I don't think anyone is surprised by this news.....hoping and praying for a reasonable explanation.
Excerpted: The San Gabriel Fire Department said the initial investigation showed no immediate sign of arson.
"We need to be diligent in our investigation and check all of the boxes," Negrete said. While arson investigations are routine with all fires at houses of worship, Negrete noted that this blaze came at a time of criticism of the California missions and damage to several statues of Franciscan Father Junipero Serra. This particular mission was founded by Serra in 1771 in San Gabriel, a few miles southeast of Pasadena. Church staff removed a statue of Serra from public view last week and put it in safe storage, Negrete said.
