Cosmo Silverman dies after being pinned between two SUVs while crossing his high school parking lot in Los Angeles

A heartbreaking accident has shaken a Los Angeles community after 15-year-old Cosmo Silverman was fatally struck in his high school parking lot.

The son of two well-known California artists had just finished his freshman year at Campbell Hall when the tragedy occurred, cutting short a life full of promise.

Cosmo was crossing through the school’s pickup line, a space meant for orderly departures, when a Rivian SUV pushed him into a Volvo, leaving him pinned and unable to escape.

The incident happened just as students were beginning their summer break, turning what should have been a moment of freedom into a family’s worst nightmare.

Parents File Wrongful Death Lawsuit

In response, Cosmo’s parents, Adam Silverman and Louise Bonnet, filed a wrongful death lawsuit in the Los Angeles County Superior Court.

The complaint alleges that Campbell Hall failed to comply with California law and neglected to protect their son.

“The Silvermans’ son was their pride, their hope, their purpose, and in an instant, Campbell Hall’s negligence shattered the life that embodied everything they cherished,” the filing reads.

Safety Hazards at Campbell Hall

The lawsuit highlights serious safety oversights at the private school, which charges $54,100 per year and counts A-list alumni like the Olson twins and Elle and Dakota Fanning among its graduates.

Cosmo had to navigate traffic without a proper crosswalk or safe path for students, leaving him exposed to moving vehicles.

According to California law, “vehicle traffic patterns must not interfere with foot traffic patterns,” a rule the complaint claims Campbell Hall repeatedly violated.

Changes Came Too Late

The Silverman family alleges that after the tragedy, the school hastily added safety features including a crosswalk, a stop sign, and fencing—changes that could have prevented the accident if implemented earlier.

The complaint states, “Only after Cosmo Silverman’s death did it take belated and elementary steps to remedy hazards that had long been apparent.”

Parents and community members had raised concerns about the parking lot for years.

One parent reportedly texted Adam Silverman after the incident, saying, “We have raised issues many times about the safety of the drop-off and pick-up, and the school is on notice and would not change things.”

Seeking Justice in Court

The Silvermans initially attempted to resolve the matter outside the courts, but the lawsuit now asks for a trial by jury after those efforts proved unsuccessful.

The family remains devastated by the loss of their son, whom Adam described as “the most beautiful boy in the world.”

Cosmo’s father reflected on the months since the tragedy, calling the time without his son “impossibly, crushingly sad.”

The lawsuit captures the emotional depth of their loss: “No parent should ever have to bury their child… the quiet now is unbearable: an empty chair at dinner, a phone that does not ring, a smile they still expect to see walking through the door.”

A Childhood Surrounded by Art

Cosmo grew up in a $2.5 million Los Angeles home with his parents, both accomplished artists—Adam working with textiles and Louise as a painter.

Their home, once filled with creativity and laughter, now serves as a painful reminder of the young life taken far too soon.

The community and family continue to grapple with the tragedy, hoping the lawsuit will hold the school accountable and prevent further accidents in school parking lots.
