As was evident with the recent trip to Luzerne County last week by Sean Lockhart and Grant Roy... attorneys for the Pennsylvania DA, as well as counsel for Harlow Cuadra and Joseph Kerekes are all most certainly in 'preparation mode' for the upcoming trial.
What is the preparation process you might ask... it's obtaining the materials needed during the course of the investigation including; discovery, depositions, medical records, and more:
"The problem of assimilating all of this information and preparing for trial is like carving a statue out of a block of solid granite. A famous artist once said, "The statue was always there - all I did was remove the excess granite. " But trial preparation is not so simple because the raw material may not be there and it may be necessary to take additional depositions, conduct further investigation or serve additional written discovery. For this reason, serious trial preparation should take place at least six months before trial."
Here's a great link that breaks-down the entire suggested process:

It should also be noted that this is a fairly generic process... it may not be the exact way the Bryan Kocis murder case is being handled. However, it will give you a good idea as to the things that are commonly done, and thus-far being followed-up by certain attorneys.
