I utilized FirstTwo for a neighborhood canvas after a violent home invasion robbery. I used FirstTwo to compile a list of 39 residences directly around the victim residence. I obtained all the information before I drove to the residences from my desktop.
Once at the residence, if the occupant was not home I called the phone number(s) obtained from FirstTwo. After the canvas was complete, I noted only one phone number obtained from FirstTwo was disconnected. All other resident info as far as name and phone number was accurate. While this seems to be basic stuff it was a huge help and kept our Detectives organized.
FirstTwo is now my go-to product when I obtain a possible address for a victim/witness/suspect and need to confirm it.
