LAS VEGAS (KLAS) — The man accused of shooting and killing the son of a former Nevada state senator threatened and asked a woman if she wanted to die the day before the deadly shooting at a North Las Vegas casino, NLVPD said in a video briefing Saturday night.
Aerion Warmsley, 19, faces charges of open murder with a deadly weapon and robbery with deadly weapon and is expected to face additional charges through the Las Vegas Metropolitan Police Department, police said.
On Wednesday, March 26, North Las Vegas police responded to a report of a domestic disturbance where Warmsley allegedly sent a woman a threatening text message asking her if she wanted to die, according to police.

When officers arrived they found Warmsley’s vehicle in the parking lot in front of the woman’s apartment. As officers attempted to speak to him, Warmsley drove away in a Mercedes sedan with “unique markings,” before officers could talk to him. Officers documented the encounter and forwarded the information to detectives.
The next morning on Thursday, March 27 around 4:30 a.m., North Las Vegas police received a call from security at the Aliante Casino and Hotel reporting that a man had been shot on the casino floor, police said.
When officers arrived, they found the victim, later identified by the Clark County Coroner’s office as Na’onche Osborne, 23, of North Las Vegas, deceased with gunshot wounds.
Police said preliminary information showed that Warmsley and another man left the scene in a Mercedes sedan with “unique markings” and stolen license plates. A short time later the vehicle was involved in a crash near Spring Mountain Road and Procyon Street near Valley View Boulevard in Las Vegas.
The two men ran from the crash scene and Warmsley then approached a nearby woman and stole her grey SUV Mercedes at gunpoint, police said.
Both of the men drove away in the SUV however the other man got out of the vehicle before police pursued it.
Over the span of several hours, Warmsley was involved in a series of “dangerous” crimes across multiple jurisdictions including additional car thefts, high-speed pursuits and reckless driving, police said.
With the help of its air unit, North Las Vegas police located and stopped Warmsley’s vehicle near Boulder Highway and Sahara Avenue where he was arrested and taken to the North Las Vegas Detention Center.
In 2022, Democratic State Sen. Pat Spearman identified Osborne as her son following his arrest for a shooting in her home.
In the 2022 incident, 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 pay restitution, records said.
“It is with profound sadness that we share the news of the passing of Senator Spearman’s beloved son,” a family spokesperson said in a statement to 8 News Now. “This is an unimaginable loss for the senator and their family, and they are heartbroken. During this difficult time, the senator and their family ask for privacy as they grieve and support one another. They are deeply grateful for the outpouring of love, prayers, and condolences from friends, colleagues, and the community.”
Spearman, who served several terms in the Legislature, lost a bid for mayor of North Las Vegas in 2022. Voters first elected her to the Nevada Senate in 2012. On Oct. 20, 2022, police arrested Osborne, then 21, after the shooting near Elkhorn Road and Decatur Boulevard.
