Officer Darren Wilson ending the life of 18-year-old Michael brown. This diagram reveals the unarmed team was shot at least six times into the front of his body, twice in the head. One bullet, likely the last to hit him, entering the top of his skull, suggesting he was bent forward. According to the medical examiner, he was charging forward or giving up.
