Ammar Harris, 26, is the prime suspect in the shooting that resulted in a fiery crash and killed three people.
Metro Police said they suspect Ammar Harris shot and killed Kenneth Cherry Jr. from a black Range Rover on the Strip Thursday. Cherry's Maserati crashed into a taxi, killing the driver and a passenger.
The video, shot in a bathroom, shows Harris flashing a stack of $100 bills and talking about playing "the counting game."
The Las Vegas Police posted a version of the video online in the hope that it would help lead to Harris's capture.
Harris is considered the only suspect in the shooting, with investigators now saying they no longer consider Tineesha Howard, also known as Yenesis Alfonzo, a person of interest.
Howard's involvement has not only been ruled out, police said, but they accidentally distributed a photo of yet another woman, a reality TV star from Florida named Tasha Malek.
"THE REAL STORY ... MISTAKEN IDENTITY! I'M NOT INVOLVED," Malek tweeted.

Malek has retained a lawyer and has threatened to sue the police.
