Kyle Rittenhouse Trial: Victim Bipolar, Fiancée Testifies, Witness Calls Him Belligerent

A witness who testified in the trial of Kyle Rittenhouse on Friday said that Joseph Rosenbaum, one of the men fatally shot, was acting "belligerently" but did not appear to be a threat, the Associated Press reported.

Rosenbaum's fiancée, Kariann Swart, revealed in her own testimony that he was on medication for bipolar disorder and depression, striking a potential blow against the prosecution's argument that Rittenhouse was the aggressor in the situation.

Rittenhouse, 18, is facing charges of shooting three people, two of whom died, in the summer of 2020 in Kenosha, Wisconsin, where protests broke out over a white police officer's shooting of Jacob Blake, a Black man.

Swart said Rosenbaum was unable to fill his prescriptions before his death because the local pharmacy was closed and boarded up during the unrest.

The defense was able to probe into Rosenbaum's mental illness because of the prosecution's mention of his medication. It is unlikely that the judge would have allowed the defense to bring up the topic if prosecutors had steered clear of it, AP reported.

Jason Lackowski, a prosecution witness, said that Rosenbaum was acting "belligerently" when he encountered him in Kenosha the day he was shot but perceived him as a "babbling idiot" rather than a true threat. His description contrasted other testimony that Rittenhouse, who was 17 at the time, might have viewed Rosenbaum as a threat.

Lackowski, a former Marine who said he took an AR-15 semi-automatic rifle to Kenosha last year to help protect property during violent protests against racial injustice, said that Rosenbaum "asked very bluntly to shoot him" and took a few "false steppings ... to entice someone to do something."

Lackowski got up from the witness stand and demonstrated what he called "false stepping." He took a small step and slight lurch forward, then stopped.

But Lackowski said he turned his back and ignored him. He admitted he didn't see everything that went on between Rittenhouse and Rosenbaum, including their final clash.

On the day he was shot, Rosenbaum had been released from a Milwaukee hospital. The jury was told that much, but not why he had been admitted — after a suicide attempt.

Rittenhouse is white, as were those he shot. Prosecutors have portrayed Rittenhouse as the instigator of the bloodshed, while his lawyer has argued that he acted in self-defense, suggesting among other things that Rittenhouse feared his weapon would be taken away and used against him.

On Thursday, witnesses testified that a belligerent Rosenbaum angrily threatened to kill Rittenhouse that night and that Rosenbaum was later gunned down after he chased Rittenhouse and lunged for the young man's rifle.

A state crime lab DNA analyst testified Friday that she tested the barrel guard from Rittenhouse's rifle and did not find DNA from Rosenbaum or the other man killed that night, Anthony Huber. But Amber Rasmussen said she received no swabs from the actual barrel of the gun and would have no way of knowing if Rosenbaum touched it.

Under cross-examination by Rittenhouse attorney Corey Chirafasi, Rasmussen was shown still images of Huber and Rittenhouse and agreed they appeared to show Huber touching the rifle. She also acknowledged that the absence of Huber's DNA on the gun doesn't mean he didn't touch it.

In testifying about patrolling the streets of Kenosha against protest violence, Lackowski and another veteran, former Army infantryman Ryan Balch, both used military terminology that reflected their backgrounds.

Lackowski referred to "areas of occupation," talked about taking up his "post" in a parking lot, and said he was trained in "shout, shove, show, shoot."

"You shout, you shove, you show your firearm and you shoot," Lackowski explained.

Balch used the term "plate carrier," which he explained means body armor. He gave a detailed explanation of the differences between full metal jacket bullets and hollow points, and talked about ensuring the armed citizens in Kenosha that night worked in pairs to protect each other.

According to testimony, Rosenbaum, 36, was unarmed and did not hurt anyone that night. During the clash with Rittenhouse, Rosenbaum threw a clear plastic hospital bag that he had been given to hold his toiletries.

Rosenbaum's fiancee testified that hours before he was killed, she told him not to go to downtown Kenosha because of the unrest.

"When he left, he said that he would see me in the morning and he was all excited and 'I love you.' It was a pleasant visit," Swart said.

After getting a call from the medical examiner that Rosenbaum had died, Swart said, she fell to her knees and cried and then found a video online showing him dying: "I broke down and I can't get that image out of my head."

In the morning, Swart said, she went to the spot at a car dealership where Rosenbaum lay on the ground after being shot. "And I put my hand in it and my hand was wet with his blood," she said. "And that's again when I collapsed on the ground."

Rosenbaum's killing has emerged as one of the most crucial moments that night because it set in motion the bloodshed that followed moments later.

Rittenhouse shot and killed Huber, a 26-year-old protester seen on bystander video hitting Rittenhouse with a skateboard. Rittenhouse then wounded Gaige Grosskreutz, 27, who had a gun in his hand as he stepped toward Rittenhouse.

Rittenhouse could get life in prison if convicted in the case that has stirred furious debate over self-defense, vigilantism, the right to bear arms and the racial unrest that erupted around the U.S. after the killing of George Floyd in Minneapolis and other cases like it.
