CLEVELAND: The brother of a woman killed in a hail of police gunfire after a high-speed chase has pleaded not guilty to disorderly conduct after allegedly making a death threat against the Cleveland officer standing trial in the shooting.

Thirty-five-year-old Alfredo Williams pleaded not guilty to the misdemeanor Wednesday.

A security guard reported hearing the threat outside the courtroom April 15 during a break in the manslaughter trial of 31-year-old Cleveland policeman Michael Brelo.

The security guard told the judge he heard Alfredo Williams say he would kill Brelo himself if he wasn’t convicted.

Prosecutors say Brelo was charged because he fired his last 15 rounds after suspects Timothy Russell and Alfredo Williams’ sister, Malissa Williams, were no longer a threat. His trial is expected to conclude this week.
