My friend used someone's credit card a and spent 1000 dollars. How much jail time is she facing?

Most likely probation if this is his first time

Depends on where this is, Also have they already repaid this person for all costs, including any interest on card for these charges.

Most likely probation, but depending on area, they can get 1 to 3 years in jail ( prison) for this, if the judge gave them max
