The family of Na’onche Osborne — the slain adopted son of former Democratic Nevada state senator Pat Spearman — has filed suit against the North Las Vegas casino where he was fatally shot earlier this year. The complaint, first reported by KLAS-TV/Las Vegas, targets the Aliante Casino and Hotel for negligence in its security practices.

Prosecutors say Osborne, 23, was killed on March 27 inside Aliante by 20‑year‑old Aerion Warmsley, who now faces murder and auto theft charges in both state and federal courts.

While Warmsley awaits his trials, Osborne’s biological mother seeks her own justice — claiming that the casino failed in its duty to protect its guests.

Willecia Calhoun, who identifies herself as the administrator of her son’s estate, claims Aliante did not provide “adequate security for its patrons, invitees, and the public” and lacked “a sufficient number of guards in visible areas as to deter crime.”

Her lawsuit asserts the shooting was “reasonably foreseeable” and seeks damages exceeding $15,000, the standard threshold in Nevada civil cases.

Grand jury records indicate Warmsley and another man spent hours in a stolen vehicle near the casino before the shooting, interacting twice with a security officer.

Despite those encounters, Osborne was later gunned down inside the property.

The civil suit requests a jury trial and asks the court to set a date. Meanwhile, Warmsley is scheduled for a December 2 status hearing in Clark County District Court, with his federal trial slated to begin in January.

Boyd Gaming, which operates Aliante, has declined to comment on the pending litigation.
