MADISON, Wi. Activists protested for a third day in Madison, Wisconsin, on Sunday over the fatal shooting of an unarmed black teenager by a white policeman, the latest in a string of killings that have intensified concerns of racial bias in U.S. law enforcement. 
 
 More than 100 people angry over the death of Tony Robinson Jr. marched through the streets of Madison toward the capital building on Sunday evening, carrying signs, beating drums and chanting "The people united will never be defeated." 
 
 Earlier scores of people who took part in a sign-making event designed to involve children in the civil action rallied outside the apartment home where Robinson died. 
 
 Robinson, 19, was shot in Madison, Wisconsin's capital, on Friday evening after Officer Matt Kenny responded to calls about a man dodging cars in traffic who had allegedly battered another person, Police Chief Mike Koval said. 
 
 Kenny, 45, followed the suspect into an apartment, where the officer was struck in the head, according to Koval. Kenny then shot the unarmed teen, who died later in a local hospital. 
 
 Last year, the deaths of unarmed black men in Ferguson, Missouri, and New York City triggered a wave of demonstrations against the use of excessive force by law enforcement officers. 
 
 Kenny is on paid administrative leave while the Wisconsin Department of Justice conducts an investigation. 
 
 In a statement on the city's website, Madison Mayor Paul Soglin called the shooting "a tragedy beyond description" and said the city would be transparent in communicating results of an investigation into the shooting. 
 
 He noted that the incident occurred on the same weekend as the 50th anniversary of the "Bloody Sunday" march in Selma, Alabama, a turning-point in the U.S. civil rights movement. Kenny, a 12-year veteran of the Madison Police Department, was exonerated in a police shooting in 2007 and even earned a commendation in the incident, Koval said. 
 
 According to media reports, a 48-year-old man in that instance was shot to death after he pointed a gun at officers and refused to drop his weapon. The weapon was later determined to be a replica of a .38-caliber handgun. 
 
 Wisconsin court records show that Robinson pleaded guilty to armed robbery last year and received a probated six-month sentence. Koval declined to comment on Robinson's record.

There will be answers,” Madison Mayor Paul Soglin said in a statement Saturday. “When the answers come, we will be open and transparent in communicating them.” 
 
 Kenny, 45, had been involved in a previous officer-involved shooting, but was “exonerated of any criminal culpability” in that case, Koval said, saying the shooting was determined to be “suicide by cop.” Koval said Kenny later received commendation for his actions during the incident. 
 
 A Madison Police Department report said that a “man with a gun” at a residence was fatally shot by police in that July 15, 2007 incident. 
 
 The man who was killed, Ronald Brandon, called 911 to report a man with a gun threatening neighbors, gave a description of himself, and police said he pointed what looked like a firearm at them when they arrived, NBC affiliate WMTV reported at the time. The weapon turned out to be a pellet gun. 
 
 The Dane County District Attorney’s Office later cleared Kenny and two other officers involved in the shooting, saying that the victim pointed “a very realistic-looking facsimile firearm at police effectively compelled officers to resort to deadly force," the station reported. 
 
 When asked during Saturday’s news conference if Robinson had a record, Koval said it would be “wholly inappropriate” for him to discuss the character of someone who has “lost his life less than 24 hours ago.” 
 
 More than 100 protesters gathered at the scene of the shooting, according to witnesses and reports, with video showing the crowd chanting: “Who can you trust? Not the police.” 
 
 Some of Robinson's family members attended the protests, and said investigators have not allowed them to see his body. 
 
 "They won't let us come near him," Sharon Irwin, Robinson's grandmother, told the crowd that had gathered Friday night after the altercation. "I just want to hold him and tell him it's OK. Go home to God. They told me he was evidence." 
 
 “He was a beautiful, beautiful soul and everybody that knew him knew that,” Irwin told the crowd of protesters.
– Madison, Wis., saw peaceful protests yesterday in the wake of the shooting death of 19-year-old Tony Robinson by a police officer, with both Robinson's family and police urging non-violent demonstrations and the police chief vowing to "defend, facilitate, foster those First Amendment rights of assembly and freedom of speech." Robinson "was unarmed," says chief Mike Koval. "That's going to make this all the more complicated for the investigators, for the public to accept." The police response marks what the AP calls a "stark contrast" to Ferguson. "Our community has many questions, questions that I share. There will be answers," said Madison's mayor. "When the answers come, we will be open and transparent in communicating them." A 2014 state law mandates such cases be investigated by an outside agency, notes the AP. Officer Matt Kenny, a 12-year veteran who Koval said was injured in the struggle that ended in Robinson's death, has been placed on administrative leave pending investigation. He had been involved in a 2007 shooting death of a suspect, reports NBC; that case was later ruled to be "suicide by cop" and he was exonerated. As for Robinson's criminal history, "I'm not here to do a character workup on someone who lost his life less than 24 hours ago," said Koval. The AP, however, checked state records and found that Robinson pleaded guilty in October to felony armed robbery in connection with a home invasion; he was sentenced to three years' probation. A neighbor says she asked him about the robbery, which she deemed out of character. "He felt he was under a lot of pressure from the others to do what he did," she says. "He told me he would never do anything like that again."
