James Edgar Lewis, 64, was fatally shot while sleeping under a bridge in Las Vegas on February 2, 2018. Surveillance footage shows a dark-colored Hyundai Tucson pull up near where Lewis slept; a man exits, shoots him, then returns to the vehicle and drives away. Las Vegas Police and the coroner say Lewis was the fourth and final victim in a series of random shootings that targeted homeless people and others over several days, with the attacks beginning January 29, 2018. Authorities reported the same gun was used in all four shootings and described the suspect as driving a Hyundai Tucson.

The investigation identified 26-year-old Joshua Castellon of Las Vegas as a suspect, and he was facing murder and attempted murder charges. Lewis’s daughter, Oneida Lewis Baker, spoke of her grief and outrage and said the killer doesn’t deserve freedom. The case drew attention to the particular vulnerability of homeless people in the city.

Did anyone who knew James Lewis or who was near the bridge that night see or hear anything that could help explain what happened?
