In June 1966, just a few weeks after the market day massacre in My Luoc, an elderly man named Tran Lanh was walking to the refugee camp at Ai My when marines shot and killed him along with several other civilians. The next day, Lanh’s son Tran Cau, a high school student, received permission from the local district chief to travel along with three men to retrieve his father’s body. On the instructions of the official, who had cleared the plan with a local U.S. Marine commander, the men wore white clothes, carried a white flag with a red cross, and brought a letter of introduction written in English. Nevertheless, marines seized and blindfolded the four Vietnamese, tore up their letter and the flag, and marched them a long distance away. Eventually, the Americans removed their blindfolds and told them to go. When the Vietnamese had walked about 130 feet, however, the marines opened fire on them, killing Cau and one of his companions and wounding another.
