A woman has been charged with murder after pushing a 74-year-old man off a bus and to his death.
The 25-year-old woman, Cadesha Bishop, was arrested after Las Vegas police released a video of the incident, and encouraging potential witnesses to come forward with any information they might have.
The man, Serge Fournier, initially survived the fall, but later died from injuries.
In the video, Ms Bishop can be seen speaking with Fournier after she entered the bus, and as he moved to get out of the vehicle with a metal cart.
As Fournier passes the suspect, she then pushes him from behind forcefully. He can be seen falling out of the bus and onto the sidewalk outside, landing on top of the metal cart he was carrying.
Fellow passengers and witnesses told the Las Vegas Review-Journal that Ms Bishop had been shouting profanities at other passengers before Fournier interceded and asked her to be nicer.
She then pushed him out of the bus, witnesses said. After the push, she then walked away without offering to help the senior citizen.
Trevor Taylor, a neighbour of Fournier’s, told local media: “He was an excellent neighbour. Very nice, religious person.”
He added: “No matter what his age, she should not have done that. People need a little more patience than what they have these days.”
