Jumping off this Zionsville aspect, sometimes if a killer is on a spree there will be another crime closely preceding another. Soooo, based on this location, etc, I think we should look at crime reports during that time near Zionsvillethat might not have stood out before, but that might stand out now. There might even be some stuff posted in the early threads because I as well as other posters usually look at this as one of the first things in a case, crime maps, etc... (for example, fires, vehicle thefts, etc.)
Wait a minute, fires....holy crap, what about the FIRE that killed the 4 girls? Have we discussed this yet in relation to DN? What would the distance be? It's Kokomo right, if I'm remembering correctly?
