What happened to Jacob Ybarra?
Jacob Ybarra was shot to death with a Glock 9 mm in his sleep in the early hours of April 18, 2021, along with his cousin Sabion Kubitza. The two men met with their deaths at the hands of their friend and star football player, Zamar Kirven, who was reportedly high on LSD.
On the evening of April 17, 2021, Kirven, Kubitza, and Ybarra were reportedly on their way to Limestone County to get LSD. A fourth friend and Kirven's best friend, Shatydrick Bailey, was with them but parted ways to attend a party. As reported by KWTX, Bailey was walking about eight blocks to the CEFCO store around 1 am to grab something to eat when he thought he heard three gunshots.
He encountered a disoriented Kirven on his way back and was cornered by him with his pistol in his hand in the house. As Bailey escaped his death narrowly, Ybarra was found dead on the floor in Kubitza's bedroom with gunshot wounds to his left shoulder, left arm, and head. Sabino Kubitza was dead on the bed, having suffered gunshot wounds to his right jaw and forehead.
Zamar Kirven is presently incarcerated at the McLennan County Jail.
