Vandals who ransacked an LDS Church building in the Spokane Valley over the weekend scrawled Satanic messages during their rampage, deputy sheriffs said.

Damage to the building was estimated at $11,000, Lt. Norm Nickerson said.The word "Satan" was scratched into a piano, and the message "Lord Satan, there is no other" was written in chalk on a door, Nickerson said.

He said the vandalism apparently occurred between late Friday night and early Saturday when a church member discovered it.

Inside the church and offices, glass, computers and other items were smashed. Oil was spread throughout the building, and the contents of a fire extinguisher were sprayed inside.

Nickerson said it seemed to be vandalism by juveniles, not a cult.
