On Friday morning, Kenya's Directorate of Criminal Investigations released photographs of a man sitting in custody at a police station in the coastal city of Mombasa.
Wearing a Christmas t-shirt, a mask tucked under his chin, his wrists bound by handcuffs, he stares blankly up into the camera.
This man, identified as Ibrahim Rotich, is the prime suspect in the murder of Agnes Tirop, an Olympic track star who was found dead in her Iten home on Wednesday.
The 25-year-old was in a relationship with Rotich, who was arrested on Friday morning attempting to flee the country.
Mourning a champion.
Agnes Tirop's death has plunged the global athletics community into mourning.
World Athletics CEO Sebastian Coe described the 25-year-old as "one of the world's best female distance runners over the past six years".
"Athletics has lost one of its brightest young stars in the most tragic circumstances," he said. "This is a terrible blow to the entire athletics community, but especially to her family, her friends and Athletics Kenya and I send them all our most heartfelt condolences."
Tirop stunned her competitors when at just 19 years old she claimed victory at World Cross Country Championships in Guiyang — the second-youngest woman in history to secure the title.
From 2017, she specialised in the 10,000m, earning two World Championship bronze medals on the track and a world record at a road race in Herzogenaurach earlier this year.
Tirop also represented Kenya at the Tokyo Olympics, where she placed fourth in the 5,000m.
