A sentencing can take 4-8 months under normal conditions. I have judges in my district that order the US Probation/Parole Officer to write the pre sentence investigation an have a draft to the court within 120 days. In the 1st instance, the defendant gets 14-30 days to object, we get the same to respond. Those get incorporated into a final PSI and a sentencing date is set. Extensions are granted liberally in the first instance.
When you have a higher profile case, a more serious case or a case where someone may be cooperating, the above can take a bit longer and a strategy often applied is that the prosecutor does not want the sentencing hearing of the cooperator to happen until after those who they are cooperating against have pled and/or been found guilty.
In short, It could be 12-48 months before LAV is sentenced.
