SPRINGFIELD — A brave father died with his two young children when he rushed back into a burning apartment for them after first getting his pregnant wife and toddler out, while other residents dropped a baby to safety out a window, authorities and witnesses said.“He died for them,” Imam Wissam Abdul Baki of the Islamic Society of Western Massachusetts said of the Somalian father, who died with two of his young children on the second floor of a four-story, 20-unit brick residence at 49 Belmont Ave. in the early morning blaze yesterday.
