Two St. Louis men face sentencing for planning a bomb attack targeting the Ferguson police chief and other officials after an officer killed Michael Brown there last year.

Olajuwon Davis and Brandon Orlando Baldwin pleaded guilty in June to felony counts of conspiring to use explosives and making false written statements while buying firearms. They are to be sentenced Thursday morning in St. Louis.

Their arrests during a sting investigation last November came days before St. Louis County Prosecuting Attorney Robert McCulloch announced that a grand jury wouldn't indict Ferguson officer Darren Wilson in the August 2014 death of 18-year-old Brown.

Davis and Baldwin admitted plotting to obtain explosives to use against McCulloch, then-Ferguson Police Chief Thomas Jackson and other officers.

None of the potential targets was injured.
