Two Indianapolis officers, who fatally shot an unarmed black man in June, will not face criminal charges, a special prosecutor has ruled.

Prosecutor Kenneth Cotter issued a statement Tuesday, saying officers Michal Dinnsen and Carlton Howard had to shoot 45-year-old Aaron Bailey out of fear for their own safety.

The officers believed that Bailey, who fled a traffic stop before being killed on June 29, was reaching for a gun, Cotter said.

There was “insufficient evidence to refute” their claims “of subjective fear or the objective reasonableness of that fear,” Cotter wrote in his statement.

“This decision was not taken lightly and was made after extensively reviewing the investigatory materials, re-interviewing witnesses and assigning an investigator within [Cotter’s] office to conduct a supplemental investigation,” Cotter’s office said in the statement.
