A Baltimore judge on Monday cleared the highest-ranking cop tied to Freddie Gray’s death.

Lt. Brian Rice was found not guilty of involuntary manslaughter and reckless endangerment in a bench trial before Baltimore Circuit Court Judge Barry Williams.

Prosecutors had blamed Rice for Gray’s death because he did not put a seat belt on the prisoner when Gray was loaded into the back of a police van. Gray, 25, died from spinal cord injuries he suffered on his ride in custody.

Rice, 42, is the fourth officer to go on trial, with the previous three winning two full acquittals and one mistrial.

Two more cops go on trial, this month and in October, respectively. Gray’s death led to rioting that caused millions of dollars in damage and hundreds of arrests.
