The Miami Beach dispatcher, Damian Janee, took 14 minutes to send help to the 65-year-old man, and Miami Beach Fire Rescue took an additional 17minutes to arrive on the scene, The Miami Herald reported.
Deputy Chief Mark Overton of the Miami Beach Police Department, which manages the 911 center, said Janee should be fired.
"Most egregious is that he then went in and tried to alter the records ... to try to hide the mistake that he had made," said Overton.
According to union rules, Janee will go to a hearing before a final decision is made on his employment.
The reason is not yet clear for the fire rescue's delay in responding to a call for help two miles away from the nearest fire station.
The deceased man's widow said the fire rescue arrived with an EKG machine that didn't work and that rescue workers said their delay was caused by a raised bridge.
