Olympic athlete Rebecca Cheptegei has died days after her ex-boyfriend doused her with gasoline and set her on fire, a Ugandan official said.

The 33-year-old Ugandan marathon runner, who competed in Paris, suffered severe burns in the attack on Sunday, said the doctor treating her.

Authorities in northwest Kenya, where Cheptegei lived and was educated, said she was targeted after returning home from church.

A local administrator reported that the athlete and her ex-partner had argued over a piece of land. Police said an investigation was ongoing.

The increasing cases of violence against female athletes in Kenya are a cause for concern. Several of these cases have resulted in death.

“We are deeply saddened to announce the death this morning of our athlete Rebecca Cheptegei, who was tragically the victim of domestic violence. As an association, we condemn such acts and demand justice. May her soul rest in peace,” Uganda’s Athletics Federation said in a post on X.

The family has not yet confirmed her death, but Dr. Owen Menach, the head of the Moi Teaching and Referral Hospital in Eldoret where she was admitted, told local media that the athlete died of organ failure.

Cheptegei’s ex-boyfriend was also taken to hospital – but with less severe burns.

Her father, Joseph Cheptegei, told reporters earlier this week that he was praying “for justice for my daughter,” adding that he had never witnessed such an inhumane act in his life.

Her death came two years after the murders of fellow East African athletes Agnes Tirop and Damaris Mutua; in both cases, authorities identified their partners as prime suspects.

Tirop’s husband is currently facing murder charges, which he denies, while the manhunt for Mutua’s boyfriend continues.
