black people were said to have buried black victims at the third location after the riot was over. The people who were buried at Washington Cemetery, which is reserved for black people, were probably thought to be those victims who had died of their wounds after the riot had ended, since it was the most distant suspected burial location from downtown. Investigations of the three potential mass grave sites were performed in 1997 and 1998. Even though the total area of all three of these locations could not be surveyed, preliminary data suggested that they contained no mass graves. In 1999, an eyewitness who had seen whites burying black victims at Oaklawn Cemetery was found. A team investigated the potential area with more equipment. In the end, searches for mass graves were made with the aid of technology which included ground-penetrating radar, followed by core sampling. The experts' report, presented to the Commission in December 2000, could not substantiate claims of mass graves in Oaklawn Cemetery, Washington Cemetery, or Newblock Park. A promising spot in Washington Cemetery had turned out to be a layer of clay, and another promising spot in Newblock Park had turned out to be an old basement. The suggestion that the bodies had been burned in the city incinerator was also considered unfeasible and discounted, given the incinerator's capacity and logistical considerations. In preparation for the 100th anniversary of the massacre, state archaeologists, using ground-penetrating radar, probed Oaklawn Cemetery for "long-rumored" mass graves. Mayor G. T. Bynum calls it "a murder investigation." After input from the public, officials from the Oklahoma Archeological Survey used three subsurface scanning techniques to survey Newblock Park, Oaklawn Cemetery, and an area known as The Canes along the Arkansas River. The Oklahoma Archeological Survey subsequently announced that they were discontinuing search efforts at Newblock Park after not finding any evidence of graves. On December 17, 2019, the team of forensic archaeologists announced that they had found anomalies which are consistent with that of human-dug pits beneath the ground at Oaklawn Cemetery and the ground where the Interstate 244 bridge crosses the Arkansas River. They announced that the anomalies are likely candidates for mass graves, but further radar surveys and physical excavations of the sites are needed. Researchers secured permission to perform "limited excavations" from the city and as a result, they will be able to determine what the contents of these
