Massachusetts State Troopers are pleading not guilty to manslaughter in the death of an academy trainee. 

On Thursday, Lieutenant Jennifer Penton, troopers Edwin Rodriguez and David Montanez pleaded not guilty.  They are charged in connection with the 2024 death of Enrique Delgado-Garcia. He died after being knocked out during a boxing match at the State Police Academy. 

A special prosecutor said Delgado-Garcia had been in an unauthorized match the day before being knocked out, which resulted in concussion symptoms.
