"Brown and Street were charged with nine counts of felony larceny (for the recovered motorcycles) and 10 counts of felony possession of stolen property" Is a felony state or federal?
If they find evidence of the bikes being moved over state lines or out of the country, then the feds might pick it up and charge them on the federal level. These are felony charges. Generaly speaking, misdemeanors are crimes that have a max sentence of a year. Everything else would be a felony.
