“Dr Doug Kelley, a forensic pathologist with the Milwaukee county medical examiner’s office, said Rosenbaum was shot by someone within 4ft. Rosenbaum’s hand, he said, was “in close proximity or in contact with the end of that rifle”.
Kelley said Rosenbaum was shot four times: in the groin, hand and thigh as he faced Rittenhouse and then in the back.”
