Address for Phillip Mathew Morrow last known address is 8824 Kelsey Dr Elk Grove, Ca?

Usually when someone moves they have their mail forwarded to their new address. You could try sending a note to the last known address and requesting the new address in return. If it has been a very long time since that was their address though, it's likely the current resident will receive the note instead. No harm in trying though. Good luck. :)
