On Wednesday night, August 20, 2025, former boxer Quenton Brown and a youth football coach, later identified as Cross Tupuola, allegedly had a disagreement that led to Cross fleeing with multiple stab wounds. According to reports, the disagreement began when Brown’s SUV parked next to Tupuola’s car, where the latter was sitting with his girlfriend.

According to reports, Quenton Brown came out of his car, and his passenger door hit the driver’s side of Cross’s car. The young football coach came out of his vehicle to check the damage. However, Brown immediately became confrontational, saying “it was just a bump” and calling Cross a “b*tch *ss.”

The two men continued the back and forth, and according to Cross’ girlfriend, who was also present, her boyfriend slapped the side mirror of Brown’s SUV. After a while, the men decided to resolve the issue, and when Cross turned his back to go back into his vehicle, he was immediately attacked from behind by Brown.

“[He] briskly walked after him while producing an unknown object from his right side [and]swung his arm in a straight stabbing motion and struck [the boyfriend] in his back,” Cross’ girlfriend said.

And while Cross tried to fight back, he was overpowered by Brown, a boxer with a 33-18-1 record and 25 knockouts in the ring. Cross was reportedly stabbed multiple times in the stomach. According to an eyewitness, he was stabbed “25 times.” Tupuola fled to his car and was driven to a pharmacy near Fort Apache Road and Sahara Avenue to wait for an ambulance.

According to doctors’ reports, Tupuola suffered from several stab wounds to his back, left hand, and upper right clavicle area. The coach also had a broken right rib that might require surgery. News sources report his condition as critical.

Quenton Brown was arrested near Decatur Boulevard and was taken to UMC, where he refused to be interviewed. When found, Quentin was covered with blood stains; however, the weapon used in the incident wasn't recovered.

Quenton Brown’s bail has been set at three hundred thousand dollars.
