I think I could help you with script 3. You want a radio message telling the robbers location... I assume you would want a grid reference (eg. FD17). I can't do that, but what I could do is have a marker be placed on the map that the robbers wouldn't see, marking their location. You could have a radio message accompany it.
"The robbers have been spotted! Check your map for their location."
Player checks map, sees they are near, say Lipany.
Would that work?
