SAN JOSE — A string of six fires that ignited within a two-mile area early Thursday morning are being investigated by the fire department as suspicious, including a blaze that damaged a convenience store.

All six fires were “outside” blazes and started in dumpsters or through a pile of debris, Torres said. One of the blazes jumped and damaged a business.

Four of the fires were all reported at about the same time, Torres said.

“Any time you have four simultaneous fires, it is suspicious,” Torres said. “They are all under investigation.”

On May 7 at about 1 a.m., video surveillance captured images of a person deliberately setting fire to a tool shed connected to the Assyrian Church of the East in Willow Glen. Officials with the church on Minnesota Avenue say they provided the footage to the San Jose Fire Department.

The fire burned a portion of the exterior of the church and was quickly extinguished, according to the fire department. Because the fire occurred at a place of worship, the U.S. Dept. of Bureau of Alcohol, Tobacco, Firearms and Explosives were also investigating, according to the San Jose Fire Department.

Torres did not immediately have an update on the investigation into the church fire, located about 1 mile away from the string of fires that ignited early Thursday.
