I don't know where to post this, but I do think it will get solved. I have been doing a 6 week course with Hernando County Sheriff's office. Last week we had our Forensic Dr. for out County speak and do demonstrations of how they get evidence and process it. Unlike CSI on TV, we do not have a fingerprint computer that runs though a database and comes up with a MATCH. No one does, just TV Shows. For every latent print, the computer comes back with a min. of 25 possible matches. So if you lift 50 prints, x 25 possible matches per print, that's 1,250 prints someone sits and looks at to see if it is a match. Yes they do print all the people in the family to rule out prints that belong in the house, but you still have to run them. Now think of all the people who could have come and gone in the house. You also have to think about the last time you really cleaned and got rid of prints in the process. I dust with a rug, but not always with Pledge polish. So if the cable guy was in my house, and his prints are on my TV they belong there, but I may have forgotten to tell LE. So the prints are run, and he isn't in the data base, because he doesn't have a record or has never been in the service. Someone has to run that down.
I ask how long for DNA to come back. Well we serve 5 counties, and some things are sent to the FBI labs. So if we aren't backed up with crime, and FBI are on schedule; maybe 3 months on average. Do they release it? Not till everything comes back and they are satisfied. So it's June and we wait, and they are working on it, just takes time. When they have what they need they will go to the SA and give them what they have, then he will decide if they have enough evidence to make a solid arrest and make it STICK. I hope that is what happens. But remember, lots of that evidence belongs in that MH. They lived there. If someone came in and wore gloves, that would be a reason they don't find prints that don't belong there. Now what? So it takes time. Every statement is read, reread, and listened to dozens of times, by lots of experts. They interviewed 300 people, and probably printed lots of them.
Have faith, it may be a year... or more... to put this together.
