Suspect Named in Aliante Casino Homicide Case Following Series of Carjackings
In a dramatic turn of events in Las Vegas early on March 28, 2025, a high-speed car chase ensued following a fatal shooting at the Aliante Casino and Hotel in North Las Vegas. The suspect, identified as 19-year-old Aerion Warmsley, led police on a chaotic 20-mile chase that included multiple carjackings and culminated in his arrest.
The incident began at around 4:30 a.m., when Warmsley fatally shot Na’onche Osborne, 23, on the casino's gaming floor. Osborne was the adopted son of former Nevada State Senator Pat Spearman. Surveillance footage showed Warmsley confronting Osborne before violently attacking him with a pistol and shooting him.
Following the shooting, Warmsley carjacked a vehicle and led police on a high-speed chase that reached speeds exceeding 105 mph. The pursuit involved Warmsley exiting his vehicle in the drive-thru of a fast-food restaurant and committing a second carjacking.
Throughout the chase, Warmsley carjacked three vehicles in total. Using license plate readers, police were able to track the stolen vehicle from the carjacking to the downtown area. The police were assisted by a helicopter during the pursuit.
The chase ended around 9 a.m., when the police were able to ram the suspect's vehicle and arrest him. Bodycam footage captured the moment of his apprehension.
Warmsley is facing several serious charges, including open murder with a deadly weapon, robbery with a deadly weapon, and multiple counts of carjacking resulting in serious bodily injury. He is also facing federal charges such as brandishing a firearm during a crime of violence. Prosecutors are considering pursuing the death penalty against Warmsley.
The North Las Vegas Mayor, Pamela Goynes-Brown, delivered her 2025 State of the City address at the Aliante Casino, but did not address the homicide. Steve Grammas, president of the Las Vegas Protective Association, praised the police for their persistence in apprehending Warmsley.
