The Massachusetts State Police trooper is due in Boston court on Wednesday over Enrique Delgado-Garcia's 2024 death after a boxing exercise at the academy in New Braintree.
Prosecutors say LaMonte and three other instructors let Delgado-Garcia enter the ring a day after concussion-like symptoms, alleging reckless conduct that led to his death.
The other three troopers pleaded not guilty last month to involuntary manslaughter and serious bodily injury charges; all four were suspended and the recruit boxing programme was halted.
Will prosecuting trainers for recruit deaths make police academies safer or dangerously hesitant?
