When do the Statute of Limitations run out?
I believe 5 years applies here, but the crimes were alleged to still be in progress up until October, 2014, so the 5 years is measured from that time.
Bribery Statute of Limitations - Federal crimes are covered by 18 USC 3282, which states nobody may be tried, prosecuted, or face any punishment for any noncapital offense unless the indictment is found or information is instituted within five years of the commission of the offense.
Notice that it's "within five years of the commission of the offinse" and not ""within five years of the charge(s) being made."
I believe the crimes occurred as early as 2009 and continued until 2014.
