KATY, Texas (AP) — Authorities in Fort Bend County say they’ve recovered a rifle that’s connected to the shooting last week of a married couple at their upscale Katy home.

Sheriff’s officials said a warrant was obtained Tuesday to search a vehicle that was being driven by 20-year-old Ryan Walton when he was arrested Saturday. They say a .22-caliber rifle was found inside. It will undergo ballistic testing.
