Nice work by the Post’s David Nakamura over at D.C. Wire — he figured out that you can still call an old extension at the Office of Tax and Revenue and hear an outgoing message that begins, “You’ve reached the office of Harriette Walters.” Apparently officials decided to keep the line active with Walters’s voice message to see if anyone would leave a message for her that would aid investigators. We just gave it a call ourselves — 202.442.6762 — and indeed, there is Walters, sounding officious as she leaves instructions on how to reach her. Give it a call yourself if you’ve ever been curious what her voice sounds like, but do it fast. Odds are good the city is going to shut it down now that random residents are calling it for kicks.
