Derrell Rafael Quinney, 34, was fatally shot on September 11, 2023, in the Sunnyside neighborhood of Houston. Officers responded to reports of a shooting around 1:30 p.m. in the 3700 block of Grassmere Street near Scott Street; Quinney was found unresponsive with a gunshot wound and was pronounced dead at the scene by the Houston Fire Department.

Investigators identified Quinney’s brother, 30-year-old DaMarcus Williams, as the suspect. Williams was detained at the scene, questioned, and later charged with murder in the 263rd State District Court. Court documents note a 2012 conviction for aggravated robbery with a deadly weapon. Authorities have not disclosed a motive.

Quinney, born August 11, 1989, was one of four children and a 2007 graduate of Evan E. Worthing High School. Remembered for his love of cooking and generous nature, he was preceded in death by his mother and grandmother and is survived by family including a stepfather, brothers, a girlfriend, and several nieces and nephews. Did anyone in the Sunnyside community see or hear anything that afternoon that could help?
