WASHINGTON — An internal investigation shows five District of Columbia firefighters were aware that a man had collapsed and needed medical attention across the street from a fire station, but none of them went to help.

The report was issued Friday by the city's deputy mayor for public safety. It says one firefighter already is facing internal charges, and charges are pending against three others. A probationary firefighter also faces discipline.

The report also recommends discipline for four employees at the city's 911 call center for their roles in sending an ambulance to the wrong address.

Medric Cecil Mills went into cardiac arrest in a shopping center parking lot across from a fire station on Jan. 25. The 77-year-old longtime city employee later died at a hospital.
