The family of slain podcaster Charlie Kirk has blamed officials at the university campus where he was killed for his death.
The Kirk family says the 31-year-old was put into a "fishbowl" courtyard without proper security before the attack by a rooftop sniper.
The wrongful death notice filed on the one year anniversary of the shooting is a precursor for a potential lawsuit.
Mr Kirk was shot dead by a rooftop sniper on September 10, 2025, while debating students in an outdoor courtyard.
A wrongful death notice now filed by his family has said "negligence" by Utah Valley University failed to protect the 31-year-old while on their campus.
The shooting happened during his largest campus tour, dubbed "The American Comeback Tour" by Mr Kirk's conservative organisation, Turning Point USA.
Mr Kirk had been debating students in the courtyard, which was surrounded by tall buildings "and other elevated observations".
An Associated Press review following the shooting showed the campus in Orem did not use several public safety practices that have become standard safeguards at events around the country.
The 23-year-old charged with shooting Mr Kirk dead has pleaded not guilty.
Ms Kirk has since been elected chief executive of Turning Point USA.
One year after the attack, bells tolled at 12.20pm local time at Utah Valley University, marking the time of Mr Kirk's death.
Outside Turning Point USA's Arizona headquarters, a 2.4-meter-tall statue of Mr Kirk was unveiled to mark the anniversary.
