The Marine Corps said in a statement that Jarrell, 18, enlisted on July 21 and wanted to be in the infantry or serve as a combat engineer. He was scheduled to attend basic training at Marine Corps Recruit Depot Parris Island, S.C. in June 2018.
"Our heartfelt condolences go out to Poolee Tyler Jarrell's family and all of those affected by his loss," the statement said. "The Marines here are greatly saddened by this tragedy. We are truly proud to have known him as one of the brave few willing to step up and serve his country in the United States Marine Corps."
On Saturday, Jarrell's local Marine Corps recruitment station posted to Facebook that he was the first senior from his high school to enlist into the Marine Corps this year.
