Courtney Chandler was 28 when she was found dead inside a home on 11th Street in Ramona, California on the evening of July 6, 2026. San Diego County Sheriff’s deputies responding to an assault with a deadly weapon call discovered Chandler and 32-year-old Nicholas McClure both suffering significant traumatic injuries; emergency personnel pronounced them dead at the scene.

A man later identified as 33-year-old Ryan Wesley Proffitt of Escondido was found sitting on the front steps and was arrested; he was booked on two counts of first-degree murder. Prosecutors have described a relationship dispute as the apparent motive, saying Chandler and Proffitt were in an open relationship and Chandler had recently begun a relationship with McClure, who had moved into the home. During arraignment Proffitt pleaded not guilty and faces special circumstance allegations of multiple murder; authorities say he called 911 after the shooting to report a lover’s quarrel.

Anyone who knew Courtney, Nicholas, or the household situation in Ramona and can share information is asked to come forward.
