Police: Wisconsin Shooter Likely Killed Self

CRANDON, Wis. – An off-duty deputy who killed six people likely shot and killed himself, Attorney General J.B. Van Hollen said Tuesday.

Tyler Peterson, 20, was shot four times, Van Hollen said. He was shot once in the left biceps from a distance and then three times in the head from a gun at close range. Two shots went in under Peterson's chin, while the third fatal shot entered through the right side of head, he said.
