I am following this case very closely and one thing I have noticed that is common in all shootings is that the locations took place in areas surrounded by trees ( forest, hills with dense bush). The problem is that within a 50 mile radius of all shootings, most of the landscape has its locations of dense trees on hilltops, a prime location for a sniper to take cover.
This guy knows what he is doing. Just found out that an expert (geographic profiler) from Vancouver Canada has been hired by the Montgomery Police dept to determine where this individual lives. In a high profile case in Canada several years ago(Bernardo Trial), he pinpointed the murderer's residence within a 2 block radius, several days later they caught him.
This guy is a psycho that is for sure....
Hopefully he is caught soon
