Enrique Delgado-Garcia, 25, died at a hospital on Friday, a day after the exercise at the Massachusetts State Police Academy in New Braintree, department spokesperson Tim McGuirk said in a statement Friday night. New Braintree is about 80 miles northeast of Boston.

McGuirk said the academy’s on-site medical team responded immediately after Delgado-Garcia became unresponsive. They determined that he required urgent medical care and took him to the hospital.

Such police training can cover a range of physical encounters to defend against tackles, punches and other attacks. McGuirk’s statement did not specify the type of exercise Delgado-Garcia took part in. He did not immediately respond Saturday to further questions about that or whether Delgado-Garcia was injured.

“The matter is under review and the review has been active and ongoing since we were notified of the incident on Thursday,” Lindsay Corcoran, a spokesperson for the Worcester County District Attorney’s office, said in a statement Saturday. Delgado-Garcia once worked as a victim witness advocate in that office.

Delgado-Garcia’s mother told reporters with NBC10 Boston and Telemundo Nueva Inglaterra that he was hit and injured.

“I don’t understand why it was so rough if it was just training,” Sandra Garcia said in Spanish. “I want them to explain it to me, that the state explains to me what happened with my son. … Why did he hit him so hard that it killed him, that it destroyed his brain and broke all of my son’s teeth and he had a neck fracture too, my son.”

Col. John Mawn Jr. of the state police said in a statement that his department “is committed to providing support and resources to Trainee Delgado-Garcia’s family, friends, and fellow academy recruits in the coming days and weeks as they cope with this unimaginable loss.”

Massachusetts Gov. Maura Healey issued a statement saying she was heartbroken about the loss of Delgado-Garcia.

“He was a beloved member of his academy class, known for his compassion and devotion to service. This is a devastating time for all who knew and loved him, and we are holding Enrique’s family and his State Police community in our hearts,” she said.
