DENEEN SMITH Prosecutors are trying to introduce evidence at trial that Kyle Rittenhouse is associated with the Proud Boys and that he had a past violent encounter on Kenoshaâs lakefront. The state filed an âother actsâ motion Thursday asking the court to admit evidence at Rittenhouseâs trial for shooting three men during protests in Kenosha last August. The shooting left two men dead and another seriously injured. Rittenhouse, 18, is charged with two counts of homicide and one of attempted homicide. He and his supporters have maintained that Rittenhouse was defending himself when he shot the men. Kyle Rittenhouse, the Illinois 18-year-old accused of killing two people during the chaotic protests after the police shooting of Jacob Blake in Kenosha, made his first in-person court appearance Friday.
