According to the country’s athletics body, Tirop was found dead at her home in Iten, after being “allegedly stabbed”.
Local reports say Tirop was found dead with stab wounds in the abdomen.
Athletics Kenya said he “was still working to find out more details about his disappearance.”
Neither Tirop’s agent – Gianni Demadonna – nor Athletics Kenya were immediately available for further comment when contacted by CNN.
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 scoring 28 seconds of 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 by Moroccan Asmae Leghzaoui in 2002.
After the race, she said: “I am so happy to have broken the world record. I felt the pace was good. The course was also very good.”
At the 2015 IAAF World Cross Country Championships, Tirop became the second youngest gold medalist in women’s running history after Zola Budd.
Athletics Kenya said the country had “lost a gem that was one of the fastest growing athletics giants on the international stage, thanks to its eye-catching performances.”
