Kenyan world record holder Agnes Tirop has been found dead at her home in the western town of Iten, with police treating her husband as a suspect.
The two-time World Athletics Championships bronze medallist, who finished fourth in the Olympic 5,000m final two months ago, was 25.
Police say her husband has gone missing following her death.
On Wednesday, crime scene investigators were at the house of Tirop, who police say was reported missing by her father on Tuesday night.
“When [police] got in the house, they found Tirop on the bed and there was a pool of blood on the floor,” Tom Makori, head of police for the area, said.
“They saw she had been stabbed in the neck, which led us to believe it was a knife wound, and we believe that is what caused her death.
“Her husband is still at large, and preliminary investigations tell us her husband is a suspect because he cannot be found. Police are trying to find her husband so he can explain what happened to Tirop.”
Makori added that police believe that CCTV in the house may be able to help with their investigation.
Tirop was also found dead with a stab wound to her stomach, sources have told the BBC.
