PHILADELPHIA (CBS) — A preliminary hearing for a 14-year-old girl charged in the tragic traffic cone beating death of an elderly man is now scheduled for next month. The preliminary hearing is set for Sept. 14.

Police say Gamara Mosley is one of the young people shown in surveillance footage hitting 73-year-old James Lambert with a traffic cone in June on Cecil B. Moore Avenue.

Mosley turned herself in to the police two weeks ago. She is charged with third-degree murder.
