Sanford, FL Police Chief Bill Lee plans to resign

(CNN) -- Chief Bill Lee of the Sanford Police Department in Sanford, Florida, plans to resign, a city official familiar with the matter said Monday.

Lee's department was criticized for its handling of the investigation into the February 26 shooting death of Trayvon Martin, an unarmed teenager.

Lee said one month ago that he was stepping down temporarily, a day after the Sanford City Commission expressed no confidence in his leadership.
