Maricopa County (Ariz.) Attorney Bill Montgomery said Wednesday there will be no criminal charges against a Phoenix police officer who fatally shot unarmed suspect Rumain Brisbon in December.

The seven-year police veteran with a seemingly unblemished record shot and killed Brisbon outside of an apartment near Greenway Road and Interstate 17 on Dec. 2, AZCentral reports.

Brisbon's death triggered a series of downtown demonstrations, with protesters denouncing the use of force as excessive and racially motivated. Brisbon is Black, the officer is White.
