An expert has confirmed that Kyle Rittenhouse shot the first victim he saw during the chaos in Kenosha (Wisconsin), just seconds after firing a gunshot in the air.

Dr. John Black, who is an expert on use-of-force cases and video evidence, testified about footage that he analyzed for Rittenhouse’s murder trial on charges that he fatally shot two men and injured a third as riots broke out in the city last summer.

Asked about the time between the shot fired by another protester and Rittenhouse opening fire, Black said that the gap was only about “two and three quarters” seconds.

Rittenhouse’s lawyers have argued that the teen feared for his life when he shot his first victim that night, Joseph Rosenbaum.

Black’s testimony comes after an explosive day in court Wednesday in which Rittenhouse broke down on the stand as he described the events leading up to the shootings on Aug. 25. 2020

Rittenhouse’s nearly daylong testimony was interrupted by fiery exchanges between the prosecutors and the judge, who at one point suggested they were acting in bad faith with their line of questioning.

Rittenhouse’s lawyers also cited what they said were out-of-bounds questions directed at their client in requesting a mistrial on Wednesday.

Kenosha County Circuit Judge Bruce Schroeder didn’t immediately rule on the matter.

Schroeder indicated that the trial could wrap up this week, saying that it would be “ideal” if closing arguments were held Friday.

Rittenhouse is facing six charges including the intentional homicide of Rosenbaum, Anthony Huber, and Gaige Grosskreutz being shot.

Rittenhouse has been accused of being the aggressor in the violence. His lawyers, however, claim that Rittenhouse only acted in self defence.

If convicted of intentional homicide, which is the state’s equivalent of murder, he faces a mandatory sentence of life in prison.
