Three Army Reserve officials have been disciplined following the conclusion of an investigation into the details surrounding the Oct. 25, 2023, mass shooting in Maine carried out by Sgt. 1st Class Robert Card.

Card, who joined the Army Reserve in 2002 as a petroleum supply specialist, had displayed a series of distressing signs that concerned his family, friends, and unit, and he was hospitalized briefly, but there were several failures that ultimately allowed for the conditions for him to carry out the shooting that left 18 people dead and another 13 wounded. He killed himself while on the run after the shooting, and his brain, which doctors have studied and continue to, had shown signs of traumatic injury.
