Las Vegas casino lacked security before ex-Nevada senator’s son shot, killed, lawsuit claims
LAS VEGAS (KLAS) — The family of a Nevada state senator’s son who was shot and killed inside a Las Vegas valley casino earlier this year is suing the property, claiming negligence.
Aerion Warmsley, 20, is accused of shooting and killing Na’onche Osborne, 23, inside the Aliante Casino and Hotel in North Las Vegas on March 27. In 2022, former Democratic State Sen. Pat Spearman identified Osborne as her adopted son following his arrest for a shooting in her home.

Surveillance video the 8 News Now Investigators first obtained showed the incident unfolding around 4:30 a.m. on the casino floor when Warmsley and another individual were recorded talking with Osborne, police said. The two then walked away, but Warmsley returned moments later and engaged in another conversation with Osborne.
Warmsley then pulled out a handgun and attempted to hit Osborne in the head, but missed, prosecutors said, citing the video. As Osborne tried to run, Warmsley fired, striking him in the head and causing him to fall.
Warmsley then fired six more rounds at Osborne before rummaging through his pockets and taking unknown items, police said. He then drove off in a stolen Mercedes, allegedly carjacking several people before leading police on a chase.
According to grand jury transcripts, Warmsley and another man spent the early morning hours of March 27 sitting in a stolen car in various locations at the casino. A security officer at the property interacted with the pair at least twice before Warmsley allegedly shot and killed Osborne.
Willecia Calhoun, identified in paperwork as Osborne’s natural mother, filed the lawsuit on Nov. 24. Calhoun identifies herself as the administrator of Osborne’s estate.
Calhoun and her attorneys claim casino staff “[failed] to manage, control, supervise, secure, and/or maintain the property in a reasonable and safe manner and/or failure to provide adequate and reasonable safety measures and/or adequate security personnel,” documents said.
The lawsuit cites claims of negligence, saying the property, among other things, failed “to provide adequate security for its patrons, invitees, and the public” and failed to “have [a] sufficient number of guards in visible areas as to deter crime.” They claim the shooting was “reasonably foreseeable.”
The lawsuit asks a judge to schedule a trial and for a jury to award damages in excess of $15,000, which is standard in Nevada civil cases.
Warmsley faces charges in both state and federal courts. There is no state statute in Nevada specifically regarding carjackings: the action of threatening a driver with a weapon and stealing their vehicle. Instead, state prosecutors will prosecute a person for grand larceny of a motor vehicle.

He was scheduled to appear in Clark County District Court on Dec. 2 for his attorneys, prosecutors and the judge to discuss the status of his case. A trial in his federal case was scheduled for January.
In 2022, Osborne shot his cousin, David Spearman, in Pat Spearman’s home, records said. A prior shooting at the home involving Osborne on Sept. 1, 2022, went unreported until the October incident, according to North Las Vegas police. A judge later sentenced Osborne to a year in county jail and to pay restitution, records said.
A representative for Boyd Gaming, which operates the Aliante property, previously said the company declines to comment on pending litigation.
