Video showing a woman violently pushing a 74-year-old man out the door of a stopped bus in downtown Las Vegas on March 21 was released by the Las Vegas Metropolitan Police Department on Tuesday.
Serge Fournier initially survived the fall but later died of his injuries at a hospital on April 21.
The woman, identified by police as Cadesha Bishop, 25, now faces murder charges, police say.
In the video, a suspect is seen pushing Fournier with both hands down the front steps of the bus. Fournier, holding his walker, falls flat on his face, hitting his head on the sidewalk.
Bishop, who was reportedly yelling and swearing at others on the bus, allegedly pushed Fournier after he asked her to be nicer to other passengers.
