Are there sofrim in the DC area?Maybe they would remember an urgent request for tefillin during that time frame.It's too close to ny to be very hopeful, but it's definitely worth a try
My Uber account has receipts going back to 2013.
The straps look new. Together with this, I suspect it's someone who may not put on tefillin on a regular basis.
I could be that either, the straps got worn out, or, they might have been handed down/inherited, and the straps were replaced.
