Sheriff Doug Gillespie made the disclosure Thursday about the early morning incident that left three people dead and at least six injured. Police withheld the names citing the ongoing investigation.
Police are seeking a black Range Rover Sport that fled the scene at Las Vegas Boulevard and Flamingo Road.
The intersection is home to famous casinos including Bellagio, Caesars Palace and Bally’s.
Authorities say at least one person in the Range Rover shot at a Maserati that then ran a red light and crashed into a taxi.
The taxi burst into flames, and the driver and passenger died. The driver of the Maserati also died, and his passenger was shot.
