The son of a former Nevada State senator was murdered in a shooting at a Las Vegas-area casino before the alleged teen killer carjacked several drivers and led police on a chase through the streets of Sin City.

Na’Onche Osborne, 23, was mortally wounded inside a garage at the Aliante Casino & Hotel in North Las Vegas, 18 miles north of the famed Las Vegas Strip, early Thursday.

Osborne, the adopted son of former Democrat Senator Pat Spearman, died from multiple gunshot wounds, the Clark County Coroner’s Office announced Saturday, according to KTNV.

“It is with profound sadness that we share the news of the passing of Senator Spearman’s beloved son. This is an unimaginable loss for the Senator and their family, and they are heartbroken,” Spearman’s family said in a statement to the outlet.

“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.”

The suspected killer, identified as Aerion Warmsley, fled the resort before he crashed his car near Interstate 15 and Spring Mountain Road, close to Trump International Hotel Las Vegas.

The 19-year-old allegedly carjacked three vehicles on the roadway and led police on a chase around the city, reaching speeds up to 105 mph, the outlet reported.

During the chase, Warmsley crashed into a bus stop, critically injuring a mother of four.

He also allegedly struck at least one other pedestrian during the crash.

Warmsley was arrested and charged with felony murder with a deadly weapon and robbery, according to court records viewed by The Post.

He is being held at the North Las Vegas Community Correction Center, jail records show.

Police did not provide a motive behind the deadly shooting.

North Las Vegas Mayor Pamela Goynes-Brown gave her annual State of the City address at the Aliante hours after the murder.

Spearman was defeated by Goynes-Brown during the 2022 mayoral race despite being endorsed by former Vice President Kamala Harris.

The 70-year-old former politician says she adopted Osborne as a teen to “show him a better life.”

“I knew raising him would be a challenge because he was a child who had witnessed violence early in his life, and he would need a strong, loving and supportive home to grow up in,” Spearman said in 2022 after Osborne shot her nephew during a dispute inside the senator’s home.

Osborne shot and wounded his cousin after being confronted for blowing marijuana smoke into the face of a child, the Las Vegas Review-Journal reported.

The then-21-year-old was charged with attempted murder and battery in the shooting of his cousin.

He pleaded guilty to battery with a deadly weapon and carrying a concealed weapon, court records indicate.

Spearman says she was left “rattled to the core” by the shooting.

“Na’Onche made a very poor decision and he’ll have to face the consequences,” Spearman told reporters during the height of her failed mayoral campaign. “As a mother, I support the justice system and my son. It is with a heavy heart that my family is impacted by gun violence.”

Spearman was first elected to the state senate in 2012, successfully running for reelection twice before she reached her term limit in February.

In her final term, which began on Feb. 6, 2023, Spearman served as the president pro tempore of the legislative body.

She ran a failed campaign for a US Congress seat in 2020.

Spearman served 29 years in the Military Police Corps of the US Army, retiring in 2007 as a lieutenant colonel.
