From what I could glean from the redacted police reports it appears that RR's cell number was gotten in the following manner:
LE went to MD (and RR) residence of record. There was nobody home and there appeared to be a realtor's lock on the door. LE then took note of the vehicles parked at the residence (one belonging to MD and the other belonging to RR) and ran the plates etc.
Then LE went to the leasing office for the community the residence was located in and spoke with the leasing agent/landlord. The police report then states witness, ___________ provided me with ____________'s phone number.
I am thinking the landlord gave LE the number.
Isn't it funny how something that seems relatively inconsequential can get stuck in your brain and not let you rest til you resolve it?
Page 39 of police reports talks about the cell phone call etc
