After four deployments to Afghanistan and three to Latin America, Duke Webb returned home a different and damaged man. He had sustained traumatic brain injuries during his service and developed severe post-traumatic stress disorder.

By late 2020, his mental health had deteriorated significantly. The Army prescribed Webb Memantine, a neurological drug typically used to treat Alzheimer's disease.

Weeks later, on December 26, 2020, Webb entered Don Carter Lanes and opened fire, believing those around him were “the enemy.” Three people died and three others were seriously injured.

Webb does not deny the shootings. His defense argues that the Traumatic Brain Injury (TBI), Post Traumatic Stress Disorder (PTSD), along with Army-prescribed medication triggered a catastrophic psychotic break.

Prosecutors contend he acted knowingly and should spend the rest of his life in prison without the possibility of parole.
