Not to be argumentative here, but there are statute of limitations on Felonies. It's only capital crimes that may be punished by the death penalty (like murder) that don't have a statute of limitations. That's the good news. The bad news is that more than likely, the Pharmacy will report it to LE (in accordance with procedure if it's a chain store) or the Dr's office will report it. Since this case is pretty easy to solve, they will probably do the investigation and either apprehend her or issue a warrant. Fact of the matter is, even if the Doctor or pharmacy don't press charges, the State Attorney will more than likely pick-up the charges and pursue them because 1: It's a felony and 2: It's drug related. Just my opinion from a Law Enforcement point of view, Good luck and I would definitely follow the advice above, have them retain an attorney and follow his advice and if necessary, ask for a deal from the judge in exchange for rehab or something.
