The passenger who filmed and laughed while his friend ran over and killed a retired cop on a bike has been arrested in Clark County. The suspect, who is a minor, is expected to be tried as an adult. The incident was captured in a notorious video that circulated online, showing the murder of 64-year-old Andreas Probst. Prior to this incident, the two suspects were involved in a road rage incident and had hit another person on a bike. The driver is being prosecuted for hit-and-run and murder, and it remains to be seen if the passenger will face similar charges.
