His high priced lawyer will get him a short sentence of 1 or 2 years.
The monthly court appearances kept getting postponed because the lawyers were looking for any holes in how the Police and Forensic staff handled everything. When nothing was found to get him off they then started the back room negotiations.
If the judge gives him anything less than 5 years then shame on our court system.
This is all just speculation on my part, so don't take it as gospel.
