Did you consider the police may already have a suspect? But, judges require probable cause to issue an arrest warrant (with exceptions). And, to convict, a prosecutor wants enough evidence to pursuade a jury beyond a reasonable doubt.
So, while Guest757 maybe an cyber sleuth, I would rather leave this to those who have been doing this for a while. Maybe they already (not literally) have someone in their grasp, but there are concerns this would go the way of Casey Anthony if an arrest was made at this point? CSI TV shows to the contrary, not all cases get solved in a neat one hour long package.
