Don't be too quick to dismiss these identity anomalies.  These might be clues to something else- Synthetic Identity Fraud.  https://www.trulioo.com/blog/synthetic-identity-fraud/   ...The concept is to create fake identities usually based on combining fake information with actual ID data. One example of what comprises a fake identity is one that contains a real social security number along with a fake address and other synthetic data points. The fraudster can then use the fake identity to acquire driver’s licenses, passports and other real ID as well as credit cards and other accounts...      I'm not suggesting that is what we are seeing in this case.  But I am saying that we cannot simply dismiss identity facts that seem out of place, or a bit too unusual.
