Police fatally shoot man in Madison, Wisconsin after officials say he produced a knife and injured an officer

A man was killed by Madison, Wisconsin police officers following a struggle in which officials say he produced a knife and wounded an officer. The incident triggered standard protocol responses: the involved officers were placed on administrative leave, and state authorities opened an investigation into the circumstances of the shooting.

Video recorded by a passing driver captured the moments leading up to the confrontation, the struggle with officers, and the sound of gunshots, according to CNN's reporting. The existence and content of that footage is expected to be a central element of the state investigation.

Officials stated the man was armed with a knife and that an officer was injured before the fatal shots were fired. No additional details about the condition of the injured officer or the identity of the man who was killed were included in available coverage.
