A woman who pushed a 74-year-old man off a Las Vegas bus in March 2019, causing his death, has pleaded guilty to an abuse charge. Cadesha Bishop, 28, was initially charged with murder and accused of pushing Serge Fournier off a parked bus near Fremont and 13th streets. Fournier landed on his head about 8 feet from the bus doorway, and died about a month later, according to Bishop’s arrest report.
