He told her to be 'nicer' and she pushed him off a bus, authorities say. He died a month later

Las Vegas police on Tuesday released video of a woman pushing a 74-year-old man off a bus, asking witnesses to come forward and describe the alleged murder. 

The man hit his head on the sidewalk about 8 feet from the door of the parked bus, the Las Vegas Review-Journal reported, and died about a month later from his injuries. 

Witnesses told detectives that the woman, 25-year-old Cadesha Bishop, was yelling profanities on the Las Vegas bus in the late afternoon of March 21.

When Serge Fournier passed her in the aisle, the report reviewed by the Review-Journal said, he told her "to be nicer to the passengers." Then she pushed him off the bus with both hands, the video shows.

 

The muted surveillance video released by authorities shows a man holding a walker or folded cart. As he approaches the front of the crowded bus, a woman shoves him out the door with both hands. 

Bishop walked away without offering help, according to the report, and held her son's hand as they passed Fournier on the sidewalk.

Police said Fournier refused medical attention at the scene, the Review-Journal reported, but went to a hospital that night. He died from complications of blunt force torso injuries on April 23, leading the coroner to rule his death as a homicide. 

Court records show Bishop is charged with murdering an older person, the Review-Journal reported. She is scheduled to appear in court next week.
