A single rock was thrown at glass doors at each meetinghouse, said South Jordan police Officer B.J. Smith. Police have no suspects.
Typewritten notes attached to each rock with a black elastic hair-tie reading: "'Stop spreading your lies, pagans,'" Smith said.
The notes were printed on a single sheet of white paper, and the rocks were baseball-to-softball size. The double-paned, tempered glass was broken in only one of the churches. In the others, the rock broke through only the first pane of glass and landed outside the buildings.
They were thrown sometime after the last checks by church members at about 10:30 p.m. The incidents were reported between 6 a.m. and 7:30 a.m. Sunday, when members began arriving for early-morning church activities.
