In his defence, Mr Nyakeo denied sexually assaulting the elderly woman.
He claimed that someone took his DNA from a used condom and planted it on the victim’s body.
His colleague however, who testified against him, said he had told his friends to lie to the court during the trial.
A Kenyan man has been sentenced to life imprisonment by a US court for sexually assaulting a 74-year-old patient at a medical facility where he was working.
Anthony Mamboleo Nyakeo, 53, was convicted Wednesday of two counts of aggravated sexual assault of an elderly or disabled person.
A Texas court handed him a life sentence on each account.
Nyakeo’s victim was living at the Woodridge Health and Rehabilitation Center in Grapevine, Texas when the crime occured in January 2018. She died late last year aged 75.
Evidence filed in court showed that the sexual assault was discovered after other nurses working at the facility found blood in the underwear of the victim.
