A former Fulton County jailer pleaded guilty today to lying about the death of a mentally ill inmate. Derontay Anton Langford, 33, admitted lying to a federal grand jury investigating the March 2008 death of inmate Richard Glasco (left). Former detention officer Curtis Jerome Brown Jr., accused of the beating that led to Glasco’s death, and another former deputy are scheduled to go on trial next month. Langford faces a penalty of up to 10 years in prison. Look for Langford to be a witness if it goes to trial.
