A government analyst has told the High Court that forensic evidence links secular artist John Matara to the murder of socialite Starlet Wahu.
Ms Emily Okworo, a scientist at the Government Chemist, testified that blood samples recovered from an Airbnb apartment in South B were consistent with those taken from Wahu’s body.

Ms Okworo told the Milimani High Court judge that she conducted DNA analysis on several exhibits, including a kitchen knife and a white towel, both stained with blood.
“After examining the samples, I concluded that the blood on the knife and towel belonged to Starlet Wahu,” she said.
“The stains were confirmed to be human blood and the DNA profile generated was consistent with that of the deceased,” Ms Okworo told the court.

Under cross-examination by defence lawyers Samuel Ayora and James Mochere, Ms Okworo said she also detected traces of blood matching Matara’s profile on some of the specimens.
Mr Ayora also raised questions about blood belonging to an unidentified person that was forwarded to the laboratory.
Ms Okworo responded that investigators indicated the sample had been collected near the main gate, not inside the room where Wahu was found.
The prosecution produced several items recovered from Papino Apartments, including the blood-stained knife, the towel, a pair of women’s shoes and a bra.
A police officer who visited the scene described it as horrifying, telling the court that the deceased appeared to have been brutally attacked.
“This is the weapon we recovered from the apartment,” the officer said while presenting the knife.

The court also heard from Mr Joseph Ndung’u, a security guard at an apartment opposite the scene, who testified that he saw Matara leaving the building wearing blood-stained khaki trousers.
Matara, who remains in custody, denied killing Wahu on the night of January 3, 2024.
