One of the buildings is four stories in height. The initial call for help came slightly after midnight, officials said. \u2018An amazing effort\u2019 \u201cThe first guys on the scene made an amazing effort to get people out,\u201d Verdicchio said.

The block includes such businesses as Liquid Lunch and Howe Convenient on the first floor as well as offices and residences on upper floors.
