WESTBROOK — Authorities have identified the man who was killed in an early morning fire today as Gerald A. Demers, 63, of Westbrook.

Firefighters were called to 9 Tramway Lane at 4 a.m. The small apartment building is located near the Main Street fire station.

When firefighters arrived they found a man engulfed in flames, said Michael Pardue, the city’s public safety chief. The man, who relies on an oxygen tank to help him breathe, had apparently gone out on the porch to smoke, Pardue said.

Family members had discovered him and were able to turn off the oxygen canister to prevent a more serious tragedy, Pardue said. The fire did not spread to the building.
