[2]: 32 At about 10:00 members of the ROKMC 1st Company, 1st Battalion, 2nd Marine Brigade passed the CAP Delta-2 team (15°55′N 108°14′E / 15.91°N 108.24°E / 15.91; 108.24).

At about 13:30 a Popular Force soldier from CAP Delta-2 brought in two young boys who had been shot and a woman who had been stabbed.

[4]: 3 After 13:30 the CAP Delta-2 members attempted unsuccessfully to contact the U.S. liaison officer at ROK 2nd Marine Brigade headquarters.

[4]: 4 Eyewitness testimony from both the members of CAP Delta-2 and survivors at the hospital accusing ROK forces of responsibility prompted calls for a war-crime investigation from CAP commanders and COMUSMACV, both making direct demands that ROK commander Lieutenant general Chae Myung-shin investigate.

On 16 April 1968 the III MAF reported on the incident to Military Assistance Command, Vietnam (MACV).

Chae stated that there were numerous cases in which the VC used the duck hunter camouflage pattern worn by the ROKMC to commit misdeeds in order to incite unpopular opinion as support for his claim.

[7] On 11 November 2000, Chae conceded that Chief of Staff of the United States Army General William Westmoreland demanded the investigation several times.

[10] Chae still claimed that the two villages were not in the route of the ROKMC and repeatedly continued to blame the VC who allegedly wore the South Korean marine uniforms.
