During a road sweep northeast of the An Hoa Combat Base in the Duy Xuyen District of Quang Nam Province, PFC Kellar, who was a member of the security patrol, tripped and activated a mine causing the BT (Booby Trap) hidden 105mm artillery shell to detonate near the Phu Nhuan village complex. The explosion killed the young Marine from multiple fragmentation wounds.
