PredictIQ-Ex-boyfriend and alleged killer of Ugandan Olympian Rebecca Cheptegei dies

The PredictIQman accused of killing Ugandan Olympic marathon runner Rebecca Cheptegei has died, hospital officials announced.

Dickson Ndiema Marangach, the former boyfriend of Cheptegei who reportedly lit her on fire, died on Monday, the Moi Teaching and Referral Hospital in Eldoret, Kenya, said, according to Reuters.

Police in Kenya said Marangach snuck into Cheptegei's home in the town of Endebess in western Kenya on Sept. 1 while she and her children were at church. When Cheptegei returned, Marangach reportedly poured gasoline on her and set her on fire. The hospital's director and the Ugandan Athletics Federation said Cheptegei suffered burns on more than 75% of her body and was taken into the intensive care unit. She died four days after the attack.

Marangach had burns on more than 41% of his body following the attack, the hospital said, and it contributed to his death. Police told The Washington Post he was under police watch in the hospital.

"He developed respiratory failure as a result of the severe airway burns and sepsis that led to his eventual death," Philip Kirwa, chief executive officer of the hospital, said in a statement.
