The biological mother of a man killed in a March shooting has filed a lawsuit against the North Las Vegas casino where the killing took place.
Willecia Calhoun, identified in the lawsuit as Na’Onche Osborne’s natural mother, filed a lawsuit Nov. 24 alleging Aliante Casino operators “failed to provide adequate security” before the March 27 shooting death.
Authorities have said Aerion Warmsley, 19, killed Osborne, 23, in the March shooting, which took place on the Aliante casino floor, then fled from police in a high-speed chase, stole three different cars and hit two pedestrians as he tried to escape.
Osborne, of North Las Vegas, was the adopted son of Pat Spearman, a former North Las Vegas state senator and mayoral candidate.
In the 14-page complaint, filed in Clark County District Court, Calhoun alleges casino operators failed to “manage, control, monitor, secure and/or maintain” the casino or provide “adequate and reasonable security measures and/or adequate security personnel.”
The complaint alleges that Aliante Casino, owned by Las Vegas-based Boyd Gaming Corporation, is also located in a “high crime area” and that additional measures to protect casino patrons should have been in place. Aliante is located just north of the 215 Beltway and North Aliante Parkway in North Las Vegas.
Those measures, according to the complaint, should have included an “adequate number” of security guards in visible areas to “deter crime,” more security cameras and metal detectors “to prevent people from bringing firearms into the casino.”
It also said there was no failure to provide “adequate lighting” in and around the property. The shooting, according to police, occurred at 4:30 a.m. on March 27.
Calhoun is seeking monetary damages, according to the complaint, in excess of $15,000. Because of Osborne’s death, according to the complaint, she has suffered intense “physical and mental pain, shock and agony.”
In an email, Boyd Gaming spokesman David Strow said the company does not comment on pending litigation.
In June, Warmsley was charged with murder with the use of a deadly weapon, robbery, reckless driving resulting in substantial bodily harm and duty to remain at the scene of a crash involving death or personal injury. He also faces federal gun and carjacking charges.
Assistant Clark County Prosecutor Morgan Lombardo said in June that prosecutors were considering the death penalty for Warmsley.
Osborne died of multiple gunshot wounds, the Clark County medical examiner said after the shooting. Spearman served as a Democratic state senator for Nevada Senate District 1, which includes part of North Las Vegas, from 2013 to 2025.
