RIP

2:08 PM PT -- Moi Teaching and Referral Hospital tells TMZ Sports that Dickson Ndiema's cause of death was due to "inhalation burns and sepsis with resultant pulmonary edema."

Pulmonary edema happens when too much fluid is in the lungs which makes it difficult for someone to breathe.

Dickson Ndiema succumbed to the ailments at a local hospital, authorities said. At the time, it was reported he suffered severe burns in the domestic violence incident that claimed Cheptegei's life.

"At the ICU he developed respiratory failure as a result of the severe airway burns and sepsis that led to his eventual death on Monday at 6:30 PM despite life-saving measures," Kenya's Moi Teaching and Referral Hospital CEO Dr. Philip Kirwa said.
