Washington, D.C. -

New information is emerging that faulty radios may have hampered the EMS response to Monday's Navy Yard shooting in Washington, D.C. 

An official with the U.S. Naval District of Washington Fire and EMS Department -- the department responsible for fire and EMS services at the Navy yard -- says the radios the Navy gave to the firefighters failed. 

"I would say there is a greater likelihood that more lives could have been saved," said Gregory Russell, fire inspector with the U.S. Naval District of Washington Fire and EMS Department.

He said a battalion chief who was first inside building 197 tried reporting details from the scene but couldn't because of the radio problems. 

"Immediately upon their arrival they were experiencing radio problems. They were not receiving and not able to transmit messages to other emergency responders," said Russell. 

WUSA reached out to Regional Fire Chief C.P. Miedzinski, who declined to comment by phone. 

Twelve people were killed in Monday's Navy Yard shooting.
