While mail fraud crimes often involve the use of the United States Postal Service, or USPS, you can also commit the crime when you use any interstate carrier, such as FedEx, UPS, or other delivery services. Mail fraud is super easy to prove [prints on box, cameras at fedex offices, credit cards used for materials, amazon accounts, logged ips, bank accounts involved, federal authority] and carries ridiculous sentencing: 20 years. THIS is a bad plan for $1500. Most likely this person DID THIS MORE THAN ONCE so they could face like 10 counts - it is 20 years per count. Not to mention people doing the investigation are federal officers - they are on point. With 2nd murder you at least get parole and probably wont do 20 years or charged with multiple counts. mail fraud = bad times.
