Flores committed identity fraud. He or the fake id factory pulled the SS number out of the air. Let's say it was your SS number. When the SS deduction from his check was sent to SS, it is possible that it could accrue to your SS account, giving you more money when you enrolled in SS. But, more likely, SS recognized the problem and put that money in the Earnings Suspense File.
Identity Theft is assuming both the name and SS number of someone else. Often this is done to commit fraud, but it is works only if the name/SS stolen has a high credit rating and a substantial level of un-used credit.
Most prosecutors differentiate between identity theft to commit fraud and identity theft to work. When identity theft for work is committed, credit rating is un-important. They want a name and number that will pass the fedgov employee verification system. Identity fraud won't pass the employee verification system
There are identity theft rings operating in numerous US businesses that participate in the Employee Verification System. The ring bribes a clerk who works in the Human Resources dept who has access to ex-employee files and can easily find names/SS numbers that have previously passed the Employee Verification System
