Police in the U.S. state of OH fatally shot a Black teenager who appeared to be lunging at another person with a knife, less than an hour before former officer Derek Chauvin was convicted of murdering George Floyd.

One police officer on the scene was wearing a "blue lives matter" face mask, Graham said, which he considered insensitive. "We know we can't provide every answer, but it's important that we can answer some questions tonight".
The police shooting in his neighborhood "just brings it home a little closer", he said, and reaffirms his decision to tell his 18-year-old son - who, like Graham, is Black - never to call the police. Police confirmed the person died at the hospital.
"I say you never call the police for anything, you call your daddy", Graham said.
The police chief said the video, which he said shows the slain teenager trying to stab both females, was released to the public within hours of the incident in the interest of "transparency".
