Fatal police shooting of man officials say was armed with knife prompts investigation and protests in Wisconsin

(CNN) — A man was shot and killed in a struggle with police officers in Madison, Wisconsin, after officials say he pulled out a knife and injured an officer – a confrontation that is being investigated by the state and has sparked outcry from protesters.

Police had received a report of a person allegedly checking parked vehicles Wednesday afternoon and arrived to find a man, described as being in his 30s, Madison Police Chief John Patterson said during a news conference Wednesday.

Officers tried to make contact with him, but he fled on his bicycle through nearby backyards, according to police.

Officers found the man again less than two miles from the state Capitol and “a physical struggle ensued,” Patterson said. The man pulled out a fixed-blade knife and injured one officer, described as a “veteran officer,” as they attempted to arrest him, the chief added.

Bystander video filmed from a nearby car shows officers on the ground at an intersection, struggling with a man who is then pulled up to his feet. One officer appears to have deployed a Taser as the man falls to the ground again and is kicked by another officer as a third holds him down with his knee.

A fourth officer then fires his gun at the man at close range. Three gunshots are heard as the man stops moving, the video shows. It’s not clear what happened before the video began.

Officers had deployed a Taser, but it was “not effective,” Patterson said. The officer who had been injured by the knife fired his weapon, striking the man and causing life-threatening injuries. The man – who has not been named – was taken to a hospital, where he later died.

None of the officers involved were wearing body cameras, according to the police chief, adding the department does not have “any broad deployment of body cameras in Madison, unfortunately.”

As footage of the incident circulates on social media, Patterson said the footage is just one perspective of the encounter. He added that the Wisconsin Department of Justice’s Division of Criminal Investigation — which is independently leading the investigation — will review all footage posted online or submitted directly to the agency to assess the situation.

Authorities are also investigating whether the man fell from his bicycle or was physically removed by officers when they encountered him near the intersection of Williamson and South Baldwin streets on the city’s Near East Side, the police chief said.

A second officer was injured in the incident, though Patterson said it’s unclear how the injury occurred. He added authorities don’t believe the injury was caused by the man’s knife.

All four officers involved have been placed on administrative leave pending the investigation, Patterson said.

CNN reached out to the Madison Police Department for additional information and was referred back to an incident report.

Patterson started Wednesday’s press conference by acknowledging the shooting was a traumatic incident that “has occurred in a neighborhood that has experienced a lot of trauma in the past.”

On the same street in 2015, a White police officer shot and killed an unarmed, biracial 19-year-old, Tony Robinson, leading to major protests. The race of the victim and the officer from Wednesday’s shooting have not been disclosed.

Peaceful protesters gathered in Madison on Wednesday, chanting, “No justice, no peace.”

Watch an orca ram a sunfish so hard that the fish explodes

(CNN) — How hard do you have to ram a fish to make it explode? Ask an orca.Barreling into large, heavy fish with enough force to blast them into instant chum is a previously unknown collaborative feeding strategy among orcas, scientifically called Orcinus orca, also known as killer whales.But in 2024 and 2025, divers captured underwater video of two such events in the Mexican Pacific Ocean and in the Gulf of California. The footage suggests that the brutal body slamming may be in service of a meal — or perhaps a form of play for the orcas, researchers reported Thursday in the journal Frontiers in Ethology.“I filmed the first event several years ago and couldn’t believe what I was witnessing,” said lead study author Kathryn Ayres, a research scientist for the marine conservation nonprofit Beneath the Waves and the first to capture orcas’ high-speed ramming on video.Ayres studies sharks but observing orcas that preyed on sharks in the Gulf of California sparked her interest in killer whale behavior. She filmed the encounter on July 29, 2024, while diving as an ocean safari tour guide with the group Latitude Encounters, near the coast of San José del Cabo in the Mexican state of Baja California Sur.“The cooperative ramming behaviour itself wasn’t entirely new to me, as I had previously observed similar coordinated ramming during a hunt involving a whale shark,” she told CNN in an email.Orcas have also made headlines in recent years for teaming up to ram and sink yachts in waters near Spain and Portugal.“What was unique in this case was the outcome,” Ayres said. “Seeing the sunfish fragment into countless pieces was unlike anything I had encountered before.” Her astonishment was audible as she recorded the ramming episode. “Oh, god!” she repeatedly exclaimed.‘Newly documented behavior’A second video of orcas holding and then ramming a sunfish was filmed by another tour operator in the Gulf of California in September. Both incidents demonstrated teamwork; one orca held a sharptail sunfish, scientifically named Masturus lanceolatus, by its tail, while another orca swam toward the fish at high speed. Moments before impact, the restraining orca let go, and its partner slammed into the sunfish like a freight train hitting a watermelon. Young orcas then gobbled up fish fragments that drifted through the water as their elders tore into what was left of the sunfish’s corpse.Sharptail sunfish, or molas, are among the heaviest fish in the world, weighing more than 4,000 pounds (1,800 kilograms) and measuring up to 10 feet (3 meters) long.Orcas often coordinate their attacks in pairs or groups when they target large prey. However, this torpedolike body slam and subsequent fish explosion had never been observed before and was “an incredible behavior to see,” said Monika Wieland Shields, director of the Orca Behavior Institute. Shields was not involved in the new research.“I have never heard of anything similar to this occurring, so it is indeed a newly documented behavior as far as I know,” Shields told CNN in an email.Though all orcas belong to a single species, their diets vary widely depending on where they live. Orcas’ prey may include fish, seals, belugas, narwhals, baleen whales or porpoises, and can require specialized feeding tactics — including, it seems, high-impact fragmentation.“I think that as we continue to observe orcas more closely around the world,” Shields added, “we will continue to discover novel hunting and feeding behaviors, especially among lesser-studied populations.”‘Just for fun’Ramming the sunfish and causing them to explode could help orca calves and juveniles get more of the remains, according to the study. What’s more, working together strengthens social bonds in orcas, as do shared meals. An exploded sunfish spread out in the water in thousands of pieces is certainly easier to share, offering another possible explanation for this practice.But orcas are also known to play with newly dead food. Some orcas in Puget Sound off Washington state have worn dead salmon as hats. Others drape seal intestines over their fins or take turns tossing sea lion pelts into the air, Shields said.“We’ve also seen interactions with many other objects including bull kelp, driftwood, and crab pots,” she said, “In many of these cases there doesn’t seem to be a functional reason for these behaviors other than play.”In other words, it’s possible that orcas body-slam sunfish purely for entertainment. Ayres noted a large wound on the fish’s body before the impact, which hinted that the orcas feasted on the creature before slamming it to pieces.“They had already consumed the sunfish’s internal organs, which are the most nutrient-rich parts of the prey,” Ayres told CNN in an email. “This suggests that causing the sunfish to explode may not have served an immediate feeding purpose and could have just been for fun.”The sunfish’s flattened body structure is unusual in large fish and could make them more likely to fly apart after a high-speed orca impact compared with other types of fish, Ayres added.“Their bodies are laterally compressed,” she explained. “Once the nutrient-rich internal organs have been removed, the remaining tissues may be more accessible to rupture under high-impact ramming.”But for now, she cautioned, this is only a hypothesis.“We haven’t seen this type of prey fragmentation described in other sunfish species,” she said, “so it’s difficult to know whether it reflects something unique about the anatomy of Masturus lanceolatus, the specific behaviour of these orcas, or a combination of both.”The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
