My guess is 2 or 3 deaths that day. Okay, according to the 2016 Arizona Crash Facts Summary [0], there were 952 fatalities on the road that year, including 193 pedestrian fatalities and 31 pedalcyclist fatalities.
So, on any given day in 2016, there were 2.6 fatalities, with less than 1 in the pedestrian/pedalcyclist groups.
