Lord have mercy!
This is very tragic. I admit then when I read such stories I wonder why God does not immediately allow such desecrators to be struck dead, as a testament to his existence, power, authority, etc. Would not many come to faith reading that a man, in desecrating the altar of an Orthodox Church, is then found dead without any injuries or identifiable causes, within the parking lot of the desecrated church? Perhaps God in his mercy sees that even such a desecrator is not beyond hope, and may eventually come to repentance and salvation. We should at least hope and pray that this would be so.
