Eight fires burned in San Bernardino within about 10 blocks of each other in a 19-hour period, the worst of which left a vacant house in ruins, a fire official said.

They started with a small rash of four fires reported between 5:15 and 5:45 a.m. Tuesday, June 30. The biggest of those was a brush fire at Seventh and H streets. The other three were trash can fires in the surrounding area, said San Bernardino fire Capt. Mike Arvizo.

In the afternoon that day, three more fires were reported: in a grassy field, on a palm tree and another trash bin.

Then, at 12:26 a.m. Wednesday, July 1, a fire at a vacant house was reported in the 1000 block of North Stoddard Avenue, Arvizo said.

When firefighters arrived, they found the house fully ablaze. It took about two hours to extinguish, the captain said.

Firefighters managed to keep the fire from spreading to nearby homes, though a window of a nearby home did shatter because of the ambient heat, he said.

Neighbors reported that transients frequented the place, though whether they caused the fire in unknown.

The house fire is being investigated as suspicious, and the cause — along with the cause of all Tuesday’s fires — is unknown.

“We don’t know if they’re tied together,” Arvizo said.

Fire officials asked anybody with information to call the San Bernardino City Fire Department at 909-384-5777.
