Hundreds are expected to attend the funeral for an unarmed 19-year-old who was killed last weekend by a Madison police officer.

Tony Robinson, who is biracial, died March 6 after what police say was a confrontation in which he assaulted the white officer. A preliminary autopsy showed Robinson was shot in his head, torso and right arm.

Saturday's visitation and funeral will be held in a high school field house to accommodate a large crowd.

Robinson's death sparked several large protests in Wisconsin's capital city in the past week. An open letter signed by nearly 90 clergy members on Friday said Robinson's death exposed longstanding racial inequalities in Madison.

A state agency is investigating under a Wisconsin law that requires an outside agency to look into fatal police shootings.
