I woke up this morning feeling very sad and frustrated, not only by this case but a couple of others as well. I don't know why this case still has no suspect under arrest but I would like to explore the potential facts of murder investigations: How long does it typically take to process DNA? What might be the specific timetable in NC? What is the average length of time before a suspect is named in murder cases? How does that number differ between random and non-random murders, etc.? I don't know how much time I have to do this this morning but I wanted to throw these ideas out there so if anyone has any ideas or sources, maybe you could post them here.
