Demonstrations continued Monday over the death of an unarmed black man shot and killed by a Madison police officer Friday night, as protests in Wisconsin’s second-largest city stretched into a fourth day and reached the heart of the state’s government.

A large crowd gathered inside the rotunda of the state capitol, about a mile from the apartment where Anthony Robinson, 19, was shot after what authorities described as a struggle with a police officer.

Robinson’s death sparked outrage and drew national attention over the weekend, becoming the latest incident involving a black man dying at the hands of the police. Michael Koval, Madison’s police chief, said he understood how it seemed to fit the narrative that has spurred an ongoing conversation over race and policing, but he pleaded with people for patience while investigations are carried out.
