How can you search DigitalFence for a specific MAC address?

The police have asked me to search for a specific phone MAC address within my Fingbox digital fence data if possible. A group with 2 stolen SUVs robbed our community a few days ago breaking into dozens of cars and garages across 5 blocks. DigitalFence provided 2 MAC addresses (at 4:32AM) out of 6 total devices (4 anonymized) that I was able to provide to police. They have asked me to add monitoring to another MAC because they expect the thieves to return. They stole a lot of garage openers from cars wherever they found them. 
1. How do I search for another specific MAC address to provide police? 
2. How can I add monitoring for this new MAC address (that has not ever been on my network)?
