Ten minutes later, the incident was escalated to a second alarm, which means additional units were dispatched after the initial call for service.

At 1:51pm, a post on the department's Twitter feed indicated that the fire has been contained, with subsequent updates reporting that three people suffered life-threatening injuries. The cause of the fire is unclear, and it's unknown whether any residents were displaced.
