Pfaff says the Navy is investigating. This is the second death under similar circumstances at the boot camp in the past two months. According to the Military Times, Seaman Recruit Kierra Evans was pronounced dead at a hospital after she collapsed following physical training Feb. 22.

“For me, I’m just like what’s wrong?” Harold Nobles told WKRG-TV. “These young people are so excited about serving their country and going into the military. Are they doing enough to check them? Does physical testing need to be more in-depth?”
