According to the Upshur County Criminal District Attorney’s Office, Alvin “Pookie” Charles McKnight, Jr., 41 of Gilmer, was indicted on capital murder after being arrested in November 2023 when investigators found two sisters dead.

The Upshur County Sheriff’s Office said that the shooting happened at a house in the 2800 block of U.S Highway 271 South near Bluebird Road. When deputies arrived at the scene, they reportedly found Mandy Ray, 35 of Gilmer, and Dermetrica Dashaunda Waters, 37 of Gilmer, dead from apparent gunshot wounds.

In a press conference, the sheriff’s office said the two victims were sisters and that Waters had a child with McKnight and had once lived with him.

His sister, Laquesha Monique McKnight, 38 of Longview, was arrested for allegedly hindering the apprehension of Alvin. Officials said Laquesha helped Alvin escape from the Upshur County area on the night of the murders and when the sheriff’s office confronted her with evidence, she was reportedly not cooperative.

McKnight was brought into custody at the Upshur County Jail after being apprehended in San Bernadino, Calif. on Nov. 15, 2023.
