NEWARK, N.J. — A Florida man who stole nearly $872,000 from companies in New Jersey, California and Nevada by submitting fake invoices for transportation services is now headed to prison.

Federal prosecutors in New Jersey say Karl Stehlin, also known as Mark Sawyer, received a 51-month sentence on Tuesday. He also will have to serve three years of supervised release and pay $837,618 in restitution.

The 61-year old Seminole, Florida resident had pleaded guilty in January to wire fraud.

Prosecutors say he created a bogus Idaho-based company and emailed invoices to get advance payment for transportation services that were never provided. The unidentified firms are factoring companies which purchase unpaid invoices from businesses to give them financial flexibility.
