Philadelphia Fire Department Commissioner Derrick Sawyer said his crews fought their hardest despite the quick-moving blaze that killed four small children.
The fire broke out Saturday morning in Southwest Philadelphia on the 6500 block of Gesner Street. The fire destroyed 8 rowhomes and displaced more than 40 people along with taking the lives of the four kids -- 4-year-old twin sisters Maria Bowah and Marialla Bowah, 1-month-old Taj Jacque and 4-year-old Patrick Sanyeah.
Sawyer spoke at a press conference on the scene following the fire along with Mayor Michael Nutter. Sawyer called the fire a "horrific tragedy on the street" and said that "hearts are heavy."
