QUINCY, Mass. — Fire officials said a 2-month-old baby and a 1-year-old child are among the three people who died in an apartment house fire.

Deputy Chief Jeff Starr said the fire at a four-family home in Quincy, just south of Boston, was reported at about 3 a.m. today.

He said in addition to the three fatalities, one person was taken to Massachusetts General Hospital in Boston with serious burns.

Starr said he had no additional information on the victims. Another 15 to 20 people who lived in the building escaped.

There was no immediate word on the cause of the blaze, which apparently started in the basement.
