Excerpts from ABC7Chicago.com:

Two people were killed in a house fire in the Back of the Yards neighborhood Wednesday morning. Firefighters responded at about 8:37 a.m. to a fire in a two-and-a-half-story home in the 2000-block of West 53rd Street.

A 16-year-old boy and 24-year-old were in the attic when firefighters said they became trapped and died. Authorities have not released their identities. Others in the house apparently tried to get to the victims.

The cause and origin of the fire is under investigation. CFD said there was not a smoke detector in the attic area.
