CBS affiliate KLAS reports the incident happened at 13th and Fremont in Vegas. 

The woman was allegedly "yelling and cursing" at other passengers on the bus. That's when Serge Fournier, 74, told the woman to "be nice." Bishop then pushed Fournier off the bus, surveillance video showed.

Fournier suffered a bad fall and at first refused to go to the hospital, but he went later in the evening. Friends and neighbors told KLAS that even though he initially survived the fall, but he was left badly injured and remained in pain from a crushed hip until his death a few weeks later.

The Clark County Coroner later ruled his death a homicide.

The Las Vegas Metropolitan Police hopes to find other people seen in the video so they can serve as witnesses to the crime.
