Angela Michelle Thompson, 45, was shot and killed in the 400 block of South Hadden Avenue in El Reno, Oklahoma, on the evening of March 10, 2021. Police arrived just before 9:30 p.m. and found Ms. Thompson deceased at the scene; two other people were injured in the same shooting.

Investigators identified 21-year-old Jason Lamar Richey as a suspect and took him into custody shortly after the shooting. The case narrative reports an altercation two days earlier between Richey and Ms. Thompson’s son, and alleges Richey warned the son that if he couldn’t get him he would go after the son’s family. Prosecutors put forward evidence, including DNA linking the murder weapon to Richey, and he was charged with first-degree murder and with shooting the two other victims.

What details about the hours before the shooting or the relationship between the people involved might help explain why this happened? If anyone knew Angela or has information about that night, please come forward.
