FERGUSON (AP) – An open letter to Attorney General Eric Holder from Ferguson merchants and residents is seeking resolution on a federal investigation into the shooting death of Michael Brown.

The letter states that the St. Louis County community won’t be able to move forward and rebuild until the investigation is complete and details of it are announced. The letter was announced Monday.

The Justice Department began its investigation in August, shortly after Brown was fatally shot by a Ferguson police officer, leading to protests and some violence.

A state grand jury’s decision not to indict officer Darren Wilson was announced Nov. 24. There is no timetable for completion of the Justice Department investigation.
