Prominent young lawyer Robert Wone was “restrained, incapacitated, sexually assaulted, and stabbed” in a Dupont Circle home in Washington, D.C., in 2006, police said in an arrest affidavit released Friday that sheds new light on a high-profile homicide investigation.

The 13-page affidavit explores the lives of the three men living at the $1.2 million town house on Swann Street Northwest, their friendship, their romantic relationships — and their alleged meddling in a two-year investigation into the slaying of a promising lawyer.
