Captain Ernest Medina is acquitted of all charges relating to the My Lai massacre of March 1968. His unit, Charlie Company, 1st Battalion, 20th Infantry, 11th Infantry Brigade (Light) of the 23rd (Americal) Division, was charged with the murder of over 200 Vietnamese civilians, including women and children, at My Lai 4, a cluster of hamlets that made up Son My village in Son Tinh District in Quang Ngai Province in the coastal lowlands of I Corps Tactical Zone.
Medina had been charged with murder, manslaughter, and assault. All charges were dropped when the military judge at the Medina's court martial made an error in instructing the jury. After the charges were dropped, Medina subsequently resigned from the service. There were 13 others charged with various crimes in conjunction with the My Lai massacre, but only one, Lt. William Calley, was found guilty. Calley was sentenced to life imprisonment for the murder of 22 civilians, but his sentence was reduced first to 20 years, then 10 years, and he was ultimately paroled by President Nixon in November 1974, after having served about one-third of his sentence.
