Who is burning the churches?

10 fires later, arson investigators still don't know who may be behind a series of church fires. Authorities do think they are dealing with a serial arsonist in East Texas, but catching the person or persons won't be easy. As officials will tell you, all the evidence gets burned up.

The series of fires has put churches on edge. I was told tonight that inside some small churches, armed security is ready and waiting just in case someone with a fire urge wants to stop by. There is a $25,000 reward and that could go a long way toward catching whoever is to blame. Let us hope the tips come in before another house of worship, burns.
