The lone survivor shot by Kyle Rittenhouse in Kenosha, Wisconsin, last year said Thursday that he believes the teen’s emotional display at his murder trial was mostly about him being “upset that he was caught” for the shootings.Gaige Grosskreutz, 27, a paramedic shot in the arm, said it was “emotional” to watch Rittenhouse, 18, testify about injuring him and killing two other men last summer as riots broke out in the city over racial injustice.
