Chief Mike O'Neil told the newspaper that his death has been difficult for his co-workers.
"To respond to an emergency on one of their own, a co-worker, and do the job that they did is pretty amazing, and it is well above and beyond the call of duty for the folks who were working that night.
"He was a well-respected public servant. He had immense pride in his occupation; he has immense pride in his family, as well. You couldn’t find a better person to deal with."
Funeral arrangements are still pending.
