Rebecca Cheptegei was set alight and later died after Dickson Ndiema ambushed her near her home.
The former boyfriend of Ugandan Olympic athlete Rebecca Cheptegei, who killed her by setting her on fire, has himself died from burns sustained in the attack, a Kenyan hospital official has said.
Dickson Ndiema ambushed the marathon runner as she returned home from church more than a week ago. He then doused her with petrol and set her ablaze.
Local administrators said the two had been in conflict over a small piece of land in north-west Kenya, where Cheptegei lived and trained.
