Sonny Thiera is finally back in his Mission Bay home after the fire across the street forced him to evacuate.
"It's still hard to fathom how this took place seems like we're living in a dream world," he said.
René Garcia describes the burned-out rubble of what used to be a luxury apartment complex under construction until a massive fire destroyed it on Tuesday.
"Devastating shocking, it really is apocalyptic," Garcia said.
Firefighters are still putting out hotspots and arson investigators are searching for a cause. ABC7 News has learned they're focusing on the northeast corner of the building at 4th and Mission Rock streets. Atop a ladder truck is the closest they can get because it's too dangerous to go inside.
"You can see where the fire had major growth or origin; they might have been able to see what they need to see," San Francisco Fire Deputy Chief Mark Gonzales said.
Fire officials say construction workers were using welding torches on site before the blaze began, but still can't say if that was a factor.
Meanwhile, the construction firm building the ill-fated structure took out a full-page ad in the San Francisco Chronicle thanking firefighters and police for their rapid response.
