This "Penrod" is a Nimrod. Can be interpreted as socially inadequate.
Unrecognized number, did not answer. Google brings this number up as belonging to "Jeffrey Penrod" in Mesa, AZ. A search on that name reveals a Private Investigator of the same name, based in Mesa, running a business called "Quantum Investigations". Unknown if same person or if number is being spoofed.
When i go to call this number back it says call cannot be completed as dialed.
