NBC 7 s Omari Fleming has the latest from the scene.
Based on the size of the building, the amount of fire damage and the injuries to the firefighters, the ATF was tapped last week by the Chula Vista Fire Department to help with the investigation into the fire’s origin and cause. The ATF – with 20 additional investigators – began processing the scene on Jan. 28.
Investigators determined the fire started on the second floor of Active Footwear. People were inside when it sparked at around 5:40 p.m. that day, but they all managed to escape safely.
The CVFD said high winds blowing through the county that day exacerbated the fire. As the flames spread quickly, the roof of the building collapsed.
It ll be unseasonably warm tomorrow ahead of a cold front that will move through the area on Thursday morning bringing back seasonal temperatures to end the workweek.
