The 2009 Pulitzer Prize for Public Service has been:
“Awarded to the Las Vegas Sun, and notably the courageous reporting by Alexandra Berzon, for the exposure of the high death rate among construction workers on the Las Vegas Strip amid lax enforcement of regulations, leading to changes in policy and improved safety conditions.”
Unsafe working conditions on the Las Vegas construction sites resulted in 12 fatalities in 18 months.
