The injured barista, identified as Courtney Campbell, was transported to Harborview Medical Center and was listed in critical condition Thursday night.

KIRO 7 News video showed the charred espresso stand on Everett Mall Way and Fourth Avenue. People who were nearby also shot cell phone video and said they heard explosions leading up to and during the fire.

An Everett assistant fire marshal said the official cause of the fire is still under investigation.  As for the explosions sounds, he said it may be the cause of the fire, but could also be the tires of the car or aerosol cans popping in the heat.

The owner of the Shell gas station next to the stand said his cameras likely caught the beginning of the fire on camera, but he could not view the video until Friday morning because of power outage issues caused by the fire.

The fire reportedly happened around 5 p.m.
