A 23-year-old soldier who was praised for his actions during the Aug. 3 mass shooting in El Paso, Texas, died this week.

Pvt. Glendon Oakley was found deceased Wednesday in his quarters on Fort Bliss, according to post officials. Oakley’s death is under investigation by special agents from the Army’s Criminal Investigation Command.

“At this point in the investigation, foul play in not suspected,” post officials said in a statement. “No further information will be released at this time to protect the integrity of the investigative process."

Oakley served as an automated supply logistical specialist with the 1st Armored Division Sustainment Brigade. He was a Killeen, Texas native, according to his service history.

Oakley received the Army Commendation Medal in mid-August for his actions during the mass shooting that took the lives of 22 people.

During the attack, Oakley had been at the Cielo Vista Mall shopping at a Foot Locker, adjacent to the Walmart where the shooting unfolded. Both buildings were evacuated by police, and Oakley said he carried several children out of the mall and to police outside.

“You could hear all of the chaos going around, and that’s when I did what I was trained to do,” Oakley said after the incident. “I quickly reacted and I thought to myself if my child were there how I would want someone else to react. I just took action and tried to get as many kids as possible.”

President Donald Trump met with Oakley, as well as others who were impacted by the shooting, which police said was motivated by anti-immigrant and white nationalist beliefs.
