I've been brewing up an idea that I believe would be awesome. and I think I may have mentioned this under my old screen name sleepysunshine

A serial cult killing (think Charles Manson and Helter Skelter) but the bodies would be dumped in an abandoned FBI building, and the authorities haven't noticed anything because the building is condemned. The body count near 100, one for each solstice.

Yeah, we have an abandoned FBI building in Charleston, and every time I pass by there, all I can think about is that would be an awesome body hiding spot
