Arrest follows fatal shooting of two amid protests over police shooting in Kenosha, Wis.

Kenosha, Wis. — A white, 17-year-old police admirer was arrested Wednesday after two people were shot to death during a third straight night of protests in Kenosha over the police shooting of a Black man, Jacob Blake.

Kyle Rittenhouse of Antioch, Ill., about 15 miles from Kenosha, was taken into custody in Illinois on suspicion of first-degree intentional homicide in the attack Tuesday that was largely captured on cellphone video. The shooting left a third person wounded.

“I just killed somebody,” the gunman, carrying a semi-automatic rifle, could be heard saying at one point during the rampage that erupted just before midnight in the city of 100,000 people midway between Milwaukee and Chicago.

In the wake of the killings, Wisconsin Gov. Tony Evers authorized the deployment of 500 members of the

National Guard to Kenosha, doubling the number of troops. The governor’s office said he is working with other states to bring in additional National Guard members and law officers. Authorities also announced a 7 p.m. curfew, an hour earlier than the night before.

“A senseless tragedy like this cannot happen again,” the governor, a Democrat, said in a statement. “I again ask those who choose to exercise their First Amendment rights please do so peacefully and safely, as so many did last night. I also ask the individuals who are not there to exercise those rights to please stay home and let local first responders, law enforcement and members of the Wisconsin National Guard do their jobs.”

In Washington, the Justice Department said it is sending in more than 200 federal agents from the FBI, U.S. Marshals Service and the Bureau of Alcohol, Tobacco, Firearms and Explosives in response to the unrest.
