The mayor and fire officials said both firefighters had two children and asked for prayers for the families.
Among the businesses destroyed in the killer blaze was a dog grooming store that also boarded pets.
Regina Aries of Roslindale said she raced to the scene of the fatal blaze last night because she was worried about the dogs that were being kenneled there, but was much more horrified to learn that two Boston firefighters had been killed.
"It's just devastating," Aries said. "Devastating."
