Gregory Donald Galusha, 44, of Oak Run, California, was killed at his home on Stagecoach Road on February 7, 2019. Galusha ran from the house, but Roza pursued him and shot him in the back; Galusha was found face-down in the dirt and was declared dead at the scene.

Roza hid from law enforcement for several days before turning himself in and confessed to the killing, leading to his arrest. Court proceedings were delayed at times because of courtroom unavailability and the absence of key witnesses. A jury found Roza guilty of second-degree murder with a special allegation of using a firearm in December 2024, and he was sentenced in January 2025.
