The woman, Sondra Arquiett, who then went by the name Sondra Prince, first learned her identity had been commandeered in 2010 when a friend asked about the pictures she was posting on her Facebook page. There she was, for anyone with an account to see — posing on the hood of a BMW, legs spread, or, in another, wearing only skimpy attire. She was surprised; she hadn’t even set up a Facebook page.

The account was actually set up by U.S. Drug Enforcement Administration special agent Timothy Sinnigen.

Not long before, law enforcement officers had arrested Arquiett, alleging she was part of a drug ring. A judge, weighing evidence that the single mom was a bit player who accepted responsibility, ultimately sentenced Arquiett to probation. But while she was awaiting trial, Sinnigen created the fake Facebook page using Arquiett’s real name, posted photos from her seized cell phone, and communicated with at least one wanted fugitive — all without her knowledge.
