Mario Castillo, 38, of Odessa, Texas, was shot to death outside his home in the 1000 block of East 90th Street on February 4, 2021. Castillo was struck seven times, including two shots to the heart, after an altercation with 37-year-old co-worker Clinton Saunders.

The confrontation began at the Red Zone bar, where the men had earlier been working on Castillo’s shed and car together. Surveillance video shows Castillo pick up a hat from the passenger side of Saunders’ vehicle and walk toward the driver’s side; several seconds later seven shots are heard and Castillo was found collapsed. Saunders said he acted in self-defense, claiming Castillo had beaten him and was known to carry weapons. The prosecution maintained the fight had ended before the shooting and argued Saunders could have driven away rather than shoot him.

Saunders was arrested March 9, 2021, tried in the 161st District Court of Ector County, convicted of murder on April 6, 2022, and sentenced to 10 years in prison. If anyone knew Castillo or saw the area around East 90th Street that night, can you help fill in what happened?
