According to the country’s athletics body, Tirop was found dead at her home in Iten, after being “allegedly stabbed”.
According to local reports, Tirop was found dead with stab wounds to her abdomen.
Athletics Kenya said it was “still in the process of unearthing more details about her death”.
Tirop’s agent, Gianni Demadonna, also confirmed her death by email to CNN.
Athletics Kenya was not immediately available for further comment when CNN reached out to them.
The 25-year-old won bronze medals in the 10,000m at the 2017 and 2019 World Championships and finished 4th in the 5,000m at the Tokyo Games.
Last month, Tirop made history by breaking 28 seconds off the long-standing women’s 10km world record at the Adizero Road To Records event in Germany.
Tirop finished in 30:01, breaking the previous record of 30:29 set in 2002 by Moroccan Asmae Leghzaoui.
After the race she said: “I’m so happy to break the world record. I felt the pace was good. The track was also very good.”
At the 2015 IAAF World Cross Country Championships, Tirop became the second youngest ever gold medalist in the women’s race after Zola Budd.
Athletics Kenya said the country had “lost a jewel that was one of the fastest-rising athletic giants on the international scene, thanks to its eye-catching performance.”
Kenyan President Uhuru Kenyatta also paid tribute, saying in a statement: “It is disturbing, extremely unfortunate and very sad that we have lost a young and promising athlete who at the young age of 25 has brought our country such glory through her achievements on the global athletics podium, including the 2020 Olympics in Tokyo, where she was part of the Kenyan team in Japan.”
