He and other sanitation workers “went to work every day to make a difference in their communities,” the New York City mayor said.

A sanitation worker of 19 years died on job Saturday afternoon, city officials report. Richard Errico, 54, died when he fell and was run over by his own truck on Douglaston Parkway around 5:45 p.m., police say.

It was not clear on Sunday what caused Errico — who worked for the sanitation department for 19 years — to fall out of the truck.
