Robert Stewart, 49, was fatally stabbed at his southeast Houston home on August 16, 2020. Police reports say the attack was carried out with a foot-long curved sword described as a pirate sword; witnesses said Stewart’s younger brother, identified as 29-year-old Cory Madison Kellett, confronted him outside the house, slashed his neck, and Stewart died about 40 minutes after being taken to hospital.

After the stabbing, Kellett reportedly fled the scene in an Alfa Romeo and was named the primary suspect. An arrest warrant was issued charging him with murder and aggravated assault with a deadly weapon. Reports cite a history of prior altercations between the brothers.

Does anyone have information about the days leading up to the killing or witnessed the confrontation outside the house?
