Firefighters in Oakland were trying to figure out what caused a suspicious one-alarm carport fire overnight, which was the second of its kind in two days.

Fire crews were called around 4:50 a.m. to reports of a car fire between a house and an apartment building at the intersection of Market and 41st streets, Oakland Fire Battalion Chief Emon Usher said.

Firefighters arrived on scene to find the carport fulyl engulfed in flames, which were spreading to a storage unit and a nearby home.

A few residents had already exited one of the buildings before firefighters arrived, and firefighters had to help residents living in the second floor of the apartment building exposed to the fire exit the building down a ladder, Usher said.

An arson investigator was on the scene trying to figure out if someone may have intentionally set the structure on fire.

No one was hurt but three vehicles and a storage unit behind the carport were damaged.

One family who had just moved into the house had their belongings, which were still in boxes, packed inside the storage unit. Sadly, the fire and smoke caused irreparable damage to their possessions. 

"I don't even know what to do. This is their first baby clothes," said Alejandra Sales, who had recently moved into the residence with her family, while holding a onesie damaged in the fire. "I put this on them when they were in the hospital for them to come home in and now it's all ruined. And that's all their toys that I bought last year. I worked really hard and now their toys are all gone."

The fire was the second in two days, leading investigators to believe that if Sunday’s fire was determined to be arson, it could signal that an arsonist was on a spree.

The first fire was at an apartment building on the 3300 block of Courtland Ave just before 4:30 a.m. Saturday.

When local fire crews arrived on scene, two vehicles in a carport were engulfed in flames.

It took firefighters about 15 minutes to bring the fire under control.

Investigators were quick to deem Saturday’s fire as suspicious but would not make the same determination on Sunday’s blaze, though investigators with the Oakland Police were called to the scene.
