"Recruit Chase will be missed by all who knew him," according to an agency statement posted on Facebook. "Our thoughts and prayers go out to the family as well as Class 129."
Chase, who entered the academy on May 25, was participating in a two-week training block called "custody, control, and defensive tactics" when the injury occurred.
"It was basically a freak accident," Capt. Dexter Nelson told POLICE Magazine.
The instructor was demonstrating a take-down maneuver on Chase, when the recruit hit his head and didn't get up. At this point, it doesn't appear the instructor is at fault, Nelson said.
"They're not trying to knock people's heads off," Nelson said. "They're doing it at a speed where they can handle it, but where they can show proficiency of the technique."
