Investigation launched after death of Navy Seal candidate prompts overhaul of how 'Hell Week' training course is monitored

Inadequate medical screening and uninformed medical staff contributed to the death of a Navy SEAL candidate hours after he had completed a brutal part of the training course known as "Hell Week," a Navy investigation found.

The investigation prompted an overhaul of how the Navy monitors one of the military's most brutal and demanding processes.

It found that the medical support for the Basic Underwater Demolition/Sea Air and Land course was "poorly organized, poorly integrated, and poorly led," wrote Rear Adm. Peter Garvin, the commander of Naval Education and Training Command. The lack of proper medical care "put candidates at significant risk."

The course is designed to push SEAL candidates to the limit and beyond, creating an environment where only the most qualified and capable will finish, but Garvin said there must still be "effective risk management" to prevent injuries and illness during the high-risk training.

In February 2022, Navy SEAL candidate Kyle Mullen had just completed Hell Week and underwent a final medical check before he went to rest at his barracks. The investigation found Mullen had suffered respiratory issues during the arduous training, but information about the symptoms was not passed on to the Navy's medical clinic, leading them to conclude he was not at risk.

Eight hours later, Mullen was pronounced dead.

In the hours before his death, Mullen was coughing up an "orange-red fluid" and having trouble breathing, according to the investigation. Even as he repeatedly refused advanced medical care, he appeared to be choking on his words and gasping for air as if he was drowning. But the personnel assigned to check on Mullen and other SEAL candidates, known as watch standers, had no medical or emergency care training.
