KAMPALA, Uganda — A forensic chemist testified Monday that no gunshot residue was found on the hand of a woman accused of killing her husband, a key piece of evidence her defense is expected to emphasize in the closely watched murder trial.
Dr. Jaffar Kisitu, a forensic chemist with the Uganda Police Forensic Examination Department, told the court he analyzed samples taken from Molly Katanga in connection with the death of her husband, Henry Katanga. Molly Katanga is charged in his death.
Under cross-examination by defense lawyer Elison Karuhanga, Kisitu detailed his analysis of gunshot residue (GSR) on swabs from Molly Katanga’s hands and clothing.
He explained that diphenylamine (DPA) alone isn’t enough to confirm GSR; the analysis must also detect DPA’s breakdown products, such as 2-nitro-DPA (2nDPA).
Kisitu said one swab from Molly Katanga’s right hand tested negative. Another contained DPA and nitroglycerine but lacked the necessary derivative, 2nDPA.
Asked by Karuhanga if the findings could be classified as gunshot residue, Kisitu said they could not.
Karuhanga then asked Molly Katanga to raise her right hand, which she did, revealing the missing top portion of her pinky finger – a visual reminder of the day her husband died.
“On that hand… no GSR… right?” Karuhanga asked. Kisitu confirmed.
The testimony contrasts with earlier forensic evidence that Molly Katanga’s DNA was found on the pistol recovered at the scene, specifically around the trigger. The defense has questioned the handling of that evidence, noting no fingerprint matches and suggesting possible secondary DNA transfer.
The defense has also raised concerns about potential procedural errors, including whether the correct firearm was examined.
The trial continues this week, and the lack of gunshot residue on Molly Katanga’s dominant hand is expected to be a central part of her defense.
