After an intensive investigation, there is no evidence to corroborate the allegation that fans used racial slurs during the BYU-Duke volleyball match on Aug. 26, Brigham Young University said Friday morning in a news release.

The investigation included reaching out to more than 50 eyewitnesses, including Duke and BYU volleyball players and athletic department personnel. The university also said its investigation reviewed extensive video and audio of the match.

“We reviewed all available video and audio recordings, including security footage and raw footage from all camera angles taken by BYUtv of the match, with broadcasting audio removed (to ensure that the noise from the stands could be heard more clearly),” the BYU release said.

During the match on Aug. 26, Duke outside hitter Rachel Richardson said she heard racial slurs during the second set while she served two balls in front of the ROC student section of fans.

She told a teammate about the slurs while the teams switched sides of the court following the set, and the two players told Duke coach Jolene Nagel. Nagel spoke with BYU coach Heather Olmstead, and BYU immediately sent a police officer and four ushers into the student section.

Richardson said she heard the slurs more intensely in the fourth set, when the ushers, BYU Police Det. Sgt. Richard Laursen and a Duke assistant athletic director stood near where she served and by the student section.

“I told the (BYU) Athletic staff that I never heard one racial comment being made,” Laursen said in his police report.

After the match, BYU banned a fan who Duke said had used the N-word and had made a player uncomfortable after the match. The fan is not a BYU student.

Laursen stood next to the man throughout the fourth set and said the man did not use any racist language. Laursen said he believed the man may have “(A)sperger syndrome or could have autism.”

BYU dropped the ban on the fan on Friday.

“We have not found any evidence that that individual engaged in such an activity,” the school’s statement said. “BYU sincerely apologizes to that fan for any hardship the ban has caused.”

Duke freshman Christina Barrow, one of four Black players on the team, told The News & Observer in North Carolina last week that she did not hear the slurs, but she and her teammates stood by Richardson.

The match, which 10th-ranked BYU won 3-1, set a school record for attendance in the sold-out Smith Fieldhouse with 5,507 fans. Event officials reported they turned away another 1,000 fans.

BYU’s statement said:

“As part of our commitment to take any claims of racism seriously, BYU has completed its investigation into the allegation that racial heckling and slurs took place at the Duke vs. BYU women’s volleyball match on August 26. We reviewed all available video and audio recordings, including security footage and raw footage from all camera angles taken by BYUtv of the match, with broadcasting audio removed (to ensure that the noise from the stands could be heard more clearly). We also reached out to more than 50 individuals who attended the event: Duke athletic department personnel and student-athletes, BYU athletic department personnel and student-athletes, event security and management and fans who were in the arena that evening, including many of the fans in the on-court student section.

“From our extensive review, we have not found any evidence to corroborate the allegation that fans engaged in racial heckling or uttered racial slurs at the event. As we stated earlier, we would not tolerate any conduct that would make a student-athlete feel unsafe. That is the reason for our immediate response and our thorough investigation.

“As a result of our investigation, we have lifted the ban on the fan who was identified as having uttered racial slurs during the match. We have not found any evidence that that individual engaged in such an activity. BYU sincerely apologizes to that fan for any hardship the ban has caused.

“Our fight is against racism, not against any individual or any institution. Each person impacted has strong feelings and experiences, which we honor, and we encourage others to show similar civility and respect. We remain committed to rooting out racism wherever it is found. We hope we can all join together in that important fight.

“There will be some who assume we are being selective in our review. To the contrary, we have tried to be as thorough as possible in our investigation, and we renew our invitation for anyone with evidence contrary to our findings to come forward and share it.

“Despite being unable to find supporting evidence of racial slurs in the many recordings and interviews, we hope that all those involved will understand our sincere efforts to ensure that all student-athletes competing at BYU feel safe. As stated by Athletics Director Tom Holmoe, BYU and BYU Athletics are committed to zero-tolerance of racism, and we strive to provide a positive experience for everyone who attends our athletic events, including student-athletes, coaches and fans, where they are valued and respected.”

The incident became a national subject of polarized political debate. Some on the right called Richardson’s claims a hoax. Some on the left painted BYU as full of racists.

One columnist said BYU was on trial in the court of public opinion, where it was guilty until proven otherwise — “and maybe not even then, because once the accusation is made, whether it’s proven true or false, the stain remains.”
