A Humble, Texas man was sentenced to 75 years in prison for killing a 22-year-old acquaintance, then putting the murder weapons up for sale just minutes later.

Twenty-year-old Siten Anney was found guilty by a jury after a four-day trial for shooting and killing Trevor Alan Harrison on Nov. 23, 2020.

The two men knew each other, according to Harris County District Attorney Kim Ogg’s office, and Anney believed Harrison was involved in the killing of another friend a year earlier.

Anney was so convinced that he lured Harrison to an apartment development on Atascocita Road in Humble and fatally shot him in the parking lot with a 9mm semi-automatic handgun.

Anney then fled the scene, and 21 minutes later, attempted to sell the murder weapons online.

Ogg’s office said Anney took a screenshot of an article after the news broke of the fatal shooting, then sent it to his friends, bragging that he stayed up all night to see the story.

Part of the investigation from the Harris County Sheriff’s Office included reviewing messages that Harrison received before dying, which identified Anney as the killer.

"This defendant spent hours doing everything he could to lure this young man to his death, including sending messages and making calls to set up the victim," Ogg said. "We are grateful the jury saw exactly how cold and calculated this murder was and handed down the appropriate sentence."
