From the Daily News:
A suspicious two-alarm fire ripped through an illegally converted Bronx building early Wednesday, leaving a young mother and her 2-year-old son in critical condition.
Flames raced through the two-story West Farms home - which was carved up into a warren of tiny apartments - and trapped the mother and son in the basement at 6:15 a.m., officials said.
Fire marshals have not pinpointed the cause of the blaze but suspect an incendiary was used, FDNY sources said.
Investigators are also talking to witnesses who claimed the occupant of the basement apartment was fighting with another woman in the hours before the blaze.
The two-story building was zoned to house two families, according to the Department of Buildings' website.
Sources said several more apartments had been illegally added but it was unclear how many because of the extensive damage.
In 2006, building inspectors issued a violation because 13 apartments were found inside the home, according to records.
Since then, six more complaints - all for reports of illegal occupancy - were lodged against the owner. It was not clear if they were resolved.
