Now this comes with a big "Not a Lawyer" Disclaimer, but he's looking at one Felony 1 charge and three Misdemeanor 1 charges. M1s in Penn are a maximum of 5 years, and F1s are minimum of 10. Now this means Sick Nick is looking at anywhere between 10-25 years at minimum in prison assuming all the charges stick with him by the time he gets to sentencing, all depending on how Pennsylvania adds it up in the end (concurrent vs consecutive, how many years he gets on the M1s, etc etc). And again not a lawyer, so no idea what the maximum he could face is, the math appears much less clear cut on that.
Rip in Peace asshole.
