1 dead in Northwest Side fire

One person is dead and six people were displaced after a house fire broke out Tuesday in North Mayfair on the Northwest Side.

Firefighters responded to a call of a fire at 12:28 a.m. in the basement of a two-story, single-family house in the 4800 block of North Keystone Avenue, Chicago police and fire officials said.

Antonio Zepeda, 39, was pronounced dead on the scene, the Cook County medical examiner’s office said. An autopsy Tuesday did not rule on the cause and manner of his death pending further investigation.

Another male refused medical attention, authorities said. No other injuries have been reported at this time, but six people who were upstairs and able to escape were displaced.

The cause of the fire is under investigation, but preliminary reports suggest the fire was accidental, officials said.
