Lamar Alexander, R-Tenn., being escorted from his Washington home by U.S. Postal Inspector police. Loskarn has been found dead in Maryland, just weeks after the former staffer's arrest on child pornography charges. The Carroll County Sheriff's office said on its website Friday that Ryan Loskarn was found dead Thursday in Sykesville, Md. Deputies say the preliminary investigation shows Loskarn may have committed suicide. (AP Photo/WJLA-TV)
