(CNN) – Officer Matt Kenny of the Madison Police Department will not face charges in the March shooting death of biracial teen Tony Robinson, Dane County District Attorney Ismael Ozanne said Tuesday.
“I conclude that this tragic and unfortunate death was the result of a lawful use of deadly police force and that no charges should be brought against Officer Kenny in the death of Tony Robinson Jr.,” he said.
“My decision will not bring Tony Robinson Jr. back,” Ozanne told reporters. “My decision will not end the racial disparities that exist in the justice system, in our justice system. My decision is not based on emotion. Rather, this decision is based on the facts as they have been investigated and reported to me.”
Tony Robinson, 19, was fatally shot by a white officer on March 6 in Madison, setting off days of protests in the city. His death came amid lingering tensions over the killings by police elsewhere of other unarmed African-Americans that seized national attention.
The police department said in a statement Sunday that it has been preparing for Ozanne’s announcement for weeks, efforts that included holding meetings with community leaders.
“It is our hope — that working together — Madison can come through these challenging days ahead without violence or property damage,” it said.
Shooting at apartment
Police officials say that on the night of the shooting, Kenny was called to an apartment over reports that Robinson had been jumping in front of cars and assaulting people.
After hearing some commotion, Kenny forced his way into the apartment and was attacked by Robinson, according to police. Kenny responded by pulling out his gun and shooting Robinson, police officials say.
According to the Wisconsin State Journal, Robinson’s friends and family members have said he took hallucinogenic mushrooms and was behaving erratically the day he was killed. They reject the idea that Robinson was a threat to Kenny when he was shot, the newspaper reports.
Few details have been made publicly available about the confrontation between the two men.
The Dane County Medical Examiner’s Office said in a preliminary autopsy report that Robinson was shot in the head, torso and right arm.
Police say that Kenny suffered a blow to the head during the altercation. His attorney, Jim Palmer, said last week that Kenny was diagnosed with a concussion after the incident, according to the Wisconsin State Journal.
Previous incidents drew attention
Both Kenny and Robinson had incidents in their past that attracted attention after the shooting.
In 2007, Kenny shot and killed a man, Ronald Brandon, who was pointing a pellet gun at officers.
Kenny was exonerated of wrongdoing in that shooting and received a commendation.
Wisconsin Circuit Court documents indicate Robinson pleaded guilty in December to an armed robbery that occurred in April 2014.
Madison Police Chief Mike Koval and Madison Mayor Paul Sogin said in March that discussion of Robinson’s record was inappropriate.
“The fact that Tony was involved in any kind of transgression in the past has nothing to do with this present tragedy,” Soglin said.
