBefore the incident, students routinely weaved through multiple lanes of traffic to access parked cars or to make their way to parents picking them up,\u201d the suit reads. \u201cCosmo was one of many students navigating his way through a line of intermittently accelerating and stopping vehicles when he was pinned and killed.\u201d<\/p>\n
The suit also alleges that parents raised concerns about the configuration of the school\u2019s parking lot during pickup times, and that school employees who were usually present to help direct traffic in the parking lot were not there on June 4.<\/p>\n
\u201cThere were no adults there to supervise the kids,\u201d Glassman said.<\/p>\n
Glassman said the decision to file a lawsuit came after Cosmo\u2019s parents were \u201cstonewalled\u201d by the school\u2019s insurance company, and they were unable to reach a resolution. <\/p>\n
\u201cThe lawsuit wasn\u2019t filed out of anger, but out of necessity,\u201d he said. <\/p>\n
Since then the school has made several changes, according to the suit, including a fence separating the pickup line from a nearby lawn, a foot pathway for pedestrians, and a stop sign in front of the pathway, among other changes. <\/p>\n
\u201cHad these basic safety measures been implemented before June 4, 2025, Cosmo and his classmates would not have been able to walk in between the vehicular traffic waiting in the pickup line at the end of school, and this tragedy would have been averted,\u201d the suit alleges. \u201cThe circumstances leading to this tragedy were entirely foreseeable.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Campbell Hall, the elite K-12 private school in Studio City, is being sued by two renowned artists after…\n","protected":false},"author":2,"featured_media":115708,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[61710,7906,61708,2624,48,52,51,1846,21023,47,50,49,7087,61709,61713,61712,61711,4265,4574,11469,821],"class_list":{"0":"post-115707","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-los-angeles","8":"tag-15-year-old-son","9":"tag-campbell-hall","10":"tag-cosmo-silverman","11":"tag-june","12":"tag-la","13":"tag-la-headlines","14":"tag-la-news","15":"tag-lawsuit","16":"tag-line","17":"tag-los-angeles","18":"tag-los-angeles-headlines","19":"tag-los-angeles-news","20":"tag-parent","21":"tag-parking-lot-crash","22":"tag-pedestrian-pathway","23":"tag-private-school","24":"tag-robert-glassman","25":"tag-school","26":"tag-student","27":"tag-suit","28":"tag-traffic"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/115707","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=115707"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/115707\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/115708"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=115707"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=115707"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=115707"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
