A 25-year old woman is accused of pushing an elderly man, who later died, off of a Las Vegas city bus. The family said that 74-year old Serge Fournier died from the injuries he suffered after the alleged assault.

Now surveillance footage has been released to the public.

Cadesha Bishop, 25, was arrested on May 6 and charged with open murder on an elderly-vulnerable person.

Police said Bishop was argumentative with people on the bus, and had gotten into a verbal spat with the victim before pushing him. A police report said Fournier had told Bishop to “to be nicer to passengers,” according to KSNV.

When officers arrived at the Downtown Las Vegas scene, Fournier refused medical attention, but he checked into a hospital later that night, police said.

Fournier’s family told police that he died from his injuries on April 23.
